Transsphenoidal endoscopic surgery has become a surgical procedure of choice for the treatment of pituitary tumors. The objective of the present study was to describe the demographic, clinical characteristics, complications, and postoperative results of the patients who underwent transsphenoidal endoscopic resection. We present our results of this technique in patients operated from January 2016 to August 2018 at Neurosurgery Department of the Cayetano Heredia National Hospital.

Intracranial epidermoid tumors are rare, slow-growing, and histologically benign congenital neoplasms. The microsurgical approach with endoscopic assistance is described as a minimally invasive technique that facilitates the work of the neurosurgeon in the complete resection of an epidermoid tumor located in the cerebellopontine angle. We present a case where we use a combined microscopic and endoscopy technique.

Cavernomas on the posterolateral pontomesencephalic surface can be approached from an extreme lateral supracerebellar infratentorial corridor, although the theory is scarce. The brainstem has a dense concentration of nuclei and fibers that are responsible for a high rate of morbidity when treating brainstem lesions. The objective of this work is to demonstrate the safe microsurgical resection technique for the complete removal of a pontine cavernoma.

Moyamoya disease is a chronic occlusive cerebrovascular disease of unknown etiology, characterized by bilateral stenotic and occlusive changes in the terminal portion of the internal carotid, as well as the presence of an abnormal vascular network at the base of the brain. We present a case of a 50-year-old female patient from China, with the Glasgow Coma Scale (GCS) of 9, and a clinical picture of stroke. Cerebral angiography revealed Moyamoya disease.

Pneumocephalus is a frequent complication following neurosurgical procedures. The diagnosis is based on tomographic findings and the clinical evolution of the patient. We present the clinical case of an 85-year-old man who underwent a keyhole craniotomy and subdural drainage placement due to the diagnosis of a chronic subdural hematoma (CSDH) and subsequently tension pneumocephalus.

Capillary hemangioma is an extremely rare endothelial cell neoplasm as an extramedullary intradural tumor. Its presentation in infants is anecdotal and only 2 cases have been previously reported in the literature. We present a case of a 03-month-old infant with severe abrupt-onset paraparesis. Spinal MRI showed an intraspinal tumor at the T7, T8, and T9 levels, which captures contrast. The pathology was reported as capillary hemangioma.

Rheumatoid arthritis (RA) is a systemic disease characterized by synovitis, which causes damage to the ligaments and joints. The cervical region is the region of the spine most affected, with neck pain the most frequent symptom. The three forms of presentation are atlantoaxial subluxation, cranial settlement, and subaxial subluxation. The clinical evolution of patients treated conservatively is poor, with surgery being a key element to prevent the progression of neurological deterioration.

Recurrent lumbar disc prolapses (RLDP) is not uncommon after surgery. The incidence of RLDP varies from 5-18% across the different populations in the world. The exact cause of recurrence is not known but the weakness of the annular tissue due to previous surgery, exposure to repetitive lifting, heavy work causing axial load, advanced age, smoking, are some of them. The study aims to evaluate the causative factors of RLPD and the outcome of surgeries in Bangladeshi peoples.

Hydrocephalus is one of the most common pathologies in the daily care of a Pediatric Neurosurgery Service, so it is important to document the context of its presentation to improve therapeutic behavior. The objective of the present study was to describe the demographic variables, as well as the type, treatment, morbidity, and mortality of patients with hydrocephalus.
