Inflammatory pseudotumor (IPT) is a benign entity that may present as a solid mass mimicking a malignant neoplasm. Histologically, they are composed of varying proportions of myofibroblastic spindle cells, lymphocytes, and plasma cells. Skull base IPT is rare and usually occurs in adults with no sex predilection. The skull base IPT typically presents with headache, and/or cranial nerve palsy. T...

chondromas are benign tumors that may be found in many parts of the body. among intracranial neoplasms, tumors of cartilaginous origin are rare. it has been shown that most of these tumors arise from the skull base. their occurrence in other parts of the intracranial cavity is unusual. chondroma of falx is a rare neoplasm. in this report we introduce a case of falcine chondroma arose from front...

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...
