Aneurysmal bone cyst (ABC) arising in the petrous portion of the temporal bone is a rare entity with only five such reported cases in the literature. We report the case of a 28-year-old man who presented with a tender swelling in the right preauricular region with right ear discharge and conductive hearing loss of 4 years' duration. Computed tomography and Magnetic Resonance imaging showed a destructive lesion in the right petrous bone with cavitation consistent with the diagnosis of ABC. Gross total resection of the lesion was achieved and diagnosis was confirmed histologically. The patient had no recurrence at 12 months of follow-up. This report presents the unusual location of an uncommon bony tumor with a review of its clinical, radiological, and histopathological features as well as the treatment modalities available.

Congenital orbital teratoma is a rare condition which presents as marked proptosis of eyeball in a newborn. It is rapidly progressive with secondary damage to eyeball due to pressure effect. This case presented by us is of interest due to radiological features and rarity of this tumor extending into posterior fossa.

Primary pleomorphic xanthoastrocytoma (PXA) of the spinal cord is a rare slow growing tumor. To our knowledge, only five such cases have been reported in the literature till date. We report the clinical, radiological, and histopathological features of a spinal PXA in a 23-year-old female previously operated 5 years back for a spinal tumor, presented with weakness in lower limbs, sphincter incontinence and low back pain. Magnetic resonance imaging scan with contrast reveals an intramedullary lesion in the spinal cord from D8-D10 level. The patient was operated with reexploration of the previous incision, and gross total excision was achieved. Histopathology confirmed the diagnosis of PXA. Clinical and radiological follow-up is required to detect early recurrence. Adjunct radiotherapy or and chemotherapy should be considered only when there is postoperative residual or recurrence, however there are no definite guidelines in view of the rarity of this condition.

Supratentorial atypical teratoid rhabdoid tumors (AT/RTs) of infancy and childhood are rare, highly malignant neoplasms, most common in the first 2 years of life. In spite of multiple treatment regimens consisting of surgical resection, radiation therapy, and multi-agent chemotherapy, the prognosis is very poor. The majority of these tumors are located in the cerebellum, cerebellopontine angle, pineal gland, spinal cord, and the suprasellar region; supratentorial location is relatively uncommon, and the intraventricular location is extremely rare. We report a rare case of AT/RT arising in the lateral ventricle in a 4-year-old patient.

Aim?The aim of this study is to present our experience in management of complex, communited fractures of the frontal skull base. Patients and Methods?This was a retrospective study performed between January 2000 to January 2013. Data of 1,935 patients with head trauma operated in our department during this period were analyzed. Overall, 210 patients with compound anterior skull base fractures were reviewed. Patients were classified based on radiological features in three groups. Standard neurosurgical protocol was followed for all patients after trauma; reconstruction using titanium mesh, miniplates, and silastic graft was done 6 months to 1?year later. Conclusion?Frontal depressed fractures involving the anterior cranial base are complex and require a definitive plan of approach. Reconstruction of bony and dural defects reduces cerebrospinal fluid leak, brain herniation, and infection. Cosmetic reconstruction of the frontal deformity is necessary at a later stage.

Human hydatid disease is caused by Echinococcus granulosus. Central nervous system (CNS) echinococcosis is rare with less than 4% of cases of hydatid disease have CNS involvement. intracranial extradural hydatid cysts are rare and less than 11 case have been reported in literature. primary intracranial extradural multiple hydatid cysts are not reported as per our knowledge so we report probably the first case.
