Medulloblastoma is the most common malignant tumor of childhood and usually arises from the cerebellar vermis. Several histological types of medulloblastoma have been described. Myogenic and melanotic differentiated medulloblastoma are seldom seen. ⋯ According to our knowledge there are six cases reported in the literature so far. Oncogenic factors in medulloblastoma development are controversial. Presence of multiple differentiation patterns supports a pluripotent origin for these tumors.

To assess the long-term outcomes of percutaneous retrogasserian glycerol rhizotomy (PRGR) in patients with medically unresponsive idiopathic trigeminal neuralgia. ⋯ PRGR is a minimally invasive and simple procedure yielding a favorable outcome for trigeminal neuralgia. The major complications of this procedure are reversible within various time intervals. It may serve as a first-line surgical modality for patients unresponsive to pharmacotherapy.

Case Reports
Recurrent cerebral arteriovenous malformation with a posterior inferior cerebellar artery aneurysm.
Cerebral arteriovenous malformations (AVMs) are congenital lesions which rarely recur after complete microsurgical excision. ⋯ Although some authors do not propose routine additional follow-up in adults after the initial negative postoperative angiogram, we believe that such patients should be followed clinically and radiologically.

Pseudoaneurysms of the superficial temporal artery are mostly traumatic in origin. Here, a case of a superficial temporal artery aneurysm that emerged following a recraniotomy is presented. A 59-year-old woman was admitted with subarachnoid hemorrhage. ⋯ The pseudoaneurysm was excised successfully under local anesthesia. In conclusion, pseudoaneurysm of the superficial temporal artery should be considered among the early postoperative complications of the surgical procedures at the superficial temporal artery territory. Although some conservative approaches are used, excision of the aneurysm is recommended for treatment.

Clinical Trial
Simple decompression of the ulnar nerve at the elbow via proximal and distal mini skin incisions.
The purpose of the present study was to describe a new minimally invasive surgical technique for decompression of the ulnar nerve at the elbow for treatment of cubital tunnel syndrome. Four patients underwent surgical treatment for cubital tunnel syndrome. Preoperative clinical states were classified by using the McGowan grading system and the postoperative states were recorded by using the Wilson and Krout grading system. ⋯ At the last follow-up, three patients were recorded as excellent and one patient was recorded as good according to Wilson and Krout grading system. One patient showed improvement in sensory nerve conduction velocity another showed improvement in motor nerve conduction velocity at the last follow-up. We conclude that simple decompression of the ulnar nerve at elbow via proximal and distal mini skin incisions is an effective, technically simple and safe surgical method in the treatment of cubital tunnel syndrome.
