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
Skin & Subcutaneous Tissue: Skin thickness appears normal. Subcutaneous tissue shows normal echotexture with no edema or collection.
Muscle Layers:
A well-defined hyperechoic lesion is noted within the latissimus dorsi muscle plane,
measuring approximately 5.6 × 2.8 cm.
The lesion demonstrates fatty echotexture with linear echogenic striations.
No invasion of adjacent structures or muscle disruption is seen.
Fascial Planes:
Fascial layers are intact with no evidence of fluid tracking or disruption.
Soft Tissue:
No additional focal soft tissue mass, cystic lesion, or abscess is seen.
Vascularity:
No internal vascularity is observed within the lesion on Doppler evaluation.
Impression: Features are suggestive of intramuscular (latissimus dorsi muscle) lipoma.
Recommendation: Clinical correlation is advised. MRI may be considered for further evaluation of extent and confirmation. Follow-up is recommended if symptomatic or showing interval increase in size.
Kindly Note:
Limitations / Technical Factors:
Ultrasound evaluation is limited for deep-seated lesions and bony structures.
Clinical correlation and further imaging (MRI / CT) may be required
depending on clinical suspicion.
