Intracranial thrombosed anastomosing hemangioma: Case report

Abstract

An anastomosing hemangioma is a relatively new diagnosis of a benign vascular lesion that is typically found in the genitourinary tract. On imaging, anastomosing hemangiomas have a broad differential diagnosis and can resemble malignant lesions such as angiosarcoma. Here we present a case of a 33‐year‐old male with seizures who on imaging was found to have a presumed recurrent intracranial meningioma. After surgical resection of his lesion, this case was pathologically diagnosed as having anastomosing hemangioma. To our knowledge, this is the first report of a case of a thrombosed anastomosing hemangioma located at intracranial and intradural region.

Imaging findings of retroperitoneal anastomosing hemangioma: a case report and literature review

“…Unfortunately, the studies that have reported tumor capsules did not show imaging findings. Its shape can be roundish or irregular with lobulation [ 18 , 20 ]. Furthermore, the internal density is uneven, and only a few cases have demonstrated the presence of fat or calcification [ 7 , 21 ].…”

Hepatic anastomosing hemangioma: description of a rare case and a literature analysis

“…Our present case showed tumor enlargement during follow-up at a growth rate of 3.6 mm per year. AHs in other sites (soft tissue, kidney, intracranial) exhibited varied growth dynamics, from remaining stable to growing rapidly ( 19 , 20 ). A previous study indicated that almost 40% of conventional hepatic hemangiomas increased in size over time with an overall rate of 0.3–2 mm per year in diameter ( 21 ).…”
