A male in his 70s with history of Parkinson's disease presented with complaints of double vision and falls on the left side.
An MRI scan revealed an approximately 2 cm extra-axial right frontal convexity mass with apparent uniform enhancement. MRI scan also showed diffuse volume loss involving the brain, particularly at the frontal parietal convexity (Fig. 1).
A craniotomy was performed and an intra-operative consult was requested.
Touch preparations were performed (Figs. 2, 3 and 4)
An intra-operative diagnosis was rendered and the surgeon completed the excision of the mass.
The excised specimen consisted of rubbery lobulated hemorrhagic tan tissue, 2.4 cm in maximum dimension.
