AbstractRete MCA anomaly is extremely rare and has been seldomly discussed in literature. Embryologically MCA develops by fusion of multiple twigs which form a single channel. If there is failure to fuse a plexiform network of vessels persists known as rete MCA. This web like network of vessels is at high risk of haemorrhagic stroke and therefore for patients presenting incidentally correct diagnosis is paramount. Here we report a case of rete MCA anomaly in a 35-year-old gentle man who presented with a large haemorrhagic stroke in emergency. DSA showed unilateral involvement of proximal MCA, and otherwise normal intra-cranial vasculature. With this report we aim to correctly diagnose this rare condition and avoid misdiagnosis leading to unnecessary treatments.
Cerebral metastasis occur in 10 to 20% of patients with choriocarcinoma. We describe the twelfth patient with oncotic aneurysms from choriocarcinoma verified by cerebral angiography. The importance to consider this disease in a woman of childbearing age who develop an intracerebral hemorrhage or a lesion with mass effect is emphasized, as well as laboratorial and radiological characteristics. Therapeutic approaches with chemotherapic agents, surgery and irradiation are discussed.
