We report the case of a woman nearing 70 years old who was admitted to the hospital with a complaint of \"epigastric distension for 1 month\". Her main signs and symptoms were progressive abdominal distension and occasional abdominal pain. Computed tomography suggested an abdominal mass. She had a surgical history of synovial sarcoma (SS) of the lungs. After admission, she was diagnosed with jejunal SS following a puncture biopsy and laparoscopic surgery. This disease usually occurs in the soft tissues of the limbs, and it is extremely rare for SS to originate in the jejunum. The morphologic heterogeneity of SS overlaps with other tumors and makes the diagnosis particularly difficult. Imaging studies usually lack specificity; however, measuring multiple immunohistochemical markers can greatly assist in the diagnosis and differential diagnosis of SS. This case not only enriches our understanding of SS and describes a rare site of origin, but also emphasizes the importance and challenges of achieving an accurate diagnosis. Immunohistochemical and molecular biological testing have important roles in the definitive diagnosis, highlighting the need for precise and innovative diagnostic and therapeutic approaches in SS.

BACKGROUND: Situs inversus with levocardia is a rare anomaly in which the heart is present in the left chest but the abdominal viscera are transposed. It is caused by a single incomplete penetration of an autosomal recessive gene. It is unclear what exactly causes situs inversus with levocardia. Even if situs inversus can be identified following a comprehensive physical examination, it is now possible to validate the results and search for further information and pathologies since medical imaging is so widely accessible.
METHODS: A 15-year-old Oromo male child from a remote area of Bale Zone presented to the Goba Referral Hospital\'s medical emergency outpatient department complaining of periumbilical pain that had persisted for 4 months. He frequently came to our hospital and was admitted three times with the same problem. Objectively, there was tenderness over the left lower quadrant and periumbilical area. The sonographic evaluation discovered the transposition of the liver and spleen with cardiac apex on the left side. He received conservative treatment with ceftriaxone 1 g intravenous twice a day and metronidazole 500 mg intravenous for 5 days, and he went home improved.
CONCLUSIONS: Isolated levocardia is a rare form of situs inversus in which the heart is in the traditional levo position while the abdominal organs are in the dextro position. What causes situs inversus with levocardia is unknown. Despite the fact that situs inversus can be diagnosed after a thorough physical examination, medical imaging has allowed us to confirm the findings as well as understand more about diseases. Due to the severity of an underlying heart defect, situs inversus with levocardia has a dismal prognosis.

BACKGROUND Extrahepatic and extrapulmonary localizations of cystic echinococcosis (CE) are rare and the incidence of splenic involvement is seen in 1.0% to 3.3% of all cases in the endemic areas of the Middle East and Asia. The diagnostic pathway consists of a detailed travel history, physical examination, abdominal ultrasonography, computed tomography, and serological tests. The efficacy of perioperative administration of albendazole (400 mg twice a day) has been proven; however, the appropriate surgical procedure for the treatment of giant, centrally located splenic hydatid cysts remains controversial. CASE REPORT We present the case of a 49-year-old woman referred to our hospital for a suspected isolated splenic hydatid cyst causing a compression of the right kidney, stomach, and the tail of the pancreas. She reported chronic pain in the left upper quadrant and a history of contact with animals. She underwent open splenectomy via a medial to lateral approach to minimize manipulation of the spleen. In addition, she received perioperative parasitostatic drug therapy with albendazole. The postoperative period was uneventful and the histologic analysis confirmed the diagnosis. CONCLUSIONS The spleen is a rare location for isolated CE, especially in non-endemic areas and must be considered in the differential diagnosis of splenic cystic masses. Surgical resection remains the most effective treatment that completely resolves this condition. A comparison of randomized trials is needed to compare the recurrence rates between splenectomy and spleen-preserving procedures in the treatment of giant splenic hydatid cysts.

BACKGROUND: Pedicle screws are durable and safe instruments frequently used to treat vertebra injuries and deformities. There is also a possibility of medulla spinalis and visceral organ injury when the pedicle screws are delivered in unsuitable positions or dimensions. In this case, the authors want to draw attention to one of the visceral organ injuries during the thoracic pedicle screw placement.
METHODS: A 31 years old man underwent posterior instrumentation and fusion for T4 vertebra fractures. The patient was not symptomatic in the postoperative period. Tracheal pressure was observed at the 3rd thoracic vertebra level on the second day after the operation. No complications were encountered in the 3-year follow-up of the patient, who did not accept a second surgery recommended for screw replacement.
CONCLUSIONS: During surgery for thoracic vertebral fractures, the shoulder joint makes it difficult to imagine as the shoulder bones enter the field of view. Therefore, the number of misplaced screws increases. Moreover, it increases the risk of internal organ injury.
CONCLUSIONS: The use of navigation systems or cannulated pedicle screws to treat thoracic vertebral fractures reduces internal organ injuries.

UNASSIGNED: Spontaneous multiple artery dissection is a relatively rare phenomenon. Early clinical signs are often nonspecific, making it difficult to diagnose.
UNASSIGNED: This is a case of a 51-year-old female who presented with spontaneous dissection of 4 visceral arteries, both iliac arteries, and of the right internal carotid artery. The patient underwent urgent successful endovascular repair. Later complications included acute respiratory distress syndrome and pneumonia after massive blood transfusion. She recovered gradually and was discharged after 21 days. Due to this rare presentation, genetic investigation was performed in search of a connective tissue disorder. Results revealed a new COL3A1 subtype mutation. The pathogenicity of this variant remains unclear.
UNASSIGNED: We recommend a high index of suspicion for visceral artery dissection in the differential diagnosis for abdominal pain with concurrent uncontrolled hypertension. Early diagnosis and intervention are crucial to reducing the mortality rate.

To evaluate the influence of a visceral protective layer (VPL) on the formation of enteroatmospheric fistulae (EAF) in open abdomen treatment (OAT) for peritonitis.
EAF formation is a severe complication of OAT. Despite the widespread use of OAT, there are no robust evidence-based recommendations for preventing EAF.
A total of 120 peritonitis patients with secondary peritonitis as a result of a perforation of a hollow viscus or anastomotic insufficiency who had undergone OAT were included, and 14 clinical parameters were recorded in prospective OAT databases at 2 tertiary referral centers. For this analysis, patients with a VPL were assigned to the treatment group and those without a VPL to the control group. Propensity Score (PS) matching was performed. Known risk factors in OAT such as malignant disease, mortality, emergency operation, OAT duration, and fascial closure were matching variables. The influence of VPL on EAF formation was statistically evaluated using logistic regression analysis.
With 34 patients in each group, no notable differences were identified with regard to age, sex, underlying disease, mortality, emergency operation, fascial closure, and OAT duration. Overall, a mortality rate of 22.1% for OAT due to peritonitis was observed. Mean OAT duration was approximately 9 days, and secondary fascial closure was achieved in more than two-thirds of all patients. Fascial traction was used in more than 75% of cases. EAF formation was significantly more frequent in the control group (EAF formation: VPL group 2.9% vs control 26.5%; P = 0.00). In the final regression analysis, the use of VPL resulted in a significant reduction in the risk of EAF formation (odds ratio 0.08; 95% confidence interval 0.01-0.71, P = 0.02), which translates to a relative risk reduction of 89.1%.
VPL effectively prevents EAF formation during OAT in patients with peritonitis. We recommend the consistent use of VPL as part of a standardized OAT treatment algorithm.

BACKGROUND: We present a case with multiple visceral artery aneurysms that were treated with a hybrid approach involving both surgical and endovascular treatment.
METHODS: The patient was a 48-year-old female. She was diagnosed with multiple visceral artery aneurysms including 2 splenic artery aneurysms, celiac artery aneurysm, and bilateral renal artery aneurysms during an examination for loss of appetite. With regard to 2 splenic artery aneurysms, the proximal aneurysm was treated surgically, whereas the peripheral aneurysm that was located deeply in the abdomen was treated with coil embolization. The celiac artery aneurysm located at the bifurcation of the common hepatic artery and splenic artery, an intracranial aneurysm clip was used. The left and right renal aneurysms were resected and renal arteries were reconstructed surgically. The postoperative course was uneventful. The pathological diagnosis of all aneurysms was segmental arterial mediolysis. The reconstructed vessels were patent without stenosis or recurrence at 1 year after the operation.
CONCLUSIONS: Hybrid treatment involving surgical resection, endovascular coil embolization, and obliteration with clips was useful in the treatment of multiple visceral artery aneurysms.

Visceral angioedema is a rarely reported side effect of angiotensin-converting-enzyme inhibitors (ACEI). Because signs and symptoms tend to be nonspecific, the diagnosis is difficult to make, especially in the emergency department (ED).
We describe 2 patients presenting with signs of hypovolemic shock, in which the diagnosis of ACEI-induced visceral angioedema was made in the ED. We surmise that patients with abdominal pain, who present with hypovolemic shock and are taking medications that can predispose to angioedema, may have this complication if their hemoglobin level is elevated compared with their previous levels. An abdominal computed tomography scan, if it does not identify any other significant etiology, will increase the probability that ACEI-induced visceral angioedema is the diagnosis when there is nonspecific bowel wall thickening or edema. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Identification of ACEI-induced visceral angioedema in the ED will avoid prolonged admissions, unnecessary procedures, and future recurrences.
