To assess the yield of US in the study of salivary glands and other organs involved in post-pubertal mumps.
We examined 68 patients with serologically proven post-pubertal mumps (age range 14-34 years). All patients were symptomatic, with fever and salivary gland swelling in 25 cases, marked hyperamylasemia in 32, epigastric pain in 9, unilateral scrotal swelling and/or pain in 19 cases and acute bronchitis in 1 case. All patients underwent US of salivary glands, neck lymph nodes, abdomen and scrotum with 48 hours of admission.
Salivary glands: Parotid and submandibular glands showed normal echotexture in all patients. The parotid glands also showed multiple hypeoechoic intraparenchymal lymph nodes which were, ovoid or rounded, with smooth margins and a central hyperechoic area, with diameter ranging 3-14 mm (mean 5.4). No intraparenchymal lymph nodes were observed in submandibular glands. Neck: All patients had enlarged submandibular lymph nodes (maximum diameter ranging 5-22 mm; mean 11 mm); swelling was always bilateral and it was symmetric in 19/68 patients (30%) versus asymmetric because of prevailing right side involvement (more numerous and bigger nodes) in the other 47/68 cases (70%). All lymph nodes showed a benign pattern, with an ovoid or elongated shape, homogeneous hypoechoic echotexture and a hyperechoic hilum. Abdomen: The pancreas showed normal volume and normal parenchymal echotexture in all patients. Liver and spleen were always normal. Testes: US showed mild unilateral hydrocele in 10 cases, hydrocele and unilateral swelling of epidymis in 5 cases, hydrocele and swelling of both epidymis and didymis with inhomogeneous echotexture because of intraparenchymal hypeoechoic areas in 2 cases. There were no US changes in 2 cases.
US of the salivary glands shows a specific pattern in post-pubertal mumps which has never been reported for other salivary gland diseases. In contrast US signs in other organs are not specific.
评估超声检查在青春期后腮腺炎累及的唾液腺及其他器官研究中的诊断价值。
我们检查了68例血清学确诊的青春期后腮腺炎患者（年龄范围14 - 34岁）。所有患者均有症状，其中25例出现发热和唾液腺肿胀，32例有明显高淀粉酶血症，9例有上腹部疼痛，19例出现单侧阴囊肿胀和/或疼痛，1例有急性支气管炎。所有患者在入院48小时内接受了唾液腺、颈部淋巴结、腹部及阴囊的超声检查。
唾液腺：所有患者腮腺和颌下腺回声纹理正常。腮腺还显示多个实质内高回声淋巴结，呈椭圆形或圆形，边界光滑，中央为高回声区，直径3 - 14毫米（平均5.4毫米）。颌下腺未观察到实质内淋巴结。颈部：所有患者颌下淋巴结肿大（最大直径5 - 22毫米；平均11毫米）；肿胀均为双侧性，19/68例患者（30%）对称，其余47/68例患者（70%）因右侧受累为主（淋巴结更多、更大）而不对称。所有淋巴结均表现为良性特征，呈椭圆形或长形，均匀低回声纹理，有高回声髓质。腹部：所有患者胰腺体积正常，实质回声纹理正常。肝脏和脾脏始终正常。睾丸：超声检查显示l0例有轻度单侧鞘膜积液，5例有鞘膜积液和附睾单侧肿胀，2例有鞘膜积液及附睾和睾丸肿胀，实质内高回声区导致回声不均匀。2例未发现超声改变。
青春期后腮腺炎患者唾液腺的超声表现具有特定模式，这在其他唾液腺疾病中从未有过报道。相比之下，其他器官的超声表现不具有特异性。
