Summary
This case report details an hourglass transmural lipoma, a rare fatty tumor, diagnosed in a 73-year-old male. Video-assisted thoracic surgery enabled complete resection of this intra- and extra-thoracic lipoma.
Area of Science:
- Thoracic Surgery
- Surgical Oncology
- Diagnostic Imaging
Background:
- A 73-year-old male presented with an abnormal chest shadow.
- Imaging revealed a well-defined fatty mass in the right 3rd intercostal portion, extending both intra- and extra-thoracically.
Observation:
- Computed tomography (CT) and magnetic resonance imaging (MRI) characterized the mass as a high-intensity fatty lesion.
- The imaging features were consistent with an hourglass-type transmural lipoma.
Findings:
- Histopathological examination confirmed an intramuscular lipoma, infiltrating type, measuring 6.5×4.5×3.0 cm.
- No evidence of malignancy was found, but infiltrating types necessitate careful examination due to recurrence risk.
Implications:
- Video-assisted thoracic surgery (VATS) proved effective for complete resection of the hourglass lipoma.
- Careful histological examination is crucial for infiltrating lipomas to prevent recurrence.
