Background:
Primary suprasellar central nervous system lymphoma (PCNSL) of the hypothalamus is a rare entity.
Material And Methods:
We report a case of a 49-year-old, healthy male presented with features of diabetes insipidus. Imaging features showed a mass in the suprasellar region involving the hypothalamus mainly tuber cinereum and infundibulum.
Results:
Preoperative fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) showed increased uptake in the mass. Biopsy revealed a diffuse type-B PCNSL. The present case emphasizes the importance of considering the diagnosis of hypothalamic lymphoma and the utility of FDG PET-CT in such situations.
Conclusion:
To our knowledge, only eight cases of suprasellar hypothalamic PCNSL have been reported in the literature.
