Purely Suprasellar (Hypothalamic) Atypical Teratoid Rhabdoid Tumor Presenting with Diabetes Insipidus and Panhypopituitarism in an Adult Male: A Case Report and Review of Literature

Atypical teratoid rhabdoid tumor (ATRT) is a rare primary malignant tumor of the central nervous system. Little knowledge is available about natural history, behavior, prognosis, and best management guidelines of such tumor. Its occurrence in adults is very rare and more predominant in females. Locations in adults are mainly cerebral hemispheres, but recently, more cases are reported in sellar/suprasellar cisterns. We are reporting a case of purely suprasellar ATRT of a middle aged male who presented initially with diabetes insipidus (DI).
