[Bronchopulmonary sequestration presenting with flank pain]
Introduction:
Flank pain is a classical symptom in urological patients and can have various causes. We now present a case in which we were able to diagnose retroperitoneal bronchial sequestration as a very rare cause of flank pain.
Case Report:
In the work-up of left flank pain in a 37-year-old woman, a suprarenal mass, about 5 cm in diameter, was diagnosed in a CT scan. The patient underwent surgery and a pulmonary sequestration was identified histologically. This very rare differential diagnosis of suprarenal masses belongs to pulmonary malformations and normally is an asymptomatic accidental finding. Up to now, only few reports are documented in literature where pulmonary sequestration showed symptoms like flank pain. In this case, the pain seems to be due to mucus retention in the sequester. The literature on this disease is presented here.

Clinical Manifestations:
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
