| Abstract | Invasive prolactinomas often require multimodal management including medical and surgical interventions. Here, we present the case of a 34-year-old man with a history of progressive visual disturbances. MRI unveiled a sella lesion with suprasellar and retrosellar extensions. Elevated prolactin levels (6125 ng/mL) confirmed the diagnosis of prolactinoma, leading to initiation of medical treatment, with gradual escalation to maximum dosing. The patient achieved only partial hormonal response and incomplete improvement of symptoms, and therefore, surgical intervention was pursued with objective of maximum safe resection. The patient consented to the procedure. An endonasal endoscopic approach was selected. Surgical procedures encompassed transsellar, transtuberculum, and transplanum approaches, extended laterally to expose the right parasellar carotid and the anterior wall of the cavernous sinus. Subsequent steps involved opening the sellar and suprasellar dura mater, anterior wall of the cavernous sinus, and transcavernous hemipituitary transposition for access to the retrosellar region.1-5 Debulking of the lesion was performed, followed by dissection of the retrosellar space and resection of tumor component within the interpeduncular cistern. Reconstruction employed dura substitute and vascularized nasoseptal flap. Histopathology confirmed diagnosis of prolactinoma. Postoperative MRI findings and significantly improved prolactin levels (50 ng/mL) were compatible with near total resection. The patient's postoperative course was uneventful, resulting in discharge on the second postoperative day. The patient was additionally started on cabergoline 0.5 mg 2x/week to achieve hormonal control. This case demonstrates the application of surgical anatomy and its translation in modern surgical techniques that allow improved resection of such complex tumors while ensuring optimal clinical outcomes. |
