Scurvy is a rare nutritional disorder caused by deficiency of ascorbic acid (vitamin C). It is often under-diagnosed in clinical settings, especially in North America where population statistics are unavailable. However, scurvy is more common than previously thought and appears to be re-emerging in children with developmental delays. Here, we review the pertinent literature and present a case of a previously healthy, 5-year-old, non-verbal boy who presented with multiple, acute, and subacute spontaneous epidural hemorrhages managed by neurosurgical intervention. He remained in hospital for 17 days and was seen in follow-up 3 weeks post-operatively having returned to his neurological baseline. Our case suggests the importance of considering scurvy in patients who have developmental delays and poor nutritional status.

The treatment of acute epidural haematoma is surgery as soon as possible, elimination of the source of bleeding and evacuation of the haematoma. In case of small epidural haematoma, strict neurological and radiological follow-up is necessary. In a significant percentage of cases, open surgery must also be performed within a few days. In case of small epidural haematomas, embolization of the middle meningeal artery is considered as an alternative solution. We review the literature on middle meningeal artery embolization and present our first treatment. Our case report is the first European report about an acute epidural haematoma which was treated by embolization of middle meningeal artery. Our case study is the first report in which a patient was treated with both open surgery and endovascular treatment for acute epidural haematoma within a year.

Az akut epiduralis haematoma kezelése a minél korábbi műtét, a vérzésforrás megszüntetése és a haematoma evakuálása. Kis epiduralis vérzés esetén szigorú neurológiai és radiológiai követés szükséges. Az esetek jelentős százalékában ilyenkor is nyílt műtétet kell végezni néhány napon belül. Kis epiduralis vérzések esetén alternatív megoldásként szóba jön az arteria meningea media embolisatiója. Az arteria meningea media embolisatio irodalmát tekintjük át, és bemutatjuk az első ilyen jellegű kezelésünket. Esetismertetésünk az első európai tanulmány, mely során az akut epiduralis haematoma kezelése arteria meningea media embolisatiója által valósult meg. Esetünk az első olyan közlemény, ami arról számol be, hogy egy beteget egy éven belül akut epiduralis vérzés miatt mind nyílt műtéttel, mind endovascularis módon kezeltek.

BACKGROUND: Traumatic intracranial aneurysms are rare, making up about 1% of all intracranial aneurysms. They can happen due to direct injury or blunt force, with the middle cerebral artery being the most frequent site. The middle meningeal artery (MMA) is the main artery that supplies the cranial dura mater, and, because of its location, is susceptible to damage after trauma. This article reported an unusual case of giant post-traumatic MMA pseudoaneurysm.
METHODS: A 45 year-old man was referred to our department with a history of craniectomy. He complained of non-specific headache, but neurological examination was normal. A follow-up brain CT scan identified a right temporal fossa hyperdense mass. Digital subtraction angiography diagnosed a traumatic MMA aneurysm. The patient was treated with preoperative aneurysm embolization and surgical resection.
CONCLUSIONS: Traumatic MMA aneurysm is a rare presentation after head trauma. It can manifest as epidural hematoma, subdural hematoma or intraparenchymal hematoma, and sometimes resembles the present case, which was discovered incidentally.
CONCLUSIONS: Pseudoaneurysm is a rare complication of MMA trauma, with late presentation. It should be considered in patients with history of traumatic brain injury and temporal fossa extra-axial mass lesion with vascular characteristics.

BACKGROUND: Unilateral biportal endoscopy (UBE) has been widely and skillfully used in the treatment of lumbar disc herniation and spinal canal stenosis. UBE surgery also brings some complications, such as dural tear, epidural hematoma, residual nucleus pulposus, etc. And we found a rare case of arachnoid cyst after UBE.
METHODS: A 48 years old female who had a history of cholecystectomy, nephrolithiasis, hyperthyroidism, chronic atrophic gastritis, and colonic polyps with several years of low back pain and numbness in both lower limbs was found have arachnoid cyst 3 years after UBE operation. We hope that we can give a new aspect of complication after the UBE treatment in the future.
CONCLUSIONS: We believe that the postoperative hypertension and the lack of postoperative back muscle strength training and some personal factors are the possible reasons for the arachnoid cyst in this case.

OBJECTIVE: To report a rare case of spontaneous bilateral epidural hematoma (EDH) in a 10-year-old Nigerian child with sickle cell disease (SCD) and review the literature regarding this unusual complication.
METHODS: We present a case of a pediatric patient with SCD who developed a spontaneous bilateral EDH and discuss the potential underlying mechanisms, management approaches, and outcomes. We also conducted a literature review of existing cases of spontaneous EDH in patients with SCD.
RESULTS: Our patient initially presented with a subgaleal hematoma and underlying bilateral EDH, but she was sent home without any neurosurgical consultation. Two years later, she returned with altered consciousness and left-sided weakness, revealing an increased size of the EDH with a noticeable mass effect. She underwent a successful emergency bilateral craniotomy, with noticeable improvement in her level of consciousness and left-sided weakness post-operatively. In our literature review, we found 40 reported cases of spontaneous EDH in SCD patients, with a male predominance (82.5%). The average age of patients was 15.282 years. The most common hematoma location was bifrontal (20%) and the most reported symptom was headache (47.5%). Most patients (97.5%) were already known cases of SCD. Among those treated, 77.5% survived.
CONCLUSIONS: Spontaneous bilateral EDH in SCD patients is an uncommon complication, with a variety of proposed pathophysiological mechanisms. Prompt recognition and appropriate management, either conservative or surgical, are crucial to improve outcomes. Our case and literature review underscore the importance of considering spontaneous EDH in SCD patients presenting with neurological symptoms, even in the absence of trauma. Further research is needed to elucidate the precise etiology, identify risk factors, and optimize management approaches for this rare complication in SCD patients.

BACKGROUND: Cervical epidural hematoma (CEH) is defined as a collection of blood in the suprameningeal space. Mechanisms of this rare pathology include spontaneous, postsurgical, and traumatic as the main subtypes. This unique case of traumatic CEH represents an even smaller subset of these cases. Management varies by symptom presentation, mechanism of injury, and other contraindications.
METHODS: This case presents a 32 year old African American female on an oral anticoagulant sustaining traumatic cervical hematoma after a motor vehicle collision. Patient complained of neck, abdominal, and back pain. Imaging revealed a cervical spinal hematoma at the level of C3-C6. This case discusses the management of CEH for the general population and in the setting of anticoagulation.
CONCLUSIONS: Management of each case of CEH must be carefully considered and tailored based on their symptom presentation and progression of disease. As the use of anticoagulation including factor Xa inhibitors becomes more prevalent, there is greater need to understand the detailed pathophysiological aspect of the injuries. Targeted reversal agents such as Prothrombin Concentrate can be used for conservative treatment. Adjunct testing such as thromboelastogram can be used to help guide management.

Introduction: Postoperative epidural hematomas of the cervical and thoracic spine can pose a great risk of rapid neurological impairment and sometimes require immediate decompressive surgery. Case Report: We present the case of a young patient operated on for stabilization of a two-level thoracic vertebra fracture who developed total paralysis due to an epidural hematoma postoperatively. The course of epidural hematoma was quickly reversed with the help of a conservative technique that prevented revision surgery. The patient regained complete neurologic function very rapidly, and has been well on every follow-up to date. Conclusion: There is a role of similar maneuvers as described in this case to be employed in the management of postoperative epidural hematomas. However, prolonged watchful waiting should still be discouraged, and patients should remain ready for revision surgery if there are no early signs of rapid recovery.

BACKGROUND: Gorham-Stout disease (GSD) is a rare disease that causes massive osteolysis and proliferation of abnormal lymphangiomatous tissues. Patients with GSD often experience pain associated with bone fractures and chylothorax. However, bleeding caused by abnormal lymphangiomatous tissue or hematological dysfunction rarely occurs.
METHODS: A 22-year-old female patient with GSD presented with severe left hip and lower limb pain. The GSD had disappeared her right pelvic bone and femur, but no abnormalities were found in the bones at the site of the pain.
METHODS: The patient presented with a chylothorax and cerebrospinal fluid leakage. She was treated with sirolimus and an epidural blood patch, and her symptoms resolved. Computed tomography and magnetic resonance imaging revealed an epidural hematoma extending from L3 to the caudal region, and blood results revealed a consumption coagulopathy.
METHODS: We presumed that the hematoma caused pain and prescribed pregabalin and morphine. The pain gradually subsided.
RESULTS: An unexpected liver subcapsular hemorrhage occurred 4 months later, and the patient went into hemorrhagic shock. Transcatheter arterial embolization was promptly performed, and the patient recovered.
CONCLUSIONS: GSD infrequently causes bleeding related to abnormal lymphangiomatous tissues and coagulopathy, yet it can lead to serious events if it occurs.

BACKGROUND: Ischemic monomelic neuropathy (IMN) is a disease that occurs after acute arterial occlusion or steal phenomenon in an extremity that results in single or multiple axonal mononeuropathies in the distal limb without the classical features of limb ischemia, including a skin color change, limb swelling, and ischemic claudication. IMN can easily be misdiagnosed as any other neuropathic disorder. Here we present a case of IMN that was misdiagnosed as spinal epidural hematoma.
METHODS: A 77-year-old man presented with sudden motor weakness and pain in his left foot and calf 5 days after a bilateral L4 to 5 posterior decompression for lumbar spinal stenosis. His symptoms progressed over the next 5 days. The strengths of the left ankle dorsiflexors, first toe extensors, and ankle plantar flexors were Medical Research Council 0. On brain and whole-spine magnetic resonance imaging, no specific abnormalities correlated with his symptoms were observed. Computed tomography angiography of the lower extremities revealed segmental occlusion of the left common femoral artery and multifocal severe stenoses in the bilateral anterior and posterior tibial arteries of the left leg. No skin color change or swelling was observed in the left lower extremity.
METHODS: Based on his clinical features and imaging findings, he was diagnosed with IMN.
METHODS: The patient underwent thrombectomy of the left femoral artery.
RESULTS: After the treatment, his pain almost completely disappeared.
CONCLUSIONS: When patients exhibit acute-onset pain in the unilateral limb with or without motor weakness but no correlated abnormality on spinal magnetic resonance imaging or computed tomography, clinicians should consider the possibility of IMN.

BACKGROUND: Multiple lumbar punctures have historically been a strategy to relieve headaches associated with idiopathic intracranial hypertension despite limited clinical evidence of long-term efficacy. Lumbar puncture is typically a straightforward procedure with minimal complications reported, however, serious complications can occur. Lumbar-puncture-related spinal hematomas are rare but can lead to irreversible paralysis.
METHODS: We report a case of a 28-year-old Caucasian woman who was treated with multiple lumbar punctures to manage headache, thought to be attributed to idiopathic intracranial hypertension. The patient developed a lumbosacral epidural hematoma following a lumbar puncture, which led to incomplete cauda equina syndrome. Multiple lumbar punctures had been the long-term management for the patient\'s chronic headaches associated with her diagnosis of idiopathic intracranial hypertension. She had no risks of an underlying coagulopathy. Following a lumbar puncture, she re-presented with lower back pain and bilateral paresthesia. Over the subsequent 48 hours, this progressed to urinary incontinence and saddle paresthesia. Imaging revealed an epidural hematoma, which was conservatively managed. She continued to report saddle paresthesia and urinary incontinence 7 months following the lumbar puncture. Between 1974 to 2022, our literature search found 41 case reports detailing lumbar-puncture-related spinal hematomas. It is an established but rare complication of lumbar puncture and there are limited studies looking at the incidence of its occurrence. Whilst coagulopathy has been found to be a risk factor, it is unclear if the gauge of the needle is relevant. Case evidence suggests there may be no significant difference in outcomes between surgical and conservative management of spinal hematomas. This case highlights that lumbar punctures can be invasive, with potentially serious complications. A lumbar puncture should therefore only be performed when clinically justified.
CONCLUSIONS: This case highlights a rare complication of lumbar puncture and emphasizes the importance of a risk-benefit discussion for each procedure. Spinal hematoma following lumbar puncture is a rare complication but with potentially devastating consequences. Within the setting of idiopathic intracranial hypertension, the evidence base for the long-term benefit of headache relief by repeat lumbar puncture is low.
