Parotid abscess: mini-pictorial essay

Bacterial and viral infection of the intraparotideal and periparotideal lymph nodes, or of the glandular parenchyma, can lead to inflammatory and subsequently suppurative changes, which can result in abscess formation. Sonography allows a detailed morphological evaluation of the gland and has an important value, complementary to clinical examination, in the study of parotid inflammatory diseases. Specifically, sonography defines lesion's characteristics and, in a large number of cases, also its nature and, among the various imaging techniques, it is considered first-line imaging for the evaluation of parotid abscesses, which are characterized by hypo-anechoic lesions, with irregular margins. Color Doppler signals are peripheral to the abscess. If combined with color Doppler, sonography is important not only in diagnosis, but also in the evaluation of therapeutic efficacy and as a guide to the aspiration and drainage of abscesses. The rarity of some of these lesions led us to publish this mini-pictorial essay.Keywords Salivary glands Á Sonography Á Abscess Riassunto Le infezioni batteriche e virali dei linfonodi intraparotidei e periparotiedei, o del parenchima ghiandolare, provocano una risposta infiammatoria e successivamente possono portare a suppurazione e a formazione di ascessi. L'ecografia consente di effetuare una valutazione morfologica dettagliata della ghiandola ed ha un valore importante, complementare all'esame clinico, nello studio delle malattie infiammatorie parotidee, poichè permette di definire le caratteristiche della lesione e, in un gran numero di casi, anche la loro natura; di conseguenza, tra le diverse metodiche di imaging, l'ecografia viene considerata quella di primo livello per lo studio degli ascessi parotidei, che si presentano come lesioni ipo-anecogene, con margini irregolari. La valutazione mediante color-Doppler mostra la presenza di segnali periferici alla lesione ascessuale. Oltre all'importanza per la diagnosi, l'ecografia, in combinazione con il color-Doppler, è utile nel follow-up e per guidare gli esami bioptici ed il drenaggio delle lesioni. Poichè alcune di queste lesioni sono rare, abbiamo deciso di pubblicare questo mini-pictorial essay.

“…Furthermore, previous studies reported wound healing problems, which were not observed in our study [9]. Severe complications such as jaw osteomyelitis, temporal lobe abscess [23] craniocervical necrotizing fasciitis [24], descending mediastinitis [25], airway obstruction, septicemia, and septic shock [11,25,26] did not occur during the follow-up of our patients.…”

Background. A parotid abscess (PA) is a complication of an acute bacterial parotitis with a potentially life-threatening course. To date, data on the diagnosis and therapy of PA is sparse and mostly consists of case reports or case series. Therefore, this study aimed at comprehensively analyzing the microbiological spectrum and the therapeutic management in a bi-institutional setting. Methods. A retrospective clinical chart review was performed to identify all patients surgically treated for PA at two tertiary care centers in Germany. Data on demographics, clinical management and microbiological data including species identification, pathogenicity, type of antibiotic therapy, adjustment of antibiotics, antibiotic sensitivity testing, and smear test results were extracted. Intervention-related variables and etiology were analyzed for their statistical association with outcome variables. Results. Overall, 85 patients were included. Most patients (92.9%) underwent surgical incision. Around half of the patients (45.9%) were treated under local anesthesia. No facial nerve palsy was observed. The most frequently detected pathogens were Streptococci (n=23), followed by Staphylococcus aureus (n=6) including one case of methicillin-resistant Staphylococcus aureus. Most patients (68.2%) received an aminopenicillin +/- beta-lactamase inhibitor as empiric antibiotic therapy. In 6 cases the antibiotic therapy was modified after receiving the antibiogram. Four patients (5.2%) presented with recurrent PA. Etiology was idiopathic (42.4%) or obstructive, immunosuppressive, or tumorous (each 11.8%). Patients with a dental focus (p=0.007) had a longer duration of hospitalization. Chronic parotitis was associated with recurrence (p<0.001). Conclusion. The results show that the surgical therapy of PA under local anesthesia is safe. A dental examination should routinely be performed to rule out a dental focus. Obtaining a microbiological specimen in order to modify antibiotic therapy if necessary and a histopathological specimen to rule out a tumorous etiology is obligate.

“…6 The predisposing conditions of acute suppurative parotitis include dehydration, poor oral hygiene, dental infection, oral trauma, ductal obstruction, immunosuppression, certain drugs (anticholinergics and antihistamines), certain chronic diseases (Sjogren's syndrome and diabetes mellitus), malnutrition, pre-existing parotid Warthin's tumor, and sialolithiasis. 7,8 These precipitating factors generally seen in adults. Ductal stones not seen frequently in children as in our case, correlating the fact that parotid abscess formation is related with nonobstructive origin in most cases.…”

Acute suppurative parotitis and parotid gland abscess are infrequently seen in children. Ductal ectasis, primary parenchymal involvement or from a suppurative infection of the lymph nodes cause suppurative changes and leads to abcess formation. Various bacteria have been reported to be involved in the bacterial parotitis and abscesses; Staphylococcus aureus plays a major role both in adults, and in pediatrics patients, while in infant recurrent parotitis, Streptococcus spp. are the most recurrent isolated organisms. The pus may penetrates the capsule, invades the surrounding tissue, and extends into the deep fascial planes, backward into the external auditory canal as in our case, or outward into the facial skin.
