| Each trochlear nerve makes its exit through the caudal tectum, immediately lateral to the frenulum of the superior medullary velum. |
| Structurally, the tumor cells were arranged in a medullary pattern composed of polygonal tumor cells. |
| The glomerular tufts were shrunken or necrotic and renal medullary rays were congested. |
| These three are separated from each other by the medial and lateral medullary laminae of the globus pallidus. |
| The interfollicular area and medullary cords were heavily infiltrated by mature plasma cells with a sheetlike arrangement in some areas. |
| The tumor is eccentric, usually metaphyseal, but it may extend into the epiphysis or along the medullary cavity into the diaphysis. |
