Review Case Reports
Distal superior cerebellar artery aneurysm in a patient with systemic lupus erythematosus: case report.
The authors describe a case of ruptured distal superior cerebellar artery (SCA) aneurysm in a patient with systemic lupus erythematosus (SLE). ⋯ Aneurysms arising from peripheral segments of cerebellar arteries are rare, and delayed surgical clipping has been recommended for these lesions. In addition, the outcomes of SLE patients with ruptured cerebral aneurysms are reported to be very poor due to the systemic complications of SLE. However, our patient had a favorable outcome with early endovascular treatment for the ruptured aneurysm and with appropriate medical treatment for the accompanying SLE. Therefore, early endovascular coil embolization is worthy of consideration among the options for therapeutic intervention in these conditions.

Review Case Reports
Intradiploic hematoma after skull fracture: case report and literature review.
Intradiploic hematoma of the skull was first reported in 1934. The pathogenesis of this lesion is unclear. It is a very rare benign reactive process occurring after minor head trauma, with only seven cases reported in the literature to date. ⋯ The pathology of chronic diploic hematoma mimics aneurysmal bone cyst, giant cell tumor, giant cell reparative granuloma, fibrous dysplasia, eosinophilic granuloma, intradiploic epidermoid and dermoid cyst, cavernous hemangioma, circumscribed osteomyelitis, and tuberculous granuloma. Chronic diploic hematoma is a lesion that must be differentiated from various skull lesions both radiologically and histologically as it is amenable to treatment with a complete cure once excised.

The present study describes the use of a limited subtemporal extradural anterior petrosectomy with preoperative embolization of the inferior petrosal sinus for the management of tumors located behind the clivus and ventral to the brainstem. Details of the procedure and its application in five cases are presented. ⋯ Quite easy to master, the anterior petrosectomy with preoperative embolization of the inferior petrosal sinus is a time-conserving approach giving one of the best routes to reach the ventral brainstem while working in front of the cranial nerves and preserving hearing.

Meralgia paresthetica, a syndrome of pain and/or dysesthesia in the anterolateral thigh, is normally caused by an entrapment of the lateral femoral cutaneous nerve (LFCN) at the anterior superior iliac spine. In a few cases compression of the nerve in the retroperitoneum has been reported to mimic meralgia paresthetica. ⋯ In patients with meralgia paresthetica we emphasize a complete radiological investigation of the lumbar spine, including MRI, to exclude radicular compression by a disc herniation or a tumour at the level of L2 or L3.
