This is a case of LCA that was discovered incidentally in a 79-year-old woman who presented with a polycythemia at the time of consultation. The neoplasm was evaluated by ultrasound and computed tomography. The patient underwent a splenectomy that revealed LCA by pathological evaluation. The post-operative outcome was favorable with no complications or recurrent disease. This case presentation, clinical, radiographic, and pathological features of an uncommon splenic tumor can be studied in order to advance our knowledge in our understanding of LCA.展开更多

It has heretofore been described primarily in pathologic series and has been found mostly to behave as a benign entity. A few reports of malignant variants have been reported. We present a case report of a solitary LCA discovered after splenectomy for an incidentally discovered splenic lesion, along with a literature review.展开更多

We report a case of LCA of the spleen, which has been infrequently communicated in the literature. A 76-year-old man with a 2-wk history of weight loss, abdominal pain and changes in bowel habits was admitted to our hospital. Imaging studies （CT and MR1） showed multiple lesions in the spleen. Splenectomy was performed. Lining cells were positive for CD31/CD68 markers. Our case was associated with a serrated colonic adenoma. LCA is a benign vascular tumor of the spleen that needs to be included in the differential diagnosis of multiple splenic nodules.展开更多

MRI characteristic of spinal cavernous angiomas was just like popcorn or mulberry with a jumbled gobbet signal. Low and short T 2 signal appeared around the focus. In all cases, there were no obvious contrast enhanced signal in 2 cases and one case with moderate contrast enhanced signal. The diameter of hemorrhage was smaller than that of the spinal cord.Conclusion MRI has higher sensitivity and specificity in the diagnosis of spinal cavernous angioma.展开更多

In fact, we know only about two documented frontal lobe mass lesions—meningiomas, associated with torticollis. Our observation of frontal lobe cavernous angioma associated with clinical picture of torticollis confirms the role this area could play in the pathophysiology of involuntary movements. We report a case of patient with torticollis associated with cavernous angioma of the right frontal lobe and presuppose causative role of angioma in the development of our patient’s torticollis.展开更多

The term “giant cerebral cavernous malformations” still does not have a clear definition in the literature, with a wide variety of results. It is known, however, that there is an association between the size of the cavernoma and postoperative sequelae, especially in those with a size greater than 3 cm in its largest diameter. We present a case report of resection of a giant brain cavernoma measuring approximately 8 cm in its largest diameter, emphasizing on clinical presentation, diagnoses and postoperative evolution. Additionally, we performed a comprehensive review of the existing literature on the subject, addressing the epidemiology, pathophysiology, diagnostic methods, treatment options, and prognosis associated with this condition.展开更多
