Tension pneumocephalus related to an epidermoid tumor of ethmoid sinus origin.
A 37-year-old man presented with a four-week history of progressive left-sided weakness, frontal headache, confusion, and drowsiness. A computed tomography evaluation of the head revealed a 7-cm pneumatocele in the right frontoparietal region with shift of the falx to the left. The patient was taken to surgery, where the pneumatocele was decompressed and an epidermoid tumor that originated in the left ethmoid sinus was removed. After the operation, the presenting symptoms resolved promptly.
