Posterior fossa midline cryptococcoma in a patient with idiopathic CD4 lymphocytopenia.

Idiopathic CD4 lymphocytopenia (ICL) is a rare disorder which is often diagnosed as HIV-negative AIDS in the light of poor immunity and AIDS-defining illnesses. We present a case of a 50-year-old male who presented with a midline posterior fossa tumour with ICL diagnosed as cerebellar cryptococcoma.
