Dorsal Wall Ultrasound

---

Technique: Real-time ultrasound examination of the dorsal wall was performed using a high-frequency linear transducer (7–12 MHz). Detailed grayscale and Doppler evaluation of the posterior soft tissue structures was carried out in longitudinal and transverse planes.
Clinical indication: Rapidly enlarging dorsal wall swelling / Pain / Suspicion of aggressive soft tissue neoplasm.

---

Location: Large soft tissue lesion is noted along the right lateral dorsal wall, involving the deep soft tissue and intermuscular plane.

Soft Tissue Mass: A large ill-defined heterogeneous predominantly hypoechoic mass is identified measuring approximately 9.2 × 5.6 cm. The lesion demonstrates irregular infiltrative margins with extension into adjacent soft tissue structures. Internal Characteristics: Marked internal heterogeneity is noted with areas of necrosis and hemorrhagic change. Loss of normal surrounding fat planes is evident. Vascularity: Prominent internal vascularity is demonstrated on Doppler imaging. Adjacent Structures: Infiltration into adjacent soft tissue and intermuscular planes is noted. No definite calcification is identified on current sonographic evaluation.

---

Impression: Features are highly suspicious for high-grade undifferentiated liposarcoma involving the right lateral dorsal wall.

Recommendation: Urgent MRI is recommended for staging and assessment of local extent. CT scan may be required for metastatic workup. Histopathological confirmation is mandatory. Immediate oncological referral is advised.

Limitations / Technical Factors:
Ultrasound evaluation has limited capability in assessing complete tumor extent, deep tissue involvement, and metastatic disease.
MRI / CT correlation is essential for comprehensive staging and management planning.
