In adults, congenital partial eventration of the diaphragm is usually asymptomatic and detected as an incidental chest radiographic finding during health check-up for other reasons. Any rise in intra-abdominal pressure due to underlying pulmonary diseases such as asthma or chronic obstructive pulmonary disease or abdominal conditions such as obesity and ascites may further distend the eventrated portion of the hemidiaphragm by pushing the abdominal contents upwards to fill the space and resulting in spurious radiologic appearance of a tumour. Computed tomography of the chest helps both in diagnostic confirmation of hemidiaphragmatic eventration and evaluation of lung parenchyma, mediastinal and subdiaphragmatic pathology.
