Panhypopituitarism Secondary to a Central Nervous System Germinoma.

Germ cells are the reproductive cells in a foetus which later develop into sperm in the testicles or unfertilized eggs in the ovaries. They occur in the gonads (testis and ovaries) but can also occur elsewhere in the body, including intracranially. In this case, these tumours can affect the function of the pituitary gland, causing different endocrinological conditions. Understanding the aetiology, classification, and clinical behaviour of germ cell tumours is essential for timely diagnosis, appropriate treatment, and prognostication, given the spectrum of entities encompassed by this group and their variable therapeutic sensitivity and outcomes. This case report highlights the importance of considering intracranial germ cell tumours in a young adult admitted with endocrinopathy as the first presentation.
