We report here a rare case of adult-onset multiloculated hydrocephalus (MLH) after Cryptococcal meningitis. A 63-year-old man had Cryptococcal ventriculitis in 2011, and he recovered with treatment of antimycotic drugs. However, he was admitted again because of disorientation and amnesia, and brain MRI showed dilation of the inferior horn of the left lateral ventricle. He underwent a ventriculoperitoneal shunt (VPS) for noncommunicating hydrocephalus in 2019, and the disorientation and amnesia improved. One year after the VPS, he was admitted because of urinary dysfunction and gait disturbance. Brain MRI showed dilation of the bilateral anterior horns of the lateral ventricles. He underwent an additional VPS into the space in 2020, and urinary dysfunction and gait disturbance improved. This case was supposed that the symptom in agreement with the dilated ventricle by MLH was shown.
