| description |
A case report of a 3-year-old boy with past medical history of intestinal partially treated amebiasis, is presented. The patient was admitted to Pediatric Unit, San Cristóbal Central Hospi- tal, Táchira, Venezuela, with abdominal pain and fever. An abdominal bloating and a 3 cm palpable hepatomegaly below the right costal margin were assessed. Abdominal ultrasound revealed a liver enlarged in the right antero-superior area. A rounded space-occupying lesion, predominantly solid, with mixed-echo patterns, was assessed using ultrasound. The preliminary diagnosis issued was of acute medical abdomen with hepatic space-occupying lesion considered amebic liver abscess or liver tumor, moderate hypochromic microcytic anemia, and malnutrition with short stature. During the case evolution, a frst computerized tomography exploration was necessary in order to exploit the capacity of this imaging tech- nique to scan an abscess as a peripheral pseudo-capsule showing rim enhancement. Nevertheless, this theoretical shape associated with abscesses on computerized tomog- raphy scans was unable to verify in this study. At this point, the mixed-echo patterns of the preliminary ultrasound study and the imprecision of the computerized tomography scan to categorize the lesion as an abscess or a tumor, do not allow establishing a defnitive diagnosis. A management based on antibiotic therapy is then proposed. The progression of the space-occupying lesion was performed using ultrasound and computerized tomography scans during the clinical evolution. The imaging controls probe a slight decrease of the liver le- sion, which is diagnosed as a liver abscess. Percutaneous transhepatic drainage was performed. An amoebic liver ab- scess in resolution was fnally diagnosed. |

El paciente ingresó en la Unidad de Pediatría del Hospital Central San Cristóbal, Táchira, Venezuela, con dolor abdomi- nal y febre. Se evaluó un abdomen plano y una hepatomega- lia palpable de 3 cm por debajo del reborde costal derecho. La ecografía abdominal reveló un hígado agrandado en el área anterosuperior derecha. Se evaluó una lesión ocupan- te de espacio redondeado, predominantemente sólida, con patrones de eco mixto, mediante ultrasonido. El diagnóstico preliminar emitido fue de abdomen médico agudo con lesión hepática ocupante de espacio considerada absceso hepático amebiano o tumor hepático, anemia microcítica hipocrómica moderada y desnutrición con talla baja. Durante la evolución del caso, fue necesaria una primera exploración de tomogra- fía computarizada para explotar la capacidad de esta técnica de imagen para escanear un absceso como una pseudocáp- sula periférica que muestra el borde realzado. Sin embar- go, esta forma teórica asociada con abscesos en tomografía computarizada no se pudo verifcar en este estudio. En este punto, los patrones de eco mixto del ultrasonido preliminar y la imprecisión de la tomografía computarizada para clasifcar la lesión como un absceso o un tumor, no permiten estable- cer un diagnóstico defnitivo. Se propone terapia con antibió- ticos. La progresión de la lesión ocupante de espacio se rea- lizó mediante ecografía y tomografía computarizada durante la evolución clínica. Los controles de imágenes refejan una ligera disminución de la lesión hepática, que se diagnostica como un absceso hepático. Se realizó drenaje transhepático percutáneo. Finalmente se diagnosticó un absceso hepático amebiano en resolución.pdfengSociedad Venezolana de Farmacología y de Farmacología Clínica y TerapéuticaAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Archivos Venezolanos de Farmacología y Terapéutica AVFTVol. 39, N° 4, (2020)Liver abscessLiver tumorAmebiasisAntibiotic therapyUltrasoundComputerized tomographyAbsceso hepáticoTumor de hígadoAmebiasisTerapia antibióticaUltrasonidoTomografía computarizadaLiver abscess mimicking tumor: A pediatric case reportAbsceso hepático que simula un tumor: reporte de un caso pediátricoinfo:eu-repo/semantics/articleArtículo científicohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Kelley, W.
