Summary
This case study details an unusual aneurysmal bone cyst (ABC) found in a patient's rib. Surgical resection was successful, highlighting ABCs as a rare but important consideration for rib tumors.
Area of Science:
- Orthopedic Surgery
- Skeletal Radiology
- Surgical Pathology
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign, expansile bone lesions, typically occurring in long bones and vertebrae.
- Rib ABCs are exceptionally uncommon, presenting diagnostic challenges due to their rarity and potential for mimicking other pathologies.
Observation:
- A 34-year-old female presented with left-sided rib pain and a radiographic abnormality in the 7th rib.
- Computed tomography (CT) identified an osteolytic lesion in the 7th rib.
- Positron emission tomography/CT (PET/CT) demonstrated minimal fluorodeoxyglucose uptake within the lesion.
Findings:
- Surgical resection of the 7th rib, including surrounding intercostal muscles, was performed with a 4 cm margin.
- Histopathological analysis confirmed the diagnosis of an aneurysmal bone cyst, characterized by blood-filled spaces and fibrous septa.
- The patient experienced an uncomplicated postoperative recovery.
Implications:
- This case underscores the importance of including aneurysmal bone cysts in the differential diagnosis for patients presenting with rib lesions.
- Accurate diagnosis and surgical management are crucial for favorable outcomes in rare skeletal tumors.
- Further research into the etiology and optimal management of extraskeletal ABCs may be warranted.
