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...

A 56-year-old male high-school teacher developed a personality change over a 2-month period and became unable to keep his attention on his work. He was admitted to Brigham and Women 's Hospital in April 1984 after becoming severely disoriented. Physical examination on admission revealed that the patient was alert and cooperative, but inattentive and indecisive, suggesting frontal lobe dysfuncti...

Gorlin's syndrome, or basal cell nevus syndrome, is a relatively rare disease. It consists of a classic pentad of features comprised of multiple basal cell carcinomas, jaw cysts, calcification of the falx cerebri, pitting of the palmar and plantar surfaces and rib anomalies. A review of the clinical features, differential diagnosis, clinical work-up and current treatment is presented.

We describe the MR findings in a case of chondroma arising from the falx. At MR imaging, the mass appeared well defined, lobulated, hypointense to isointense on T1-weighted images, and very heterogeneous with marked hyperintense areas on T2-weighted images. After contrast administration, this tumor enhanced slightly on delayed images.

Among intracranial meningiomas, falcotentorial meningiomas, occurring at the junction of the falx cerebri and tentorial dural folds, are extremely rare. Because of their deep location, they are surrounded by critical structures, and have been regarded as one of the most challenging lesions for surgical treatment. In this study, we describe our surgical strategy for falcotentorial meningiomas an...

A study ef dural calcification is presented. The detection by roentgenography of 164 cases of dural calcification among 1,162 neurological and neurosurgical patients represented an incidenoe of 14%. Such calcification occurred with the greatest frequency in the falx cerebri, tentorium cerebelli and petroclinoid ligament, The main contributing factors and clinical significance of dural calcifica...
