Bilateral Thoracic Ganglion Cyst : A Rare Case Report
A 53-year-old female suffered from severe bilateral groin pain and dysesthesia for three months. She had this intermittent pain for 12 years, but the symptoms became worsening in the last three months. The visual analog scale score for pain was 8 out of 10. The pain was not relieved by conservative treatment. Her medical history was unremarkable. Her neurological examination was normal but she was suffering so much groin pain while walking. Thoracic magnetic resonance imaging (MRI) revealed bilateral, well circumscribed extradural, intraforaminal masses in continuity with the right and left apophyseal joints at Th12-L1 level (). Sagittal T2-weighted thoracolomber MRI revealed the bilateral roots compression caused by this cystic lesion cystic lesions at Th12-L1 level (). The patient underwent bilateral hemi-laminectomy and flavectomy at the Th12 level. Using the operative microscope, following exposure the foramens, bilateral cystic masses, emerging from the facet joints and compressing the dural sac and nerve roots were removed. The cysts were adhered tightly to the first lumbar dorsal root ganglion. The histopathological findings were consistent with ganglion cyst (). The patient made an excellent post-operative recovery with full resolution of preoperative symptoms.
