Keeping in mind that lesions located in the splenium of the corpus callosum can sometimes be temporary may help us avoid invasive diagnostic and therapeutic methods. Transient lesion in the splenium of the corpus related to using or withdrawal of antiepileptic drugs are rarely encountered. In this article, we present a non-epileptic patient found to have a centrally located isolated lesion in the splenium of the corpus callosum on the tenth day following the sudden withdrawal of carbamazepine after two weeks of use. The lesion was observed to disappear two months later and the carbamazepine treatment or sudden withdrawal of the drug was thought to be responsible for this reversible splenial lesion.

A 60-year-old female was admitted to our clinic complaining of a long-lasting headache. Cranial magnetic resonance imagining examination of the patient revealed a 22x24 mm extra-axial, well-demarcated, mass lesion based on the left tentorium. The patient underwent a craniotomy and the tumor was totally excised with the adjacent tentorium. ⋯ The rest of the clinical course was uneventful and the patient was released from the hospital without any neurological deficit. Intracranial schwannomas can rarely originate from atypical dural locations and radiological techniques are not always helpful in distinguishing tentorial schwannoma from tentorial meningioma. We presented a patient with a tentorium schwannoma mimicking meningioma and discussed the current literature.

Case Reports
Iliocaval arteriovenous fistula following lumbar disc surgery: endovascular treatment with a Stent-graft.
Arteriovenous (AV) fistulae, pseudoaneurysms, and lacerations may occur during disc surgery. AV fistula after lumbar disc surgery is rare. ⋯ Treatment was transcatheter covered stent placement at the fistulous site of right common iliac artery using a self expandable stent-graft. We suggest use of minimally invasive interventional techniques in the management of suitable vascular injuries following lumbar disc surgery.

Neurocysticercosis, involvement of the central nervous system by taenia solium, is one of the most common parasitic diseases worldwide. However, isolated spinal involvement by neurocysticercosis, either intramedullary or extramedullary, is uncommon. ⋯ Diagnosis was confirmed after surgical excision and the patient is doing well at six months follow up with no neurological deficits. Spinal neurocysticercosis should be considered in the differential diagnosis in high-risk populations with new symptoms suggestive of a spinal mass lesion.

Stab injuries of the spinal cord are rare. We report a case of a 22-year-old male who was hospitalized because of a spinal cord injury resulting from a stab wound in the posterior thoracolumbar area. On admission, the patient had 2/5 muscle strength of the right leg (monoparesis) and hypoesthesia below the L1 level. ⋯ An urgent right T12 hemilaminotomy was performed and retained knife fragment was removed. Six months after operation, the motor deficit had completely improved although hypoesthesia was still present. Surgery should be considered as the first-line treatment in cases of incomplete injuries of the spinal cord with retained metallic object.
