A 65-year-old man presented with bitemporal hemianopsia. He had undergone frontal craniotomy for a Rathke's cleft cyst associated with narrowed visual field 8 years earlier. His vision had returned to normal soon after surgery and he remained asymptomatic until the present complaint. Neurodiagnostic imaging revealed a recurrence of the intrasellar cyst extending into the suprasellar cistern. His vision improved rapidly after a second surgery. The histological findings were the same as those of the previous operation; the cyst wall was composed of a single layer of ciliated columnar epithelium resting on a collagenous connective tissue stroma.

Background: Epidermoid cyst (EC) located completely within the pituitary infundibulum is a rare entity with only seven reported cases. In this study, we have described our experience with resection of intra-infundibular epidermoid cysts (IECs) and reviewed the existing literature highlighting its distinguishing features and operative nuances.
Methods: Three consecutive cases of IEC operated at our institute was retrospectively studied.

Background: The co-occurrence of Rathke cleft cysts (RCCs) and meningiomas in the sellar and parasellar regions represents an exceedingly rare clinical entity. Achieving maximal resection through a single operative approach while minimizing adverse events is challenging, often necessitating multiple surgical approaches, as suggested by previous reports.
Observations: The authors report the case of a 49-year-old female with a history of kidney transplant who presented with headaches and was diagnosed with coexisting RCC and meningioma in the sellar and planum sphenoidale regions, respectively.

Background: Rathke cleft cysts (RCCs) are benign sellar/suprasellar lesions that result from mucin-secreting vestigial remnants within the pars intermedia of the pituitary gland. When symptomatic, they can present with retro-orbital headaches, visual field defects, and/or pituitary dysfunction.
Observations: A 35-year-old female presented with subacute retro-orbital headache, right ptosis, and blurred vision.

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.
