Lumbosacral Plexopathy: Initial and Infrequent Manifestation of RelapsedNon- Hodgkin's Lymphoma

Lymphoma is a blood tumor, with an incidence of 11 cases per 100,000 inhabitants being 25% Hodgkin lymphoma (HL) and 75% non-Hodgkin's lymphoma (NHL). Peripheral neurological involvement is very uncommon (1-5% of lymphomas) and the most are due to NHL. The mechanisms described in peripheral neurological involvement are extrinsic tumor compression, direct infiltration, chemoradiotherapy, infection or paraneoplastic autoimmunity. We report the case of a patient of 69 years with a history of NHL in complete remission with progressive symptoms of pain, weakness, paresthesia and hypoesthesia in right lower limb. After complementary tests, infiltrative lumbosacral plexopathy as the initial manifestation of relapse NHL was diagnosed. For this reason the patient underwent hematological and rehabilitation treatment, without clinical improvement from the functional point of view. We highlight the case because of the uncommon of their presentation and the importance of diagnosis as to the prognosis for recovery.
