Summary
This study highlights two cases of large abdominal lipomas in women, presenting with abdominal pain and masses. Surgical removal was successful, confirming lipomas as the diagnosis for these benign tumors.
Area of Science:
- Abdominal Imaging
- Surgical Pathology
- Oncology
Background:
- Lipomas are benign tumors composed of adipose tissue.
- Large abdominal lipomas can present as asymptomatic or symptomatic masses, mimicking malignant neoplasms.
- Accurate diagnosis and surgical management are crucial for patient outcomes.
Observation:
- A 72-year-old woman presented with a large, solid, hyperechogenic mass in the right upper quadrant, initially suspected as a liver tumor.
- A 60-year-old woman presented with a similar mass in the right epigastrium, diagnosed preoperatively as an abdominal tumor.
- Both cases involved large masses with calcifications, causing displacement of adjacent organs, as visualized by ultrasound and CT scans.
Findings:
- Histopathological examination confirmed both masses as lipomas.
- Imaging characteristics, including Hounsfield units and calcifications, were detailed for both lipomas.
- Surgical excision was performed successfully in both cases, with no immediate complications reported.
Implications:
- This report underscores the importance of considering lipomas in the differential diagnosis of large abdominal masses, even with concerning imaging features.
- Surgical intervention is an effective treatment for symptomatic or large abdominal lipomas.
- Further research into the specific imaging markers differentiating benign lipomas from other abdominal tumors could improve diagnostic accuracy.
