It has rarely been described. We report a case of CSF oculorrhea following surgery for recurrent sphenoid wing meningioma. A 67-year-old patient who underwent craniotomy for a recurrent sphenoid wing meningioma complained of tearing from the ipsilateral eye. Fluid collection was observed in the right periorbital area contiguous with craniotomy wound. With wide retraction of eyelids, a 1-cm longitudinal full-thickness laceration through the conjunctiva toward the lateral orbital rim was visualized in the area of the lateral canthal tendon. Steady leakage of pink-tinged serous fluid through the forniceal laceration was observed. With a presumed diagnosis of iatrogenic CSF oculorrhea, the patient was treated conservatively with resolution by postoperative day 6.en10.1097/SCS.0000000000000535info:eu-repo/semantics/closedAccessCerebrospinal fluid leakCSF oculorrheaCSF orbitorrheaiatrogenic CSF leakArticle25246947024531250Q2WOS:000335381800080Q4
