Pathology slides
- Figure 1. High magnification image of H&E stained slide showing
lymphoid tissue composed of small lymphocytes with scattered
megakaryocytes (arrows) and clusters of myeloid and erythroid cells
(circled)
- Figure 2. Immunohistochemical stain “CD61”, highlighting the
cytoplasm of megakaryocyte in brown chromogen and confirming the
lineage.
- Figure 3. Immunohistochemical stain “MPO”, highlighting the myeloid
precursors.
- Figure 4. Immunohistochemical stain “Hemoglobin A”, highlighting the
erythroid precursors
- Sagittal T2 WI of the LSS shows diffuse low signal intensity of the
bone marrow of LSS ( known case of thalassemia major) with
well-defined mass of the same signal intensity (5.3 x 3 cm) in
presacral region (blue arrow) and another similar smaller mass (2x 1
cm) in anterior extradural space posterior to S1 level (Blue arrow)
- Axial post contrast fat
saturated image at presacral region shows mild enhancement of the
presacral mass (Blue arrow). No definite infiltration of the sacrum.
- Axial post contrast fat saturated image at S1 level shows mild
enhancement of anterior extradural mass (blue arrow) at the midline
laterally displacing S1 traversing nerve roots.
