Liposarcoma (Low-Grade Myxoid, Recurrent) – Back Lump (Dorsal Wall Ultrasound)

Dorsal wll Ultrasound Case Study Case Study No: R-29

---

Dorsal Wall Ultrasound

---

Technique: Real-time ultrasound examination of the dorsal wall was performed using a high-frequency linear transducer (7–12 MHz). Detailed evaluation of the posterior soft tissue structures was carried out in longitudinal and transverse planes with grayscale and Doppler assessment.
Clinical indication: Post-operative swelling / Suspected recurrence of soft tissue neoplasm / Pain at previous surgical site.

---

Location: Lobulated soft tissue lesion is noted along the right lateral dorsal wall, involving the deep soft tissue and intermuscular plane at the site of prior surgery.

Soft Tissue Mass: A heterogeneous predominantly hypoechoic lobulated mass is identified measuring approximately 7.8 × 4.3 cm. The lesion demonstrates myxoid appearance with areas of cystic change and multiple internal septations. Margins & Extension: Margins appear partially ill-defined with extension along adjacent fascial planes. No definite osseous involvement is appreciated on sonographic evaluation. Vascularity: Mild to moderate internal vascularity is noted on Doppler imaging. Calcification / Necrosis: No calcification is seen within the lesion. Focal cystic / myxoid degenerative areas are present.

---

Impression: Features are suggestive of recurrent low-grade myxoid liposarcoma involving the right lateral dorsal wall at the previous surgical site.

Recommendation: MRI is strongly recommended for assessment of local extent and recurrence. Comparison with previous imaging studies is advised. Histopathological confirmation is essential. Oncological referral is recommended.

Kindly Note:

Limitations / Technical Factors:
Ultrasound evaluation may be limited in assessing the complete extent of deep soft tissue tumors and adjacent osseous or neural involvement.
MRI correlation is recommended for comprehensive characterization and treatment planning.
