Abstract:
Intravascular large B-cell lymphoma (IVLBCL) is a rare non-Hodgkin lymphoma with variable clinical manifestations. Although neurological symptoms are common in patients with IVLBCL, isolated cauda equina-conus medullaris syndrome is rarely reported. We herein report a case of IVLBCL whose initial presentation was cauda equina-conus medullaris syndrome with neither dermatological nor hematological manifestations. A 54-year-old man without known immune-compromised state presented with progressive ascending numbness and weakness of bilateral legs and urine incontinence for 2 months. Lumbar-sacral magnetic resonance images showed gadolinium-enhanced conus medullaris and cauda equina nerve roots. Cerebrospinal fluid analysis revealed lymphocyte predominant pleocytosis and elevated protein level without malignant cells. Focal seizure and mental status changes followed several weeks later. Brain biopsy led to the diagnosis of IVLBCL. Conclusions: IVLBCL should be included in the differential diagnosis of patients with isolated cauda equina-conus medullaris syndrome. A survey of previously published cases in the literature also showed that early initiation of chemotherapy has better outcome.
