Microscopy Challenge: Cells Found in Cerebrospinal Fluid
Clinical case: CSF analysis in a 56-year-old woman with prolonged fever and positive meningeal symptoms. How to characterize the cells in the counting chamber?
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
