RESUMEN
Mujer de 55 años con dolor lumbar y dificultad para caminar desde hace 18 meses. En los últimos cuatro meses agrega hiporexia, dolor e inmovilidad de miembros inferiores. Internada en un hospital general (2009), recibe tratamiento antituberculoso 2HRZE/4H2R2 (INH, RFP, PZN y ETH), al habérsele detectado M. tuberculosis en un frotis de sedimento urinario. Ante inefectividad del tratamiento es trasladada al Hospital General Dos de Mayo (HNDM), en 2010, donde mediante resonancia magnética, se demuestra colapso parcial del cuerpo vertebral de L3, tumor en área craneal parietal derecha (plasmocitoma óseo a cadenas ligeras lambda) y múltiples lesiones óseas circulares sistémicas (coin lesions), en tórax, arcos costales, escápula, húmero y ambos fémures. Proteinograma electroforético en suero y en orina de 24 h, con ausencia y presencia de pico monoclonal, respectivamente. Biopsia de hueso hipoplasia celular con rango de células plasmáticas neoplásicas (3%-6%). Orina hematíes, 18-20/campo; leucocitos aglutinados; cilindros hialinos y granulosos. Urea, 108 mg/dL; creatinina, 3,6 mg/dL. El paciente desarrolla infección urinaria, hipercalcemia e insuficiencia renal y fallece sin recibir tratamiento.
ABSTRACT
A 55 year old woman with back pain and difficulty walking for 11/2 year. In the last four months she added hyporexia, lumbar pain and immobility of lower limbs. Admitted to a General Hospital (2009), she received treatment for tuberculosis 2HRZE/4H2R2 (INH, RFP, PZN and ETH), having been detected M. tuberculosis in a smear of urinary sediment. Before ineffectiveness of treatment she was taken to the General Hospital Dos de Mayo (HNDM), in 2010, where magnetic resonance, showed partial collapse of L3 vertebral body, cranial tumor in right parietal area (lambda light chain bone plasmacytoma) and systemic circular bone injuries (coin lesions) on chest, ribs, scapula, humerus and both femurs. Protein electrophoresis in serum and urine of 24 hours, showed absence and presence of monoclonal spike, respectively. Bone marrow biopsy showed general cell hypoplasia and range of neoplastic plasma cells of 3%-6%. Urine red blood cell, 18-20 per field, agglutinated leukocytes, hyaline and granular casts. Urea, 108 mg/dL; creatinine, 3,6 mg/dL. The patient develops urinary tract infection, hypercalcemia and renal failure, dying without treatment.
