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.
KEYWORDSVenous vascular malformations; Abdominal wall; Ultrasound.Abstract Vascular anomalies are classified as vascular tumors and vascular malformations. Venous vascular malformations are the most common type of vascular malformation. They may be isolated or multiple and they rarely affect the trunk. The authors report a rare case of isolated venous vascular malformation of the abdominal wall with an emphasis on the related MRI and ultrasound (US) features.Sommario Le anomalie vascolari sono comunemente classificate in tumori di origine vascolare e malformazioni vascolari. Le malformazioni venose vascolari sono il tipo più comune di malformazioni vascolari.Esse possono presentarsi come isolate o multiple e raramente interessano il tronco. In questo articolo è riportato un caso di malformazione venosa vascolare isolata della parete addominale, le sue caratteristiche alla Risonanza Magnetica (RM) e all'ecografia. ª
Benign fibromatous tumor (BFT), also named ‘fibroma’, is a distinctive clinico-pathologic entity occurring in epididymis, spermatic cord, paratesticular structures, testis, renal peripelvis and rarely in renal parenchyma. We report the first case of a BFT (fibroma) located in the cortex of the kidney, and a critical review on the topic is provided. Tumor was found incidentally at autopsy as a small cortical nodule. With the increasing use of radiological imaging of the abdomen, it is likely that an increased number of incidental and asymptomatic benign renal tumors will be diagnosed. We underline that BFT (fibroma) should be considered in the preoperative differential diagnosis of renal cortical nodules.
