Abstract
Chondromas are a benign cartilaginous tumor that account for approximately 0.5% of primary intracranial tumors. They usually arise from the synchondrosis of the skull base, being rarely reported elsewhere (dura convexity, falx, or even intraparenchymal). Because they are very rare tumors sharing clinical behavior and imagiological similarities with the much more common meningioma, the clinical diagnosis is frequently mistaken after an initial imaging workup. The authors present a case of a 48-year-old woman, with frequent headaches and an extra-axial tumor arising from the anterior falx, initially diagnosed as a meningioma.
Resumo
Condromas são tumores cartilaginosos benignos que correspondem por aproximadamente 0,5% dos tumores primários intracranianos. Eles geralmente surgem da sincondrose da base do crânio, sendo raramente registrados em outros locais como a convexidade dural, a foice, até mesmo no parênquima cerebral. Por serem tumores muito raros que compartilham comportamento clínico e imagiológico com meningiomas, o diagnóstico é frequentemente confundido após exame de imagem inicial. Os autores apresentam o caso de uma mulher de 48 anos, com cefaleia frequente e um tumor extra-axial ascendendo da foice anterior, inicialmente diagnosticado como um meningioma.
