PET-CT imaging of combined brachial and lumbosacral neurolymphomatosis.
Neurolymphomatosis is a rare manifestation of progressive non-Hodgkin's lymphoma. A 44-yr-old man with diffuse large B-cell lymphoma presented with unilateral progressive peripheral sensorimotor neuropathy after the 7th cycle of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) therapy. No pathology in the nervous system was evident by computerized tomography (CT), magnetic resonance imaging (MRI) of the head, spinal axis and plexuses and by repeated analysis of cerebrospinal fluid. However, the hybrid modality of positron emission tomography (PET) of fluorinated deoxyglucose (FDG) combined with CT scan (PET-CT) showed unilateral involvement of both the brachial and lumbosacral nervous plexuses. A complete recovery of neurological manifestations and normalization of PET-CT followed intensive chemotherapy with autologous stem cell transplantation. The diagnosis and localization of neurolymphomatosis may be supported by PET-CT imaging.
