■探讨罕见部位木村病(KD)的临床和影像学特征。
■对其临床表现进行回顾性分析,实验室检查,5例罕见部位KD患者的影像学特征。所有成像数据,包括位置,数量,尺寸,均匀性,边界,和增强的病变外观由两名独立的放射科医生评估。
■在5名患者中,四人无症状,和一个经历局部皮肤瘙痒。4例累及上臂皮下结节,一个人在腹股沟区。主要表现为单发(3例)或多发(2例)皮下结节/肿块,3例患者伴有局部淋巴结肿大。四名患者的外周血中嗜酸性粒细胞计数升高。四名患者有血管流动空洞的病变;其中三人,病变也表现出明显的增强。值得注意的是,5岁患者的病变未显示血管血流空洞,但表现出显著增强.此外,两名患者在病灶周围出现水肿。
■上臂或腹股沟区域存在孤立或多个皮下结节/肿块,伴有淋巴结肿大,外周血嗜酸性粒细胞升高,并观察病变内的内部血管,可以帮助诊断在罕见的解剖位置发生的KD。
UNASSIGNED: To explore the clinical and imaging features of rare site Kimura\'s disease (KD).
UNASSIGNED: Retrospective analysis was conducted on the clinical manifestations, laboratory examinations, and imaging features of five patients with rare site KD. All imaging data, including the location, quantity, size, uniformity, boundary, and enhanced appearance of the lesion were evaluated by two independent radiologists.
UNASSIGNED: Of the five patients, four were asymptomatic, and one experienced localized skin itching. Four cases involved subcutaneous nodules in the upper arm, while one was in the inguinal region. The main manifestations were single (three cases) or multiple (two cases) subcutaneous nodules/masses, with three patients accompanied by local lymph node enlargement. Four patients exhibited elevated eosinophil counts in their peripheral blood. Four patients had lesions with vascular flow voids; in three of these, the lesions also showed prominent enhancement. Notably, the lesion in a 5-year-old did not show vascular flow voids but displayed significant enhancement. Additionally, two patients showed edema around the lesions.
UNASSIGNED: The presence of solitary or multiple subcutaneous nodules/masses in the upper arm or inguinal area, accompanied by lymph node enlargement, elevated eosinophils in the peripheral blood, and the observation of internal vascular within the lesion, can aid in the diagnosis of KD occurring in uncommon anatomical locations.
