Multiple myeloma masquerading as sellar mass: A case report and review of literature

摘要

Tumors involving sellar and parasellar regions can present with headache, visual disturbances, cranial nerve deficits, and other neurological symptoms. Patients with such tumors can also presentwith endocrine dysfunction due to a hormone excess or deficient state. As many lesions in this critical area are slow growing in nature, they may evade early clinical detection and may present after a long period of time. Pituitary adenomas represent an overwhelming majority of sellar masses, whereas various nonpituitary tumors or metastases can also present with similar findings. Differentiation between pituitary and nonpituitary pathology is critical, as management strategies for the disorders mentioned earlier differ significantly. In such cases, radiological and histopathological evaluations are pivotal for arriving at a correct diagnosis. We describe an interesting case of sellar mass that presented with cranial nerve deficits and endocrine dysfunction, which was subsequently attributed to the myelomatous involvement of sella due to a relapse of multiple myeloma.
