title: Small B-cell lymphoma presenting as diffuse dural thickening with cranial neuropathies.
abstract: The authors present a rare case of diffuse hypertrophy of the pachymeninges due to lymphomatous dural infiltration. This lymphoma arose late after orthotopic liver transplant, was Epstein-Barr virus (EBV)-negative, and arose in a setting of prior hepatitis C infection, a condition that may contribute to development of some non-Hodgkin's lymphomas. Biopsy of the dura demonstrated a small B-cell lymphoma, immunophenotypically most similar to those of mucosa-associated lymphoid tissues (MALT). Rapid expansion of the dura in this case resulted in profound hyperesthesia of the scalp, progressive blindness, deafness, and ataxia. As expected for MALT-lymphomas clinical symptoms responded well to cranial radiation.
