We report a case of Rathke's cleft cyst associated with cholesterin granuloma in an 8-year-old girl with apoplexy. She was admitted to our hospital in April 1996 because of repeated headache and deep ophthalmic pain, without any visual disturbance. Computed tomography (CT) of the pituitary demonstrated an intrasellar isodense mass extending to the suprasellar cistern. Magnetic resonance imaging (MRI) showed a high-intensity mass on both T1- and T2-weighted images. The preoperative diagnosis of this lesion was Rathke's cleft cyst associated with a craniopharyngioma and/or hemorrhage. Transsphenoidal microsurgery was performed, and a bloody coffee-like serous and mucinous-yellowish substance was evacuated. Curettage of the wall removed the yellowish hard mass and soft membranous tissue. Histological examination of this tumor revealed a Rathke's cleft cyst with cholesterin granuloma.

This paper investigates the potential of artificial intelligence (AI) and machine learning (ML) to enhance the differentiation of cystic lesions in the sellar region, such as pituitary adenomas, Rathke cleft cysts (RCCs) and craniopharyngiomas (CP), through the use of advanced neuroimaging techniques, particularly magnetic resonance imaging (MRI). The goal is to explore how AI-driven models, including convolutional neural networks (CNNs), deep learning, and ensemble methods, can overcome the limitations of traditional diagnostic approaches, providing more accurate and early differentiation of these lesions. The review incorporates findings from critical studies, such as using the Open Access Series of Imaging Studies (OASIS) dataset (Kaggle, San Francisco, USA) for MRI-based brain research, highlighting the significance of statistical rigor and automated segmentation in developing reliable AI models.

Background: Craniopharyngiomas are epithelial tumors derived from the remnants of the Rathke pouch, while Rathke cleft cysts (RCC) are benign cystic lesions originating from the Rathke pouch itself [1]. Rathke cleft cysts comprise 10-15% of the hypophyseal tumors, while craniopharyngiomas are relatively rare, comprising only 2-5% of intracranial tumors [2]. Both located in the sellar and parasellar regions and share clinical symptoms including headache, visual disturbances, and endocrine dysfunction [3].

Rathke's cleft cysts (RCCs) are benign, cystic lesions that account for less than 5% of cases in the pediatric population. While asymptomatic RCCs often require only conservative management, symptomatic cases may necessitate surgical intervention. Advances in surgical techniques have improved the safety of these procedures.

Purpose: Rathke's cleft cysts (RCC) are present in up to 20% of autopsy studies but only a minority necessitate surgical treatment. Inflammation of RCC is thought to be significant in three processes: the development of classical symptoms, a predisposition to rupture or apoplexy, and increasing the rate of RCC recurrence. We aim to characterize clinical presentation, histological and radiological findings in patients with surgically managed RCC.
