Dorsal Wall Ultrasound
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 / Palpable dorsal wall lump / Suspected soft tissue lesion.
Location: An ill-defined soft tissue lesion is noted in the right lateral dorsal wall, involving the deep subcutaneous and intermuscular plane. Soft Tissue Lesion: An ill-defined hypoechoic infiltrative lesion is seen measuring approximately 5.6 × 2.8 cm. The lesion demonstrates irregular margins with extension along fascial planes. Internal echotexture appears heterogeneous. Muscle / Fascial Planes: Mild infiltration of adjacent intermuscular and fascial planes is noted. No definite intramuscular fluid collection is identified. Necrosis / Calcification: No internal necrosis or calcification is seen. Vascularity: Mild internal vascularity is noted on Doppler evaluation.
Impression: Ill-defined infiltrative hypoechoic soft tissue lesion involving the right lateral dorsal wall with extension along fascial planes and mild internal vascularity. Features are suggestive of fibromatosis (desmoid tumor).
Recommendation: Further evaluation with MRI is recommended for extent assessment. Histopathological confirmation is advised. Surgical or oncological consultation may be considered.
Kindly Note:
Limitations / Technical Factors:
Ultrasound evaluation may be limited in assessing deep tissue extension
and complete infiltrative extent of soft tissue lesions.
MRI correlation and histopathological evaluation are recommended
for definitive characterization.
