Review Case Reports
Masson's tumor revealed by an intracerebral hematoma. Case report and a review of the literature.
We report the case of a 56-year-old woman who underwent total resection of a Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH), which was discovered due to a left temporal intracerebral hematoma revealed by aphasia. IPEH is more often localized on cutaneous and subcutaneous locations, intracranial IPEH are rare and only approximately twenty cases have been published to date. These tumors are a benign vascular lesion composed of papillary intravascular proliferation of epithelial cellular associated thrombosis with fibrin deposits responsible for vascular lumen obliteration. ⋯ The age of discovery is between 12 and 70 with a female predominance. IPEH are often localized close to the venous sinus or can be developed in a vascular malformation, thrombus or aneurysm. The curative treatment is total resection but recurrence has been reported, long-term follow-up with MRI is recommended.
