Dentro de las causas m芍s frecuentes se encuentran las roturas de aneurisma de aorta abdominal, tumores renales y suprarrenales, entre otras. Habitualmente es dif赤cil realizar el diagn車stico al ingreso del paciente, ya que la presentaci車n cl赤nica es variable y puede simular otros cuadros de dolor abdominal o lumbar. Las t谷cnicas de imagen, especialmente la angiograf赤a, tomograf赤a computada y resonancia magn谷tica, son una herramienta fundamental en el diagn車stico y manejo oportuno del cuadro. Presentamos el caso de un var車n de 56 a os de edad con diagn車stico de VIH en tratamiento, que debut車 como un cuadro de dolor y masa abdominal palpable. Luego de un acabado estudio de im芍genes, se diagnostic車 un HRE cuyo estudio histol車gico revel車 un Linfoma de Burkitt. The spontaneous retroperitoneal hematoma (SRH) is defined as a spontaneous hematic collection located in any of the retroperitoneal compartments. The most frequently encountered cause of retroperitoneal hemorrhage is a ruptured abdominal aortic aneurysm, followed by renal and adrenal tumors, along with some other less common causes. Performing accurate diagnosis of patients at admission has proven to be difficult, given that the clinical presentation is ample and variable and may mimic other pictures of abdominal or lower back pain. Imaging techniques, mainly angiography, computed tomography, and MR Imaging, represent a fundamental tool for both timely diagnosis and proper management of the condition. We report the case of a 56-year-old male patient with diagnosis of HIV, who presented with a history of abdominal pain and palpable abdominal mass. After a thorough imaging evaluation, patient was diagnosed with retroperitoneal hematoma, whose histological analysis revealed a Burkitt lymphoma. %K Espont芍neo %K %K Hematoma retroperitoneal %K Linfoma de Burkitt %K Burkitt lymphoma %K Retroperitoneal hematoma %K Spontaneous %U http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-93082012000300004
