Diagnosis and management of liver abscesses in low- and middle-income countries (LMICs) is difficult due to limited diagnostic imaging availability. Limited data is available describing the use of point-of-care ultrasound (POCUS) in the diagnosis and percutaneous aspiration of liver abscesses in resource-limited countries. We describe a 21-year-old female who was diagnosed with a liver abscess. The diagnosis of liver abscess was made via POCUS, and the patient was successfully managed with empiric antimicrobials and repeated POCUS-assisted percutaneous needle aspiration. In resource-limited settings, adequate training of personnel and availability of POCUS may help in early diagnosis and treatment of liver abscess - thus helping to reduce its related morbidity and mortality - while also aiding in resource conservation.

We describe a rare and remarkable transformation of an immature mediastinal teratoma into high-grade angiosarcoma in a 21-year-old male. Mediastinal teratomas, particularly immature ones, are exceedingly rare, representing a small fraction of germ cell tumors (GCTs). Our case describes the clinical journey of the patient, who initially presented with acute chest pain and was subsequently diagnosed with an immature teratoma following imaging studies and elevated tumor markers. Despite an initial positive response to cisplatin-based chemotherapy, surveillance imaging revealed liver masses, which a biopsy confirmed as angiosarcoma. This transformation underscores the aggressive nature of immature teratomas and the propensity for sarcomatous differentiation, particularly in the mediastinum. The case contributes valuable insight into the management and surveillance of mediastinal non-seminoma germ cell tumors (MNGCT), a subset of GCTs with limited literature. We believe this case is the first in the literature to describe a transformation from an immature teratoma in the mediastinum to a high-grade angiosarcoma.

Stroke mimics are difficult to differentiate from each other. Symptomatic epilepsy can also occur, but it is necessary to perform a magnetic resonance imaging (MRI) scan to distinguish it from a stroke. Although respiratory acidosis has been reported to occur with partial-onset seizures due to prolonged apnea, respiratory acidosis is rarely suspected to be a sign of epilepsy. We report a case in which respiratory acidosis helped to diagnose symptomatic epilepsy with stroke mimics. The patient was a 52-year-old female who was brought to the emergency room with the chief complaint of difficulty in talking. When she visited the hospital, sensory aphasia was observed, and a computed tomography (CT) scan was performed. She vomited after the CT scan, and an arterial blood gas analysis showed a pH of 7.26 with a PaCO2 level of 71 mmHg, indicating respiratory acidosis. After the administration of diazepam, the seizures abated and her sensory aphasia improved. Later, an investigation of the patient\'s history revealed symptomatic epilepsy and discontinuation of antiepileptic drugs. If unexplained respiratory acidosis is noted in a patient with stroke mimics, a further investigation of the patient\'s history and physical examination may help to diagnose symptomatic epilepsy.

There are increasing reports of the effects of COVID-19 on the pancreas. Pancreatitis, as a result of hypertriglyceridemia, has also been reported. Hypothesized mechanisms include hemophagocytic lymphohistiocytosis (HLH) syndrome and acquired lipoprotein lipase (LPL) inhibitors. We present a 51-year-old female patient who presented with nausea, vomiting, and epigastric abdominal pain radiating to the back. On examination, she had generalized abdominal tenderness without guarding or rebound tenderness. Our workup revealed elevated lipase of 1150 units/L, triglycerides (TG) of 11340 mg/dL, and mild pancreatitis on an abdominal computed tomography (CT) scan. On day 2, she developed a new oxygen requirement and tested positive for COVID-19. She was treated with fluids and opiates for pancreatitis, plasmapheresis, and an insulin infusion to treat her hypertriglyceridemia. She was treated with remdesivir for an acute COVID-19 infection. Triglycerides decreased to <500 mg/dL with treatment, and she was discharged home on oral lipid-lowering agents. By discussing this case, we aim to shed light on the association between COVID-19 and hypertriglyceridemia, which can further lead to life-threatening complications such as acute pancreatitis. Further studies are needed to identify the exact mechanisms, preventive measures, and long-term effects of COVID-19 on triglycerides and the pancreas.

Lipomas are benign soft tissue tumors that are ubiquitous in nature. Available literature suggests that benign tumors are harmless unless they increase in size, resulting in compression of vital structures. This case report discusses the case of a 52-year-old man who presented to the clinic with a painless, growing lump on the right side of his mouth. The patient\'s symptoms included difficulty swallowing and speaking, which led the doctors to recommend surgical excision of the mass. There were no issues during the mass removal surgery, and the incision healed without compromising the lingual or hypoglossal nerves or Wharton\'s duct, as observed during follow-up visits. Patient history, symptoms, preoperative examination, treatment strategy, and surgical technique are all included in this case study, which focuses on the extremely unusual development of lipomas in the oral cavity, particularly on the floor of the mouth.

Cerebral arteriovenous malformations (cAVMs) are developmental pathologic lesions of the blood vessels of the brain in which multiple arteries shunt blood directly into the venous drainage network. They are lesions with an unclear etiology and, if left untreated, can bear significant risks of complications such as migraines, seizures, neurological deficits, and intracranial hemorrhages. The diagnosis is based on several imaging methods, with angiography being the primary method. Treatment modalities include microsurgery, radiosurgery, embolization with the intent of obliteration, and various multidisciplinary approaches. We aim to introduce the case of an adult female patient with symptomatic cAVM who underwent partial endovascular embolization of the lesion and evaluate her recovery and the overall reliability of her treatment modality. A 22-year-old female patient has presented to the Neurosurgery Clinic with clinical manifestations with photosensitive seizures, migraines, and a history of sleep disturbances persisting for a period of one year. An appointed MRI and angiography revealed the presence of a glomerular cAVM of the anterior parietal branch of the middle cerebral artery located within the intraparietal sulcus of the left cerebral hemisphere (Spetzler-Martin grade 2). The venous drainage of the malformation led to a loss of nutrients in the surrounding brain parenchyma (a steal phenomenon), causing the seizures. The patient successfully underwent transarterial endovascular embolization with Onyx, which proved to be partial on a postoperative angiography, and refused further embolization procedures. There were no postoperative complications to be mentioned. The patient reported no seizures or sleep disturbances at the 12-month follow-up, with sporadic weak headaches remaining. cAVMs remain a pathology with significant morbidity and mortality when undiagnosed. Symptomatic cAVMs leading to a steal phenomenon and seizures can be reliably managed via endovascular embolization alone when the malformation has an appropriate angioarchitecture, location, size, and a low Spetzler-Martin score. However, further inquiry is required into the use of partial embolization in cases where further multiple-stage embolization procedures are declined and/or complete occlusion of the lesion is unfeasible. This case report emphasizes that partial endovascular embolization can be successfully utilized as a treatment modality for the symptoms caused by a steal phenomenon of the venous drainage of a cAVM, such as seizure disorders and migraines, in the rare instance when multiple-stage embolization is declined by the patient and occlusion of the lesion remains subtotal.

Perineural cysts, also known as Tarlov cysts, are rare benign cerebrospinal fluid-filled cysts usually located at the junction of the posterior nerve root and the dorsal root ganglion and are usually asymptomatic. They are most commonly found in the sacral region and are uncommon in the cervical spine. Despite their rarity, symptomatic cases may present with neurological symptoms due to the compression of adjacent neurological structures. Symptomatic cervical perineural cysts are extremely rare, and there is limited consensus on management strategies. We present the case of a 56-year-old woman who presented with a four-week history of radicular symptoms involving the right C7 and C8 nerve roots, including neck and arm pain, paresthesias, and mild triceps weakness. Magnetic resonance imaging revealed two perineural cysts at the C6-C7 and C7-T1 levels. A conservative approach was chosen with a 14-day course of oral corticosteroids, use of a soft collar, and activity restrictions. Following this conservative treatment, a significant reduction in symptoms and complete neurological recovery were achieved. This case highlights the efficacy of conservative approaches in selected cases of mildly symptomatic cervical perineural cysts and contributes to a better understanding of management strategies for this condition.

Chronic intestinal schistosomiasis (CIS) refers to the long-term effects of infection with Schistosoma parasites in the intestines. This condition typically develops after repeated or prolonged exposure to contaminated freshwater containing Schistosoma eggs. The current study reports a case of an adult male, who complained of abnormal abdominal and anal pain for a month and had a medical history of complex perianal fistulae. The endoscopic investigation revealed different degrees of hyperemia, concentrated in the sigmoid colon and rectum. Lesions were localized in the rectum and sigmoid colon. Yellow granular hyperplasia, whether concentrated or dispersed, single or multiple polyps, along with observations of mucosal congestion, edema, faint vascular striations, erosions, superficial ulcers, and scattered petechial hemorrhages were noted. Also, the segmented areas of the colon had different degrees of inflammation. The microscopic histopathological analysis showed a culprit of surgical scar tissue. The granulomas harbored Schistosome parasites at the submucosal depth. Also, an erosion in the colonic mucosal tissues accompanied by lymphoplasmacytic and micro-abscess infiltrates was seen. A Schistosoma bilharzial ova was observed in the granuloma at the submucosal level. Endoscopic and histopathological investigations are useful tools to differentiate between CIS and Crohn\'s disease. These tools can distinguish CIS from Crohn\'s disease. Early detection and treatment are essential to prevent the progression of the disease and minimize long-term complications.

We report a case of a 31-year-old gravida 2 para 1 female presenting to the optician with a two-week history of blurred vision and persistent headaches at 29 weeks gestation. Visual acuity on presentation was 6/100 in the right eye and 6/24 in the left eye. Fundoscopy of both eyes revealed serous retinal detachment in the absence of background retinal changes. On urgent admission to the maternity assessment unit, blood pressure was 189/126 mmHg and urine dipstick revealed 4+ proteinuria. Due to recurrent poor foetal heart rate variability on cardiotocography monitoring, an emergency caesarean was conducted. Sixteen hours following delivery, visual symptoms had improved, and clinical examination revealed normal blood pressure. An optical coherence tomography scan performed three months later was dry bilaterally with minor retinal pigment epithelium clumping. Serous retinal detachment involves the separation of the neurosensory retinal layer from the underlying retinal pigment epithelium. It is rare in pre-eclampsia but can be seen in patients with severe disease. The presentation of serous retinal detachment includes acute visual loss, reduced visual acuity, floaters, and flashing lights appearing in the vision. Although alarming on initial presentation, resolution is commonly seen within a couple of days postpartum. The pathogenic mechanism for serous retinal detachment development is widely discussed and thought to include changes to the choroidal circulation. Overall, although often self-resolving, a move to thorough antenatal care and vigilant monitoring in pre-eclamptic women is vital to prevent complications like this from occurring.

The efficacy and optimal frequency of acupuncture for hemifacial spasms (HFSs) in patients unresponsive or averse to standard treatment methods remains unestablished. Here, we administered acupuncture to a patient with HFSs who was dissatisfied with the outcomes of botulinum toxin (BoNT) injections as symptomatic treatment. A man in his 60s, experiencing frequent spasms in his left facial muscles since 2015, had received several BoNT injections without receiving microvascular decompression or medication; however, the treatment results were not satisfactory. In 2020, he visited our clinic for acupuncture. His entire face twitched involuntarily, and the other Babinski sign was observed. The spasm severity was 5 on the numerical rating scale (NRS). Acupuncture was performed on the gallbladder meridian (GB) 2, stomach meridian (ST) 7, and triple energizer meridian(TE) 17 along the facial nerve and GB14, GB1, small intestine meridian (SI) 18, ST4, ST5, and ST9 on the affected (left) side. In the fourth session, 1 Hz electroacupuncture at ST7 and TE17 reduced the NRS score to 1. As his spasms were well managed, we initially continued with biweekly acupuncture sessions. However, by the 10th session, a worsening of symptoms led to a revert to weekly treatment, which maintained a decreased NRS score until the 21st session. Our findings suggest that weekly acupuncture may be a viable treatment modality for patients with HFSs unresponsive or averse to conventional treatments. Future prospective clinical trials are required to verify the efficacy of acupuncture for HFSs.
