Results of repeated cerebrospinal fluid studies were normal and not indicative of meningeal infiltration of NHL or encephalitis.

Central nervous system invasion by the NHL was ruled out by cerebral imaging, but unenhanced cranial computed tomography (CT) showed a large space-occupying lesion in front of the upper brainstem (Figure 1). Magnetic resonance imaging did not show any signs of structural damage caused by mass effect on brainstem . . . [Full Text of this Article]
