Chondromyxoid fibroma of the frontal bone in a teenager.

We report a skull chondromyxoid fibroma with symptomatic intracranial extension causing initial misdiagnosis as a psychiatric disorder in a 14-year-old child. CT performed for work-up of the patient's "stuffy nose" revealed a large calcified frontal bone mass with extensive intracranial growth. We present this child with the diagnosis of intracranial chondromyxoid fibroma with detailed neuroimaging and neuropathology correlations.
