[Show abstract][Hide abstract] ABSTRACT: Cerebro-spinal fluid (CSF) leakage caused by defects on the dura mater after trauma or some neurosurgical interventions is an important issue. In this study, we investigated the effects of local and systemic use of phenytoin sodium on dural healing. MATERIAL and
Thirty-six male Wistar rats were divided into control, local phenytoin and systemic phenytoin groups with 12 rats in each. For each group, a dura defect was created at thoracic segment. Subjects were sacrificed at following 1st and 6th weeks and damaged segments were isolated. The results were compared histopathologically by Hematoxylin-Eosin and Masson-Trichrome staining. Criteria for the rate of collagen, neovascularization, and granulation formation were assessed semi quantitatively according to the histological assessment scale modified by Ozisik et al.
Better healing was achieved in the systemic and local phenytoin groups than in the control group. The level of healing was significantly higher in the systemic group in both early and late periods than in other groups (p < 0.01). The level of healing in the late-local group was also statistically significantly higher than that in the control group.
We observed that both systemic and local uses of phenytoin sodium (especially systemic) have positive effects on dura healing.

[Show abstract][Hide abstract] ABSTRACT: Aplasia cutis congenita (ACC), is a rare anomaly presenting with a solitary scalp lesion of skin abrasion. Lesions can be multiple and on different surfaces of the body but are mostly seen on the scalp (%70) as a solitary lesion. As it is a rare disease, we aimed to describe our case with ACC.
Our case was a newborn infant with a large full thickness skin and skull defect on the scalp at birth. He also had hypoplasia on the fingers, omphalocele, ectopic anus, cleft lip and palate anomalies and multiple cardiac anomalies. We planned further evaluation but he died 23 hours after birth because of cardiac problems.
Multiple factors have been described as etiological factors for ACC but the etiology is not clear yet. ACC may also be associated with some syndromes. Management strategies are based on the size, presence of an underlying skull defect and the child's physical condition.

[Show abstract][Hide abstract] ABSTRACT: Spinal canal extradural arachnoid cyst is an uncommon, expanding lesion which may communicate with the subarachnoid space. They may be either intra or extradural with intradural cysts being less common. Spinal arachnoid cysts are usually in the thoracic spine, and they may cause symptoms due to spinal cord compression. Although surgery is the preferred way of management, there are reported cases with long term follow-up in the literature. Here we present a 14-year-old female who presented with intermittent low back pain for 1 year and a spinal arachnoid cyst that was followed for two years without any neurological deterioration.

[Show abstract][Hide abstract] ABSTRACT: Teratoma is the most frequently encountered intracranial tumor at birth and constitutes 18-20% of all germ cell tumors. They are usually located in pineal and suprasellar regions. The authors aim to report an extremely unusual presentation, location, and appearance of a teratoma in a newborn.
A soft tissue swelling in the vertex was detected in a 1-month-old girl. Neurological examination was normal. A big, cystic-solid lesion beginning from pineal region and extending to the scalp was detected in magnetic resonance imaging. It is interesting to note that cerebral venous angiography showed that the superior sagittal sinus (SSS) was divided into three branches at the level of the lesion and they joined together distally. The tumor was excised totally. Histopathological examination revealed the diagnosis of a mature cystic teratoma.
A mature cystic teratoma mimicking parietal encephalocele is extremely rare. Germ cell tumors should be kept in mind in the differential diagnosis of all midline lesions with unusual radiographic appearance. Cerebral venous angiography or MR angiography must be performed for the diagnosis and the surgical planning in lesions located near SSS.
