Medulloblastoma with Excessive Nodularity: Radiographic Features and Pathologic Correlate

Figure 2

Histologic features of medulloblastoma with extensive nodularity. Hematoxilin and eosin section (4 μm; 100x) reveals a malignant small blue cell tumor with widespread formation of nodules of uniform cells with neuropil formation surrounded by intervening areas of more densely populated pleomorphic cells consistent with a diagnosis of medulloblastoma with extensive nodularity. The arrowheads point to the nodular zones.
