Ruptured aneurysm at an anastomotic artery extending from the vertebral artery to the posterior inferior cerebellar artery: a case report.

A 51-year-old hypertensive man presented with subarachnoid haemorrhage. He had a past history of cerebellar infarction due to occlusion of the right posterior inferior cerebellar artery (PICA) 4 years earlier. Digital subtraction angiography showed a saccular aneurysm above an arterial loop extending from the vertebral artery to the distal part of the PICA, reminiscent of peripheral PICA branches.

Successful treatment of intraorbital lymphangioma with tissue fibrin glue.

Background: Although surgical resection is the first treatment choice in patients with cystic lymphangioma, the complete resection of orbital lymphangioma is often difficult. After partial resection of the cyst wall, some cystic lymphangiomas recur. The injection of tissue fibrin glue may prevent the recurrence of orbital lymphangioma.
