Clinical presentation of idiopathic CD4 lymphocytopenia.

An otherwise healthy man (60s) presented to our emergency department 5 years ago with stroke-like symptoms. Underlying cryptococcal meningitis infection was ultimately discovered leading to extensive workup to rule out underlying malignancy and HIV infection. Results returned negative with the exception of a CD4 count less than 25 /mm Several years later, he again presented to the emergency department with fatigue.
