Abstract
BACKGROUND: Colloid cysts (CC) are rarely found in the sellar-suprasellar region. Differential diagnosis of CC is more challenging in this region because many other cystic lesions may locate or invade sellar or suprasellar structures. We present a large and unusual case of sellar-suprasellar colloid cyst with extension into the suprasellar, interpedincular and prepontine cisterns. This is the first case of sellar-suprasellar colloid cyst treated with endoscopic transsphenoidal approach.
CASE DESCRIPTION: A 33-year-old woman presented with a 1-year history of recurrent headaches. Her headaches had been unresponsive to medical treatment for the last two weeks. She had normal neurological and ophthalmological examinations. Neuroradiological studies showed a large cystic sellar lesion with extension into the suprasellar, interpedincular and prepontine cisterns. The lesion did not show any enhancement, not even in the cyst wall. Her hormonal status was also normal. The cystic lesion was totally resected via a purely endoscopic endonasal approach. There were no complications, and the patient was recovered completely with improvement of her headache. Pathology was consistent with a colloid cyst. At 6- month of follow-up, magnetic resonance imaging did not show any evidence of the residual or recurrent lesion.
CONCLUSION: Although rarely found in this location, CC should be considered in the differential diagnosis in patients who present with a sellar-suprasellar cystic lesion. Additionally, sellar-suprasellar CC would be a good candidate for the endoscopic endonasal approach.
