A 55-year-old woman presents with chronic headaches and visual disturbances. MRI shows a well-circumscribed, dural-based mass attached to the falx cerebri. Histology shows whorled arrays of meningothelial cells with numerous laminated calcifications. What are these calcified structures called?
- A Psammoma bodies ✓
- B Verocay bodies
- C Rosenthal fibers
- D Hyaline arteriolosclerosis
Correct answer: A. Psammoma bodies
Explanation
The dural-based mass is a meningioma. It characteristically shows whorled meningothelial cells and psammoma bodies, which are laminated calcifications. Verocay bodies are seen in schwannomas, Rosenthal fibers are seen in pilocytic astrocytomas, and hyaline arteriolosclerosis is a vascular change in hypertension.
