Citar como: Vizcarra M, Mujica M, Sánchez V, Méndez P. Adolescente con inestabilidad lumbosacra por presencia de quiste hidatídico: reporte de caso. Rev Peru Med Exp Salud Publica. 2017;34 (1) RESUMENLa hidatidosis, causada por el Echinococcus granulosus, afecta a la columna vertebral en 0,5-2% del total de casos, siendo la columna sacra una ubicación rara, típica de personas en edad adulta. Se reporta el caso de un varón de 14 años oriundo de Juliaca (Puno, Perú) quien presentó lumbalgia crónica y síndrome de cauda equina. Atendido inicialmente en Juliaca, fue trasladado al Hospital Edgardo Rebagliati Martins (Lima, Perú) con el diagnóstico de tumoración sacra. En la resonancia magnética se mostró una tumoración multiquística con lisis del L5 y S1 e inestabilidad. El tratamiento quirúrgico fue una laminectomía L5-S2 y extracción de múltiples quistes de hidátide más estabilización lumbopélvica con tornillos transpediculares. En el posoperatorio se recetó albendazol (15 mg/kg/d) por el periodo de seis meses. Se debe considerar al quiste hidatídico dentro del diagnóstico diferencial cuando existan lesiones quísticas en la columna vertebral, sobre todo en regiones endémicas como el Perú.

AN ADOLESCENT WITH LUMBOSACRAL INSTABILITY DUE TO THE PRESENCE OF A HYDATID CYST: A CASE REPORT ABSTRACTHydatidosis, caused by Echinococcus granulosus, affects the spinal column in 0.5-2% of all cases, with the sacral column being a rare location typically observed only in adults. The case is reported of a 14-year-old boy from Juliaca (Puno, Peru) who presented with chronic lower back pain and cauda equina syndrome. He was initially attended to in Juliaca, and then transferred to the Hospital Edgardo Rebagliati Martins (Lima, Peru) with a diagnosis of sacral tumor. In magnetic resonance imaging, a multicystic tumor was seen with L5 and S1 lysis and instability. The surgical treatment was an L5-S2 laminectomy and extraction of multiple hydatid cysts followed by lumbopelvic stabilization with transpedicular screws. Post-operatively, he was prescribed albendazol (15 mg/kg/d) for six months. Hydatid cysts should be considered within the differential diagnosis when there are cystic lesions in the spinal column, particularly in endemic areas such as Peru.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
