Technique:
Real-time ultrasound examination of the dorsal wall was performed using a
high-frequency linear transducer (7–12 MHz).
Systematic evaluation of the posterior thoraco-lumbar region was carried out
in longitudinal and transverse planes.
Skin, subcutaneous tissue, muscle layers, and underlying soft tissue structures
were assessed.
Clinical indication:
Back swelling / Pain / Palpable dorsal wall lump / Suspected soft tissue lesion.
Location: An ill-defined soft tissue mass is noted in the right lateral dorsal wall involving the deep soft tissue and intermuscular plane. Soft Tissue Lesion: An ill-defined heterogeneous hypoechoic mass is seen measuring approximately 6.8 × 4.1 cm. The lesion demonstrates irregular margins with infiltration into adjacent soft tissues. Internal heterogeneity with focal areas suggestive of necrosis is noted. Muscle / Fascial Planes: Adjacent intermuscular and fascial planes appear infiltrated. No definite calcification is identified. Calcification / Necrosis: Focal internal heterogeneity suggests possible necrotic change. No calcification is seen. Vascularity: Moderate internal vascularity is noted on Doppler evaluation.
Impression: Ill-defined heterogeneous infiltrative soft tissue mass involving the right lateral dorsal wall with moderate internal vascularity and possible necrotic change. Features are suspicious for fibrosarcoma.
Recommendation: Urgent MRI is recommended for assessment of local extent and staging. Histopathological confirmation is essential. Oncological referral is advised for further evaluation and management.
Kindly Note:
Limitations / Technical Factors:
Ultrasound evaluation may be limited in characterization of deep soft tissue masses
and assessment of complete locoregional extension.
MRI correlation and histopathological evaluation are essential
for definitive diagnosis and staging.
