Coughing can induce transdiaphragmatic intercostal hernias, a rare condition typically caused by trauma. This study details three such cases, showcasing imaging findings for this uncommon hernia type.
Area of Science:
- Medical imaging
- Thoracic surgery
- Diagnostic radiology
Background:
- Transdiaphragmatic intercostal hernia (TIH) is a rare condition.
- TIH is predominantly associated with traumatic injuries, both blunt and penetrating.
- Spontaneous or non-traumatic etiologies for TIH are infrequently reported.
Observation:
- Three distinct cases of TIH were observed.
- All cases were spontaneously induced by severe coughing episodes.
- The hernias involved protrusion through the intercostal spaces into the thoracic cavity.
Findings:
- Radiography, ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging were utilized.
- Imaging demonstrated characteristic herniation of abdominal contents into the chest.
- Specific anatomical details and defect sizes were visualized across modalities.
Implications:
- Highlights a non-traumatic cause of TIH, emphasizing the role of increased intra-abdominal pressure.
- Demonstrates the utility of various imaging techniques in diagnosing TIH.
- Contributes to understanding the pathophysiology and diagnostic imaging of cough-induced hernias.

Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
