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.

Stereo-electroencephalography (SEEG) is an invasive procedure, used to identify the epileptogenic zone that can be surgically removed in order to treat drug-resistant epilepsy. Frameless robot-assisted positioning of depth electrodes permits a 3D approach with different obliquities and trajectories. The objective of the present study was to evaluate the morbidity and the accuracy related to this frameless procedure. ⋯ Frameless robot-assisted SEEG appears to be a safe procedure, providing sufficient accuracy in order to delineate the epileptogenic zone and represents a helpful tool in the pre-surgical management of refractory epilepsy.
