Neuro Histologic characteristics of this brain tumor?

A 40-year-old woman presents to the physician because of a recent onset of seizures. CT of the head reveals a supratentorial, contrast-enhancing mass that is smooth in contour and adjacent to dural structures without parenchymal invasion. The tumor is successfully treated by surgical excision.

Which of the following histologic characteristics most definitively confirms this patient's diagnosis?

a) Embryonal Cell
b) Laminated Calcifications
c) Neovascular Proliferations
d) Round nuclei with clear cytoplasm
e) Undifferentiated tumor growth

Correct Answer Answer is B

Yeap,

There are a few clues in this Question.

1. Supratentorial - Enhacing Mass with contrast = Psammomas bodies
2. No Tumor Invasion
3. Resectable

The 3 makes it more likely to be "Meningioma"

Which makes B, more likey to be because Psammomas are just calcified enhancing lesion in a smooth whorl pattern.
