Non-Hodgkin's lymphoma of the brainstem with atrial septal mass.

Simultaneous occurrence of cardiac and central nervous system tumors have been rarely reported. A 23 years male presented to us with right cerebello-pontine (CP) angle symptoms and signs. Cranial imaging showed a mass lesion in the right pons infiltrating into the right and middle cerebellar peduncles. There was also a cardiac-atrial septal mass. The brainstem lesion was found to be a non-Hodgkin's lymphoma where as the cardiac lesion was not accessible. Central nervous system lymphomas are reported rarely and the prognosis is poor. The chances of the cardiac lesion in this patient also being a lymphoma are high, as it was a infiltrative cardiac mass, infiltrating the atrial septum.
