In recent years, resections of midline skull base tumors have been conducted using endoscopic endonasal skull base (EESB) approaches. Nevertheless, many surgeons reported that cerebrospinal fluid (CSF) leakage is still a major complication of these approaches. Here, we report the results of our 42 EESB surgeries and discuss the advantages and limits of this approach for resecting various types ...

Chondroma is a benign cartilaginous tumor, usually arising from the small bones of hands and feet, but also been found on several sites of the body. They are rarely diagnosed inside the cranial vault, and in that case more frequently related with the skull base. Nevertheless, there are few isolated cases reports of chondromas arising from the convexity dura, falx, choroid plexus, or intraparenc...

introduction: skull-based osteomyelitis is bony infection which generally originates from inadequately treated chronic infection, adjoining tissue infection or after trauma.case: 11 month female child had a trivial fall while standing near a bucket. the child developed fracture of right clavicle and left orbital swelling which was inadequately treated. this resulted in in spread of infection to...

localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. despite development of many techniques including angiography, mri, sonography, and frame base stereotaxy, a more accurate localizing technique is still needed (1, 2). a step forward to achieve this goal is to develop a navigation system. in this manuscript, we explained so...

OBJECTIVE Based on surgical outcomes of patients with infratentorial meningiomas surgically treated at our institution, we analyzed the predictors for surgical resection, recurrence, complication, and survival. METHODS Of surgically treated 782 patients with intracranial meningioma, 158 (20.2%) consecutive cases of infratentorial location operated on between April 1993 and May 2013 at out ins...

AIM Olfactory groove meningiomas make up 4 to 13% of meningiomas. The first line treatment of meningiomas is surgery, but the extent and types of approaches advised for olfactory groove meningiomas are diverse, from aggressive skull base approaches to standard or minimally invasive craniotomies and endoscopic approaches. We retrospectively reviewed our series of olfactory groove meningiomas tha...

Background: Meningiomas are slow-growing neoplasms, accounting for 20% of all primary intracranial neoplasms and 25% intraspinal tumors. Atypical anaplastic meningiomas infrequent, representing fewer than 5% meningiomas. Unusually, they can show aggressive behavior, extracranial metastases extremely rare, approximately 0.1% reported cases. Case Description: Fifty-six-year-old male patient diagn...

BACKGROUND To evaluate the impact of 68Ga-DOTATOC-PET on treatment planning and sparing of normal tissue in the treatment of skull base meningioma with advanced photons and protons. METHODS From the institutional database consisting of 507 skull base meningiomas 10 patients were chosen randomly for the present analysis. Target volume definition was performed based on CT and MRI only, as well ...
