In our study, most of the MRI grades fall into Grade II, moderate sized microcysts > 3 mm.
As compared to figure Grades 1 to 4 showing Grade I- minimal microcysts criteria, Grade II- moderate microcysts criteria > 3 mm.
Histologically, this appears as dilated or "sacculated" endometrial glands admixed with small endometrial microcysts
Collapsing glomerulopathy from any cause consists of segmental or global loss of glomerular capillaries and increased matrix with overlying cellular prominence (Figure 3), sometimes associated with marked tubular microcyst
The typical stellate reticulum and microcyst
formation often seen in follicular ameloblastoma, however, was rarely encountered.
Additional features, if present (1) Hemosiderin deposition (2) Calcification (3) Microcyst formation (4) Mitotic activity (5) Pleomorphism (6) Presence of gemistocytes (7) Vascular proliferation (8) Necrosis d.
Hemosiderin deposition, calcification, and microcyst formation are nonspecific findings that occur in both malignant and benign CNS neoplasms.
