When polyuria does not stop: a case report on an unusual complication of hantavirus infection

摘要

Magnetic resonance imaging of the sellar region. Magnetic resonance imaging (MRI) of the head disclosed a hemorrhagic intrasellar mass (arrow) with compression of the optic chiasm on initial presentation (a, native T1-weighted sequence in sagittal orientation shows a hyperintense signal in the periphery of the mass due to blood. b, subtraction of native and contrast-enhanced T1-weighted sequences shows only minimal peripheral and central enhancement). Follow-up MRI shows a shrinking and organized sellar hematoma after 3 weeks (c, native T1-weighted sequence) and 3 months, respectively (d, native T1-weighted sequence)
