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:
Suspected soft tissue lesion
Skin & Subcutaneous Tissue: Skin thickness appears normal. Subcutaneous tissue shows normal echotexture with no edema or collection.
Muscle Layers: In the right upper dorsal region, between the medial border of the scapula and spine, a well-defined hyperechoic lesion is noted within the rhomboid muscle plane (deep to trapezius), measuring approximately 4.3 × 2.0 cm.The lesion demonstrates homogeneous fatty echotexture with linear echogenic striations. No adjacent muscle infiltration or structural distortion 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 noted within the lesion on Doppler evaluation.
Impression:
Well-defined intramuscular hyperechoic lesion within the rhomboid muscles,
showing characteristic sonographic features of a lipoma.
Features are suggestive of intramuscular (rhomboid major/minor muscle) lipoma.
Recommendation: Clinical correlation is advised. MRI may be considered for further evaluation if required. 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.
