“…However, as confi rmed by our present study, frequently a bronchogenic cyst has a high number of HU approaching those of solid tumors instead of the low density of water, expected in a cyst. Th is is explained by the fact that bronchogenic cysts can contain proteinaceous fl uid resulting in high HU seen on a CT scan [5,6]. Our fi ndings are confi rmed by previous studies that demonstrating that bronchogenic cysts frequently have high HU resembling those of soft-tissue or solid tumors [5,10].…”

Our fi ndings are confi rmed by previous studies that demonstrating that bronchogenic cysts frequently have high HU resembling those of soft-tissue or solid tumors [5,10]. On the other hand, McAdams et al found cysts with a radiographic density higher than 20 HU in 25 out of 62 patients [11].…”

“…Th e radiologist was not involved in the treatment and not aware of the fi ndings and follow-up of the patients. Lesions were considered cystic when the radiographic density was between 0 and 20 HU and solid if radiographic density was more than 20 HU, as reported before [5].…”

“…Th e content of the cyst can be serous or proteinaceous, the latter giving the cyst the appearance of a solid tumor [5,6]. Th erefore a defi nitive preoperative diagnosis is frequently diffi cult to obtain.…”

Schlussfolgerung: Bronchogene Zysten werden häufi g fälschlich in der CT als solider Tumor diagnostiziert. Wenn die CT inkonklusiv ist, kann mittels MRI oder Ultraschall (EUS) die Diff erentialdiagnose getroff en werden. Summary. Background:Bronchogenic cysts are congenital malformations and are often detected in asymptomatic patients as an incidental fi nding. Growth can cause compression of airways and vessels, resulting in clinical symptoms and possible complications. On computed tomography (CT) scans, bronchogenic cysts frequently have the appearance of a solid tumor. We describe diagnostic strategy and management for patients with bronchogenic cysts.Methods: Retrospective case study of 11 adults diagnosed with a bronchogenic cyst. Th e CT scan of all patients was revised and localization, size, Hounsfi eld Units (HU), and appearance (cystic or solid) of the lesions were reported. Lesions were arbitrarily considered cystic or solid when the radiographic density was below or above 20 HU, respectively.Results: Eleven adults with a bronchogenic cyst were followed for at least 2 years after diagnosis. Eight of 11 detected lesions were judged as a solid lesion, based on the radiographic density (in HU) on CT images. Nine of 11 patients were treated by surgical resection. Two asymptomatic patients were not operated and remained asymptomatic without enlargement of the cysts during 2 years follow-up. Complications of resection were postoperative bleeding (n = 1), recurrent pneumothorax (n = 1), and recurrence of the cyst (n = 1). No mortality was observed.Conclusion: Bronchogenic cysts are frequently mistaken for a solid mass on CT scans. Further diff erentiation can be made by MRI or EUS when CT is inconclusive.

“…The cysts occur most commonly within 2 cm of the carina (subcarinal; right paratraheal) but can occur anywhere in the mediastinum. They contain mucoid material of variable viscosity that causes CT attenuation to vary from that of water to soft tissue [9]. At MR, high-signal intensity is seen characteristically within cysts on T2-weighted image although variable signal intensities with different proportions of protein and/or hemorrhage in the cysts are observed on T1-weighted image [10] (Figs.…”
