Intrasellar cysticercosis cyst treated with a transciliary supraorbital keyhole approach - A case report.

Background: Neurocysticercosis is the most common parasitic disease affecting the central nervous system. Isolated sellar cysticercosis cysts are rare and can mimic other sellar lesion as cystic pituitary adenoma, arachnoid cyst, Rathke cleft cyst, or craniopharyngioma. The surgical resection is mandatory because the cysticidal drugs are ineffective, however, new microsurgical approaches are emerging to reduce complications and need to test in this condition. We present a patient with a sellar cysticercosis cyst treated by transciliar supraorbital keyhole approach.

Case Description: A 45-year-old female with presented with chronic severe headaches, progressive deterioration of 6 months in visual acuity and bitemporal hemianopia. The pituitary hormonal levels were normal. Magnetic resonance findings showed a sellar and suprasellar cyst and underwent a microsurgical supraorbital transciliar keyhole approach for lesion resection. Pathologically, the lesion demonstrated a parasitic wall characterized by wavy, dense cuticle, and focal globular structure, surrounding inflammatory reaction with plasma cells. Postoperatively, the patient recovery fully neurologically.

Conclusion: Intrasellar cysticercosis cyst causes significant neurological deficits due to its proximity to the chiasm, optic nerves, pituitary stalk, and the pituitary gland. Surgical section is an effective treatment. The supraorbital keyhole craniotomy offers satisfactory exposure, possibility of total resection with dissection of the supra and parasellar structures, short operative time, less blood loss, short hospital stay, and good overall surgical outcome.
