Previous clinical studies have reported abdominal findings on ultrasonography or MRI in Puumala hantavirus-infected patients.
To determine if abdominal computed tomography (CT) can lead to a diagnosis of Puumala virus infection in the presence of a suggestive clinical picture.
CT findings were studied retrospectively in 30 patients who presented to the emergency department of two (Belgian) hospitals with serologically confirmed Puumala hantavirus infection.
The most frequent finding was perirenal fascial thickening (90%), followed by perirenal fat stranding (87%). Retroperitoneal fat stranding was found in 19 patients (64%) in the perivesical spaces along the fascia of the external iliac vessels with or without involvement of the presacral fat. Half of the patients had pelvic ascites, and pleural fluid was found in 7 of them. The right and left mean pole-to-pole kidney's lengths were respectively 125.7 mm and 127.8 mm in 28 patients.
Retroperitoneal fat stranding, perirenal fascial thickening and/or perirenal fat stranding were found in most patients with acute Puumala virus infection who have undergone CT. Although nonspecific, these findings may help to suggest Puumala hantavirus infection in the right clinical settings.
先前的临床研究已经报道了在感染普马拉病毒的患者的超声或 MRI 上出现腹部发现。
为了确定在存在提示性临床症状的情况下，腹部计算机断层扫描（CT）是否可以导致对普马拉病毒感染的诊断。
对在两家（比利时）医院急诊科就诊的 30 名经血清学证实感染普马拉汉坦病毒的患者进行回顾性 CT 发现研究。
最常见的发现是肾周筋膜增厚（90%），其次是肾周脂肪条纹（87%）。19 名患者（64%）在外髂血管筋膜旁的膀胱周围间隙中存在腹膜后脂肪条纹，伴或不伴骶前脂肪受累。一半的患者有盆腔腹水，其中 7 名患者有胸腔积液。28 名患者的右肾和左肾平均极-极长度分别为 125.7mm 和 127.8mm。
在接受 CT 检查的大多数急性普马拉病毒感染患者中，发现了腹膜后脂肪条纹、肾周筋膜增厚和/或肾周脂肪条纹。尽管这些发现是非特异性的，但它们可能有助于在适当的临床环境下提示普马拉汉坦病毒感染。
