ABSTRACT

Introducción: el absceso epidural posterolateral y la compresión radicular es una rara complicación del absceso retrofaríngeo (ARF). Se realizó el reporte de un caso con esta complicación extremadamente rara. Método: reporte de caso y revisión de la literatura (estudios radiológicos, historia y hallazgos clínicos). Se firmó consentimiento del paciente para la publicación. Resultados: paciente de 33 años remitido a nivel terciario de atención con un cuadro clínico de cervicalgia, odinofagia y fiebre. La tomografía axial computarizada (TAC) y la resonancia magnética nuclear (RMN) mostraron una colección retrofaríngea con compromiso epidural en el espacio medular cervical; en el examen físico se encontró odinofagia, cervicalgia, fiebre y pérdida de la fuerza muscular en el miembro superior derecho. El paciente fue llevado a manejo quirúrgico por otorrinolaringología y ortopedia para el drenaje de la colección; además, se le administró antibioticoterapia con cefepime y clindamicina por 21 días con buenos resultados; se consideró que el origen del absceso era idiopático. Conclusiones: el absceso epidural y la compresión radicular secundarias a un ARF es una rara y potencialmente mortal complicación de esta patología, con secuelas importantes en el paciente que la padece, que requiere un manejo médico-quirúrgico. En nuestro caso el manejo fue interdisciplinario, ya que integró otorrinolaringología, ortopedia, infectología y fisioterapia, lo que resultó en una evolución satisfactoria del paciente.


Introduction: posterolateral epidural abscess and radicular compression is a rare complication of retropharyngeal abscess (RFA), a case report with this extremely rare complication was made. Method: case report and review of the literature (radiological studies, clinical history, clinical findings) patient's consent was signed for the publication. Results: a 33-year-old patient referred at the tertiary care level with a clinical picture of cervicalgia, odynophagia and fever; CT and MRI showed retropharyngeal collection with epidural involvement in the cord cervical space, physical examination, odynophagia, cervicalgia, fever and loss of muscle strength in the right upper limb. Led to surgical management by ENT and orthopedics column for drainage of the collection; antibiotic therapy with cefepime, clindamycin for 21 days with good results; It was considered of idiopathic origin. Conclusions: epidural abscess and root compression secondary to an RFA is a rare and potentially fatal complication of this pathology with important sequelae in the patient, which requires medical-surgical management, in our case the management was integrated interdisciplinary otolaryngology, orthopedics, infectology, physiotherapy , with satisfactory evolution in the patient.

ABSTRACT

La piomiositis primaria es la infección bacteriana por vía hematógena del músculo estriado. Está relacionada con factores de riesgo como HIV/sida y otras enfermedades inmunodepresoras, pudiendo estar asociados a factores locales de estrés muscular. El agente etiológico más frecuente es Staphylococcus aureus. Su retardo diagnóstico puede ocasionar una evolución fatal. En esta serie se evaluaron 32 pacientes con piomiositis primaria diagnosticados por ecografía. El factor de riesgo más frecuente fue el HIV/sida (61%). Los factores locales se detectaron en 21 casos (66%): en primer lugar, la práctica de futbol. La forma monofocal se observó en 19 (59%) los músculos más frecuentemente afectados fueron cuádriceps, gemelos y psoas. Se obtuvieron muestras para estudio bacteriológico en 30 casos, 27 de material del absceso y 22 hemocultivos. En los 30 casos se aisló el agente etiológico. El Staphylococcus aureus representó el 83.3% (25 casos) y Escherichia coli, Nocardia spp., Streptococcus agalactiae, Micobacteria no tuberculosa y Pseudomonas aeruginosa fueron aislados en un caso cada uno. Recibieron tratamiento quirúrgico 17 pacientes, punciones aspirativas, 9; antibióticos solamente, 4. Presentaron buena evolución 28 de los 30 pacientes (93.3%), óbitos, 2 (6.6%); desconocida, 2. Este estudio concluyó que: ante la etiología diversa y cambiante de las piomiositis primarias es importante reconocer el agente involucrado y su sensibilidad antibiótica. La ecografía realiza la evaluación en tiempo real y puede ser utilizada como guía de punción facilitando el diagnóstico inmediato. Esto la diferencia de otras técnicas, transformándola en un método de primera línea para el estudio de esta enfermedad.


Primary pyomyositis is a bacterial infection of striated muscle which is acquired by hematogenous route. It is related to risk factors such as HIV/aids and other immuno suppressing diseases, and can be associated with local muscle stress factors. The most frequent etiology is Staphylococcus aureus. Its diagnostic delay may cause a fatal evolution. In this series 32 patients with primary pyomyositis diagnosed by ultrasound were evaluated. The most frequent risk factor was HIV/aids (61%). Local factors were detected in 21 (66%) cases: first, the practice of football. The monofocal form was observed in 19 (59%), the most commonly affected muscles were quadriceps, calves and psoas. Samples for bacteriological study were obtained in 30 cases, 22 blood culture and 27 abscess materials. In 30 cases the etiologic agent was isolated. Staphylococcus aureus accounted for 83.3% (25 cases) and Escherichia coli, Nocardia spp., Streptococcus agalactiae, nontuberculous mycobacteria, Pseudomonas aeruginosa were isolated in one case each. Seventeen patients received surgical treatment, aspirative punctures, 9; antibiotics alone, 4. Twenty eight (93.3%) patients had a good evolution; deaths, 2 (6.6%); unknown, 2. Main conclusions of this study were: due to the diverse and changing etiology of the primary pyomyositis it is important to recognize the etiological agent involved and their antibiotic susceptibility.The ultrasound performed the study in real time so it can be used to guide the puncture and to facilitate the immediate diagnosis. This makes the difference with other techniques and transforms it into a first-line method for the study of this disease.

ABSTRACT

Osteomyelitis was induced in 45 male dogs by inoculating hemolytic strain of Staphylococcus aureus alone into the tibial marrow cavity. Clinical, radiological and bacteriological studies were conducted to evaluate the progress of disease up to 15 weeks. Clinical signs consisted of localized soft tissue swelling, pain, pyrexia and lameness which later developed an open wound with purulent exudation. Predominant radiographic features were extensive periosteal reaction, cortical lysis, new bone formation, frequent development of sequestrum and formation of localized abscess pockets in advanced cases. Staphylococci were recovered from the tibial marrow cavity for as long as 15 weeks after onset of the infection.
