[The unmasking of secondary adrenal insufficiency and central diabetes insipidus by a highly febrile acute Hantaan virus infection].

CASE REPORT: A 32-year-old obese patient was admitted to our hospital as an emergency with very severe abdominal pain. Routine examinations initially failed to establish a diagnosis. The patient then went on to develop a high fever that was associated with polydipsia and polyuria. Serological studies revealed an acute infection with the Hantaan virus. Laboratory investigations showed hypofunction of the anterior and posterior lobes of the pituitary, with complete absence of ACTH, which was caused by two germinomas located intracranially.

CONCLUSION

The clinical symptoms had thus been the result of acute secondary insufficiency of the adrenal cortex, which was unmasked by the acute, highly febrile Hantaan viral infection.
