Excessive right subdiaphragmatic fat: a potential diagnostic pitfall

Area of Science:

• Radiology
• Medical Imaging
• Gastroenterology

Background:

• Excessive fat in the subdiaphragmatic region can mimic various pathological conditions.
• Differential diagnosis is crucial for accurate patient management.

Observation:

• Six patients with excessive subdiaphragmatic fat were evaluated.
• Imaging modalities included plain radiography, computed tomography (CT), and ultrasound.

Findings:

• Plain radiographs showed a radiolucent area between the liver and diaphragm in all cases.
• Computed tomography (CT) is the optimal imaging modality for diagnosis.
• Ultrasound and plain radiographs can also confidently identify this condition.

Implications:

• Accurate identification of excessive subdiaphragmatic fat prevents unnecessary invasive procedures.
• Understanding imaging characteristics aids radiologists in differentiating benign fat from pathology.
• This finding highlights the importance of recognizing normal anatomical variants in diagnostic imaging.
