Case ReportsBehçet's disease with ruptured anterior communicating artery aneurysm following ruptured thoracic aortic aneurysm.
A 48-year-old Japanese woman with Behçet's disease suffered successive rupture of thoracic aortic and cerebral aneurysms within one year. The patient underwent successful surgical treatment for both aneurysms. Histological examination of the aneurysm walls revealed lymphocyte infiltration into the adventitia with smooth muscle cell hyperplasia in the thickened intima. This is an extremely unusual presentation of Behçet's disease associated with both cerebral and aortic aneurysms.

Case ReportsPosterolateral sulcus approach for spinal intramedullary tumor of lateral location: technical note.
Posterolateral sulcus (PLS) approach of the spinal cord, being equivalent to the dorsal root entry zone myelotomy, may offer the satisfactory exposure of the spinal intramedullary tumor if applied appropriately. Eight consecutive patients with spinal intramedullary tumors of lateral location underwent the surgery of PLS approach in our institute. There were 6 male and 2 female patients, ranging in age from 34 to 72 years (mean, 57 years). ⋯ Average grade of the sensory pain scale was 2.7 before surgery and improved to 1.7 at 3 months after surgery. PLS approach can be one of the surgical choices to the spinal intramedullary tumors, if applied appropriately. Better indication for PLS approach may be the tumors of the uneven location within the spinal cord associated with moderate or severe local pain.

A 34-year-old female presented with trigeminal neuralgia caused by a venous malformation in the right cerebello-pontine region. Computed tomography and magnetic resonance imaging demonstrated the abnormal draining veins from the venous malformation. The dilated vessels extended around the trigeminal nerve and compressed the root entry zone. ⋯ Good outcome depends on decompression of the root entry zone without injury to the vessel. Surgical injury in this region can cause severe neurological deficits. Several treatment options should be prepared for the surgery, such as MVD or rhizotomy.
