Chest Wall Cysticercosis
Chest Wall Cysticercosis
Clinical History
A 34-year-old male presented with a slowly enlarging, mildly painful swelling over the right anterior chest wall for three weeks. The patient reported localized tenderness without fever or history of trauma. Ultrasound examination of the chest wall soft tissues was performed for further evaluation.
Ultrasound Findings
Ultrasound examination demonstrates a well-defined cystic lesion within the subcutaneous soft tissues of the right anterior chest wall,. An eccentric echogenic mural nodule is identified within the cyst, representing the scolex. Mild surrounding hypoechoic inflammatory changes and soft tissue edema are present. No significant internal vascularity is seen within the cyst; however, minimal peripheral vascularity is demonstrated on Color Doppler imaging. No associated abscess collection or underlying rib abnormality is identified.

Report Line
A well-defined cystic lesion measuring approximately 1.5 × 1.2 × 1.0 cm is identified within the subcutaneous soft tissues of the right anterior chest wall. An eccentric echogenic mural nodule (scolex) is visualized within the cyst. Mild surrounding inflammatory changes are present. Findings are highly suggestive of soft tissue cysticercosis.
Impression
Chest wall soft tissue cysticercosis characterized by a cyst containing an eccentric scolex.
Mild surrounding inflammatory reaction is present. No abscess formation identified.
Go To Table
Mild surrounding inflammatory reaction is present. No abscess formation identified.
Recommendation
Clinical correlation is recommended. Evaluation for additional sites of involvement, particularly neurocysticercosis, may be considered when clinically indicated. Medical management with antiparasitic therapy and anti-inflammatory medication should be guided by the treating physician. Follow-up ultrasound may be performed to document treatment response.
Key Learning Points
- Cysticercosis is caused by larval infection of Taenia solium.
- The most characteristic ultrasound finding is a cyst containing an eccentric echogenic scolex.
- Soft tissue cysticercosis may present as a painful or painless palpable swelling.
- Surrounding inflammatory edema may be present and can mimic an abscess or soft tissue tumor.
- Color Doppler usually demonstrates absent internal vascularity with occasional mild peripheral hyperemia.
- Ultrasound is often sufficient to establish the diagnosis when the scolex is clearly visualized.
- Differential diagnoses include epidermoid cyst, abscess, hematoma, lymph node, and soft tissue neoplasm.
