Complicated traumatic pulmonary pseudocyst: a case report

Abstract

A traumatic pulmonary pseudocyst (TPP) is an uncommon lung lesion that can occur due to blunt chest trauma. This condition is usually harmless and doesn't require medical treatment, but in rare cases, it is complicated by rupture of the lesion and hemothorax. We present the case of a 43-year-old man who fell from a height and suffered chest trauma. Imaging revealed a mass-like lesion and hemothorax, but after ruling out other diagnoses, he was diagnosed with complicated traumatic pulmonary pseudocyst. Over six months, the mass-like lesion shrank and disappeared entirely without any remaining scars. Proper diagnosis and differentiation from other lung lesions are essential in cases of TPP. With conservative management and regular follow-up, the prognosis is generally reasonable.

The patient chest CT scans without contrast at admission, one month after admission, and six months after admission. Figures a, d, and f show the parenchymal view, while figures b, c, e, and g present the mediastinal view of the patient's chest CTs. The imaging reveals the spontaneous resolution of traumatic pulmonary pseudocyst (red arrow) and the complication of pseudocyst with hemothorax (yellow arrow).
