Epidural metastasis of testicular yolk sac tumor: an unusual cause of spinal cord compression. Case report.

Testicular tumors in the pediatric age group are rare. Yolk sac tumor (YST) is the most common malignant tumor of germinal origin in this group, and it may spread to the retroperitoneal lymph nodes. We have been unable to find any previously published report of metastasis of testicular YST to the epidural space of the spinal cord presenting as a cause of spinal cord compression.

Bilateral subpleural ectopic brain tissue in a 23-week-old fetus.

Bilateral lesions were seen in the subpleural region in a 23-week-old aborted male fetus. This fetus was not macerated and showed no central nervous system abnormality on physical examination and vertebral magnetic resonance imaging (MRI). Postmortem examination revealed bilateral, paravertebral, subpleural, circumscribed, yellowish-white, fluent lesions 2.5 x 1 x 1 cm in size. These lesions were localized on the upper part of both lungs and there was no other internal malformation. Histological examination of lesions showed adult neurones and well-differentiated neural tissue with white and gray matter, choroid plexus, ependymal structures and, rarely, some peripheral neural cells in addition to immature neuroectodermal cells. These cells were more mature than those in the brain tissue.

Meckel Gruber syndrome: a case diagnosed in utero.

A case of Meckel Gruber syndrome is presented, diagnosed prenatally from the medical history of the mother which revealed a previous malformed stillborn with anencephaly, meningomyelocele, polydactyly and ambiguous genitalia. This was the first prenatally diagnosed case ever reported in Turkey. The clinical, computed tomography and postmortem findings and the related literature are reviewed.

Nonsuture closure of arterial defect by vein graft using isobutyl-2-cyanoacrylate as a tissue adhesive.

Nonsuture repair of intracranial blood vessel is still a challenging issue in neurosurgery. In this experimental study isobutyl-2-cyanoacrylate was used for nonsuture repairing of carotid artery to observe its histotoxicity. Isobutyl-2-cyanoacrylate was dropped over the edge of defect on carotid artery of rat under the surgical microscope and jugular vein was placed to cover the defect. Rats were divided in 6 group according to postoperative survival period (2, 5, 7, 14, 21, 28 days respectively). The carotid arteries were patent of all rats according to angiography and autopsy specimen. Histopathological results showed that: the changes are mainly inflammatory respons +, there was no necrotic tissue at any time the healing progress and no significant differences in the vein graft. Therefore isobutyl-2-cyanoacrylate is considered helpful and safe adhesive material for the nonsuture repair of blood vessel.

Acoustic neurinoma with intratumoral bleeding.

The Authors present a case of acoustic neurinoma which has caused intratumoral bleeding. Although acoustic neurinomas are about 8-10% of all intracranial tumors there are only few cases about acoustic neurinomas causing hemorrhage. Pathologic changes of intratumoral vessels in tumors larger than 2 cm were considered to be a cause of the hemorrhage. This rare pathology must be remembered as one of the causes of the intracranial bleeding.

Familial glioma in two siblings.

We report two siblings who had intracranial gliomas, one with glioblastoma multiforme and the other with mixed oligo-astrocytoma. The genetic influences in the development of glioma are discussed.
