Chronically elevated intracranial pressure (ICP) can cause bony remodeling of the cranial vault. This has been reported to occur in the sphenoid bone and the ethmoid and temporal bones, where nasal or otic cerebrospinal fluid (CSF), respectively, can leak.1 We report a case of proptosis secondary to remodeling of the orbital bones in a patient with intracranial hypertension (IH) from acute lymphoblastic leukemia.
