Neuroradiology
Parasellar tumour

neoplasm arising from the anatomical structures that border the sella turcica. The sella with its content, i.e. the pituitary gland, is delimited superiorly by the diaphragma sellae; laterally by the dural wall of the cavernous sinus, a multiloculated venous structure containing the internal carotid artery, the cranial nerves III, IV, VI, and the V1 and V2 branches of the trigeminal nerve; inferiorly by the basisphenoid bone and sphenoid sinus, posteriorly by the dorsum sellae. The suprasellar subarachnoid space lies above the diaphragma sellae, contains optic nerves and chiasm and the infundibular stalk, and is defined superiorly by the hypothalamus and anterior third ventricle. The Gasserian ganglion region, although it is not anatomically related to the sellar region, can be considered a parasellar structure.

Pathology affecting the parasellar region can arise from the pituitary gland, infundibular stalk, hypothalamus, meninges, vessels, cranial nerves and nasopharynx. Pathological processes are represented by primary and secondary neoplasms, inflammatory/granulomatous and vascular lesions. Masses can be subdivided according to their location into suprasellar (including the specific spectrum of infundibular stalk masses) and juxtasellar lesions.
