Erythrocytes are crenated
, some with cytoplasmic spikes (echinocytes).
Degenerate sporoblasts and spores appear crenated
(Figure 2, panel B).
Another form of atypia seen in RO, which can be confused with ChRCC, is crenated
, small, dark nuclei that also represent degenerative changes, mimicking the wrinkled, clefted nuclei in ChRCC (Figure 4, A).
It is often difficult if not impossible to distinguish between SAH and TLP (1, 2) by available CSF tests such as (a) measurement of xanthochromia of the supernatant after centrifugation, (b) counting of erythrocytes in the first and last tubes of collected CSF, or (c) searching of CSF microscopically for crenated
Occasional neurons or groups of neurons were crenated
and darkly stained.
