Review Case Reports
Surgically treated epilepsy due to developmental venous anomaly of the brain. Case report and review of the literature.
A congenital malformation of the brain vessels, developmental venous anomaly (DVA) is considered a benign lesion, requiring no intervention unless symptomatic. Epilepsy is a well-known clinical manifestation of DVA. Successful surgery for DVA-associated epilepsy with has been sporadically reported in the literature; however, in all published cases, the anomaly was left intact along with the accompanying lesion. Here we present a surgical case of DVA located in the vicinity of the motor cortex causing drug-resistant simple partial epilepsy. ⋯ DVA removal can be performed in selected cases, but more studies are needed to assess the complication rate.

Review Case Reports
Delayed development of spinal subdural hematoma following cranial trauma: A case report and review of the literature.
Spinal subdural hematomas (SDHs) have been reported secondary to direct trauma or iatrogenic causes associated with coagulopathies. Spinal SDHs found after the development of acute intracranial SDHs, without any evidence of trauma to the spine, are extremely rare. In addition to this rare presentation, there is a lack of consensus regarding whether surgical decompression is the ideal treatment strategy. Depending on the extent of SDH within the spinal canal, surgical decompression may be difficult where diffuse hematoma within the intradural space requires multilevel decompression for treatment. ⋯ This report demonstrates a very rare occurrence of a traumatic intracranial SDH migrating into the thoracic and lumbar spine. This case also highlights that despite acute neurologic deficits, conservative management may be a feasible strategy that can result in recovery of neurologic function.

Extraforaminal vertebral anomalies involve entry at cervical transverse foramina other than at C6 and can appear with other anatomic variations along the V2 segment. Such unexpected vessel courses can have implications on surgical planning. We sought to evaluate the incidence of anomalous V2 segment entries, as well as their associations with vessel dominance, medialization, and C7 pedicle width. ⋯ Extraforaminal anomalies may be more frequent than previously reported and are important considerations during subaxial cervical spine surgery planning. Particular attention should be paid to the contralateral dominance pattern within this subgroup. In patients with anomalous V2 segment entries, adherence to the standard, anatomic landmarks remains desirable.

To investigate the characteristics of the prechiasmatic sulcus in children aged between 1-20 years. ⋯ The sulcal length did not vary in children, whereas the sulcal angle decreased with an irregular pattern. The sulcal angle decreased after prepubescent period, possibly due to the sphenoid sinus pneumatization and spheno-occipital synchondrosis. The sulcal length angle mostly in infants and young children may cause surgical orientation difficult during the resection of tumors using transcranial approaches.

Klippel-Trenaunay-Weber syndrome (KTWS) is characterized by the presence of a combined vascular malformation of capillaries, veins, and lymphatic vessels; congenital venous abnormalities; and limb hypertrophy. Its association with neurovascular abnormalities is infrequent, and the presence of intracranial arteriovenous malformations (AVMs) is extremely rare. ⋯ Cerebral AVMs are extremely rare in KTWS cases; however, their presence can have serious consequences if they are treated. We find it advisable to include brain imaging tests, such as nuclear magnetic resonance imaging, to diagnose and monitor KTWS. Furthermore, a Gamma Knife may be useful when multiple AVMs are present.
