A 46-year-old male presented with acute visual loss in the right eye, high fever, nausea, and vomiting. This was caused by herniation of the third ventricle into empty sella at 15 months of surgery for pituitary apoplexy. The sellar-suprasellar tumor was totally removed via a transcranial approach. Histological examination showed chromophobe adenoma with necrotic tissue, indicating pituitary apoplexy. His visual field defect worsened 15 months after the operation, and magnetic resonance imaging revealed moderate hydrocephalus and protrusion of the dilated anterior inferior portion of the third ventricle into the sella. The optic nerve, optic chiasm, and pituitary gland were compressed onto the sellar floor. Ventriculoperitoneal shunt relieved the visual impairment. A decompressive procedure such as ventriculoperitoneal shunts is a reasonable treatment for such a marked herniation of the third ventricle.
The case of a 55-year-old immunocompetent woman with central nervous system cryptococcosis and multiple intraventricular cysts is presented. The cysts did not enhance on MR and had signal characteristics similar to cerebrospinal fluid on T1- and T2-weighted images; their intensity was lower than cerebrospinal fluid on proton density-weighted images.
