CT showed a contrast enhancing mass of 20 x 20 x 13 mm invading the left sella turcica (Figure 1), confirmed by an MRI. Complete blood count and peripheral smear were normal.
The positron emission tomography-computed tomography (PET-CT) shows a widespread pathological uptake of radiotracer (F-FDG), including bones, kidneys, and an intraperitoneal pelvic mass.

A transphenoidal biopsy of the mass showed a high-grade B Lymphoma of the Burkitt type (Figures 3 and 4) with a majority of medium-size cells with moderate cellular pleomorphism and variable nucleolar prominence.
The proliferation rate (Ki67/MIB1) is 100% (a). The tumor cells expressed B lymphoid markers (not shown) with a coexpression of CD10 (b).
