There are few published articles and case reports in the literature related to hypothalamic inflammation and regression after steroid treatment. This case reaffirms the steroid responsiveness of mass-like hypothalamitis. 

We would like to emphasize that radiologists should keep in mind inflammatory lesions in the differential diagnosis of the hypothalamic region mass-like lesions. Actually, this case was initially reported as a suprasellar germinoma.

On the other hand, there are also published cases on literature that show suprasellar germinoma also could be responsive to steroid treatment. 

Special thanks for supporting this case to neurosurgeon Dr. Alesker Hasratov, from Republican Neurosurgery Hospital (Baku, Azerbaijan).
