Spontaneous Ethmoid Osteo-Dural Breach: Pre- and Postoperative Imaging Perspectives

Spontaneous osteo-dural defects of the anterior skull base are rare and often linked to idiopathic intracranial hypertension (IIH) [1]. They typically present as cerebrospinal fluid (CSF) rhinorrhea, most frequently at the cribriform plate. We report a case of a 55-year-old woman with chronic headaches and clear nasal discharge. CT and MRI confirmed an ethmoid bone defect consistent with an osteo-dural breach. Endoscopic repair using the bath-plug technique was successful, with postoperative imaging confirming resolution.
