ABSTRACT
El absceso del psoas es una enfermedad infrecuente en niños. Puede tener una presentación clínica inespecífica, ser de inicio insidioso y relacionarse o no con fiebre. El tipo más frecuente en pediatría es primario; sin embargo, en ocasiones, puede ser de origen secundario y asociarse a infecciones graves, como la osteomielitis, por lo que se requiere un alto índice de sospecha para detectarlo y tratarlo oportunamente. Presentamos un caso atípico de absceso del psoas con infiltración del cuerpo vertebral de L2 en un paciente masculino de 14 años previamente sano, sin antecedente de traumatismo ni fiebre al momento del ingreso. Se realizaron una radiografía y una ecografía, pero el diagnóstico se confirmó a través de una resonancia nuclear magnética de columna lumbosacra. Conhemocultivos positivos para Staphylococcus aureus meticilino resistente, completó 2 semanas de tratamiento antibiótico endovenoso y 4 semanas por vía oral con negativización de cultivos y resolvió por completo la sintomatología inicial.
Psoas abscess is a common disease in children. It can have a nonspecific clinical presentation, insidious onset and sometimes fever. The most common type in children is the primary one; however, it can sometimes be of secondary origin and associated with severe infections such as osteomyelitis so a high index of suspicion is required to detect and treat it promptly. We present an unusual case of psoas abscess with infiltration of the vertebral body of L2 in a 14 year old male patient previously healthy with no history of trauma or fever on admission. X-ray and ultrasound were performed but the diagnosis was confirmed by magnetic resonance imaging of the lumbosacral spine. With positive blood cultures for methicillin-resistant Staphylococcus aureus he completed 2 weeks of intravenous antibiotic therapy and 4 weeks of oral antibiotic therapy with blood cultures negativization and resolution of symptoms.

The authors present a case of disseminated granuloma inguinale with bilateral psoas abscesses. Infection with calymmatobacterium granulomatis is usually localized to the genital organs but rarely may be disseminated. A search of the literature revealed that only two cases of psoas abscesses due to calymmatobacterium granulomatis were previously reported.
Los autores presentan un caso de granuloma inguinal diseminado con abscesos bilaterales de psoas. La infección con calymmatobacterium granulomatis normalmente se localiza en los órganos genitales, y raramente se disemina. La literatura reveló sólo dos casos de abscesos de psoas debidos a calymmatobacterium granulomatis reportados con anterioridad.

We report a 25-year-old woman who presented with features of peritonitis. At laparotomy, the cause of the pyoperitoneum was found to be a left-sided ilio-psoas abscess. This was drained, but the patient continued to deteriorate with sepsis, and died on the fourth post-operative day.

Fifteen patients, nine males and six females, diagnosed with pyomyositis from 1988 to 1994, and followed for an average of 69.8 months, were reviewed. Excluding two children, the average age was 56.6 years. Eleven adults (73.3%) had underlying diseases. The lesions were multiple in five patients (33.3%) and a total of twenty-four muscle abscesses, including eleven extrapelvic and thirteen intrapelvic, were identified. When comparing extra- and intrapelvic pyomyositis, intrapelvic pyomyositis presents a diagnostic challenge requiring a high index of suspicion. Distinct clinical features such as local heat and painful swelling were all identified in extrapelvic pyomyositis, but they rarely (in only two of the thirteen lesions) emerged in intrapelvic pyomyositis. The average time from presentation to diagnosis was significantly longer in intrapelvic than in extrapelvic pyomyositis (1.4 vs 9.7 days). Although aspiration showed a high diagnostic rate in extrapelvic muscle abscesses, it was difficult to perform and was occasionally misinterpreted in intrapelvic cases. Routine X-rays were not helpful in making the diagnosis. CT scan was valuable because it provided positive diagnostic findings in all twelve patients who received one. The causative organisms in our patients were Staphylococcus aureus in eight (53.3%), Escherichia coli in three (20%), and Klebsiella in three (20%). Treatments consisted of parenteral antibiotics for all patients, image-guided aspiration in four patients, and surgical drainage in eleven patients. Two intrapelvic pyomyositis patients expired due to sepsis. At the completion of the study, twelve patients were asymptomatic without sequel, and one patient had a recurrence.
