Background Prevertebral calcific tendinitis results from calcium hydroxyapatite crystal deposits in the longus colli muscles, which induce symptoms similar to some surgically-treated conditions, such as retropharyngeal abscesses. Imaging techniques are critical for accurate diagnosis. Purpose To describe the computed tomography (CT) findings associated with prevertebral calcific tendinitis. Material and Methods Retrospective analysis performed in an 18-month period, searching for patients with neck CT and reports with diagnosis of “calcific longus collis tendinitis” or “prevertebral calcific tendinitis”. CT images and clinical data available in the medical records were analyzed. Results One hundred and thirty-four examinations were performed in the period studied. Nine patients who fulfilled inclusion criteria were identified and their CT imaging characteristics are presented. Six presented with calcific deposits in the right longus colli muscle. CT matched the clinical pain lateralization in all cases. Eight patients had no significant enhancement post injection of contrast media. Conclusion Prevertebral calcific tendinitis is a cause of acute cervical pain that clinically mimics a retropharyngeal abscess, however on neck CT has a characteristic appearance. Correct identification of this pathologic condition will help avoiding unnecessary invasive procedures.
El flegmón (celulitis) y el absceso periamigdalino son infecciones difusas o una colección ubicada entre la cápsula fibrosa de la amígdala palatina, las fibras horizontales del músculo constrictor superior de la faringe y las verticales del músculo palatofaríngeo. Constituye la infección de tejidos y espacios profundos del cuello más frecuente.Material y método: Revisión retrospectiva de las fichas de pacientes adultos y niños hospitalizados con diagnóstico de absceso o flegmón periamigdalino en el Servicio de Otorrinolaringología del Hospital San Juan de Dios entre los años 1995 y 2001.Resultados y discusión: Se analizaron 124 pacientes. Se observó un acierto del diagnóstico clínico en 85,5% de los casos. El 100% de los pacientes presentó evolución clínica favorable según la modalidad terapéutica indicada. La mayoría de los pacientes con absceso periamigdalino fue tratado con drenaje y antimicrobiano, y los con flegmón periamigdalino con antimicrobiano. El antibiótico utilizado con mayor frecuencia fue penicilina. No existió diferencia significativa al usarlo en esquema asociado. La penicilina sódica sigue siendo un antimicrobiano de primera elección para este cuadro y no requeriría de asociaciones; dosis de 3 millones de UI cada 6 horas endovenosa pueden ser recomendadas. El tratamiento en el Servicio de Otorrinolaringología del Hospital San Juan de Dios se ciñe a las reglas internacionales.Palabras Clave: Absceso periamigdalino, flegmón periamigdalino, diagnóstico, cultivo, tratamiento. SUMMARYCellulitis and abscess peritonsillar are a diffuse infection or a collection located between the fibrous capsule of the palatine tonsil, the horizontal fibers of the superior constrictor muscle of the pharynx and the vertical ones of the palatopharyngeal muscle. It is most frequently an infection of deep tissue and spaces of the neck.Material and method: Retrospective review of the index cards of adult patients and children hospitalized with diagnosis of abscess or peritonsillar phlegmon cellulitis at the Otolaryngology Service of Hospital San Juan de Dios between years 1995 and 2001.
