A HIGH CERVICAL INTRADURAL EXTRAMEDULLARY BRONCHOGENIC CYST - CASE-REPORT

This article describes a 16-year-old male patient, otherwise healthy, with intractable suboccipital pain due to an intradural, extramedullar y bronchogenic cyst at C1 level. Computed tomographic and magnetic res onance imaging scans showed an extramedullary cystic lesion on the rig ht anterolateral side of the spinal cord at C1 level. No other vertebr al, spinal cord, or cutaneous abnormality was associated. The patient underwent posterolateral resection of the C1 bony ring on the right si de, followed by complete removal of a cyst microsurgically. Histology suggested that the mass, with its contents of slightly viscous and opa que liquid, was an atypical form of bronchogenic cyst with abundant ps eudostratified ciliated epithelial cells.
