Free pleuroperitoneal liquid movement indicating diaphragmatic tear

Area of Science:

• Radiology
• Trauma Surgery
• Gastroenterology

Background:

• Traumatic rupture of the diaphragm is often associated with intra-abdominal bleeding.
• Standard radiological assessments are crucial for diagnosing diaphragmatic injuries.
• The literature lacks descriptions of specific radiological signs related to this injury complex.

Observation:

• An unusual radiological feature was observed in a patient with traumatic diaphragmatic rupture and intra-abdominal bleeding.
• This feature manifested as free movement of fluid between the pleural and peritoneal cavities.
• The fluid movement was visualized on both supine and erect chest radiographs.

Findings:

• The observed radiological sign, free pleuroperitoneal fluid movement, has not been previously reported.
• This sign indicates a significant communication between the abdominal cavity and the pleural space.
• The presence of intra-abdominal bleeding likely contributes to this phenomenon.

Implications:

• This radiological sign may be more common than previously thought, given the frequent association of diaphragmatic rupture with abdominal injuries.
• The findings underscore the critical importance of obtaining both supine and erect chest radiographs in patients with multiple injuries.
• Recognition of this sign can aid in the prompt diagnosis and management of diaphragmatic rupture and associated intra-abdominal bleeding.
