Cavernous-carotid artery (CCA) aneurysms represent about 3-5% of all intracranial aneurysms. Spontaneous thrombosis of a CCA aneurysm with simultaneous occlusion of its parent vessel is an extremely rare phenomenon with few reported cases in the literature offering different management strategies. A 54-year-old Asian female presented with a one day-history of painless left eye conjunctival injection, proptosis, and features of cavernous sinus syndrome (cranial nerve III, IV, V1, V2, and VI palsies). Imaging revealed a giant thrombosed CCA aneurysm measuring 3.6cmx3.4cm with complete thrombosis of the left cervical internal carotid artery (ICA) and adequate collaterals from the anterior and posterior communicating artery and branches of the left external carotid artery. Management was conservative with antiplatelet therapy and close clinical-radiological follow-ups. The outcome was satisfactory. Data in the literature on this condition is limited due to its exceedingly rare occurrence. The majority of patients do well via a conservative approach and surgery is rarely indicated. For clinically stable patients, especially those with adequate collateral circulation and tolerance to Balloon Test Occlusion, we advocate for a conservative approach and initiation of anti-platelet therapy to treat these patients. Emphasis is needed on close serial clinicalradiological surveillance in these cases to monitor the propagation of the thrombus as well as the development of new and/or enlarging pre-existing aneurysms in the contralateral ICA circulation.
Background Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the alimentary tract. They are usually manifested by GI bleeding.
Case Presentation A 53-year-old male patient was admitted to the hospital for elective inguinal hernia repair. The patient did not have any history of GI symptoms in the past. A day after open inguinal hernia repair, the patient developed recurrent attacks of hematemesis resulting in hemodynamic instability and admission to the intensive care unit. An upper GI endoscopy identified a small bleeding gastric lesion. After multiple failed attempts to control the bleeding endoscopically, an emergency exploratory laparotomy was performed. An unexpected large fungating bleeding gastric mass was detected. The mass measured approximately 40 × 30 cm, and multiple peritoneal deposits were also discovered. A wedge resection of the anterior gastric wall along with the mass was performed. Histopathology revealed a high-grade (G2) GIST.
Discussion GISTs appear in variable sizes and may lead to a variety of complications including abdominal pain, GI obstruction, and bleeding. This case highlights the unexpected presentation and sudden bleeding of a large GIST in a totally asymptomatic patient undergoing elective hernia surgery. It also illustrates that GIST can be asymptomatic and grow to large sizes before developing clinical manifestations.
Conclusion The case report highlights a common complication of GIST with unexpected timing, immediately after routine hernia surgery.
Introduction: Extraskeletal Ewing’s sarcoma (EES) is a rare malignant soft tissue tumor. Those aggressive mesenchymal tumors are characterized by genetic alterations of the Ewing sarcoma gene (EWS) on chromosome 22. Signs and symptoms are usually non-specific. The clinical diagnosis of EES is challenging.
Case Presentation: A 31-year-old female patient presented to our hospital with rectal bleeding. Physical examination revealed a painful and erythematous bleeding rectal mass. A pelvic MRI revealed a right-sided well-circumscribed perianal mass measuring 6.8 × 6.0 cm. Surgical excision of the rectal mass was subsequently performed. The resected specimen, including the rectal mass with a pedicle from the posterior rectal wall was sent for histopathological examination. The postoperative period was uneventful. Histopathology examination was suggestive of EES of the rectum.
Clinical Discussion: EES is an unusual entity of Ewing's Sarcoma Family of Tumors, which are characterized by pathognomonic translocations. The clinical features of EES include localized pain and/or swelling. Diagnosis of EES relies on histopathology and immunohistochemistry analysis. Imaging modalities such as CT, MRI, and PET/CT are crucial to evaluate EES metastasis and assess local tumor resectability.
Conclusion: Due to the rare entity of EES of the rectum, we report the case of a 31-year-old female with rectal bleeding, found to be rectal Ewing’s sarcoma.
