The sellar and parasellar region is anatomically complex and encompasses many important vascular, endocrine, and neural structures. Pathology that arises within this region is often similarly complex, and requires a combination of endocrinologic, ophthalmologic, and neurologic examinations combined with advanced neuroimaging modalities. Magnetic resonance imaging (MRI) has become the gold standard for characterization of sellar and parasellar pathology due to the high contrast and detail it provides. Computed tomography (CT) allows for identification of bony involvement of lesions and also the general bony anatomy of the sellar region. Both modalities combined allow for complete characterization of sellar and parasellar pathology.

Introduction: Sellar and parasellar tumors are frequent lesions in neurosurgical practice, highlighting pituitary adenomas, craniopharyngiomas, and sellar tubercle meningiomas. The clinical manifestations are similar, however; There are imaging aspects that differentiate them.
Objective: Show imaging aspects of tumors in the sellar and parasellar region that guide their histopathological diagnosis.

Objective: Calcification in pituitary adenomas is a rare occurrence and its differential diagnosis typically includes other sellar masses. Common calcifications in pituitary adenomas are classified into 2 morphological forms: capsular (eggshell-like) and multiple small nodular calcifications located within the adenoma. Also, there is a pituitary stone term.

Background: Craniopharyngioma is a rare and slow-growing benign sellar or parasellar epithelial tumor. The number of patients receiving proton beam therapy (PBT) has increased. This study aimed to systematically evaluate and analyze the comprehensive evidence regarding the safety and efficacy of PBT for craniopharyngioma.

Radiomics, a quantitative approach to extracting features from medical images, represents a new frontier in skull base oncology. Novel image analysis approaches have enabled us to capture patterns from images imperceptible by the human eye. This rich source of data can be combined with a range of clinical features, holding the potential to be a noninvasive source of biomarkers.

Schwannomas are well-encapsulated, solitary tumors that grow slowly from the nerve sheath. Sellar schwannomas tend to be mistaken for other sellar/parasellar lesions due to similar clinical and radiological findings. The present article describes the clinical presentation, radiological findings, histopathological features, and outcome of a patient with sellar schwannoma.
