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 Palpable lump.
Location: Right lateral dorsal wall, within the subcutaneous plane.
Skin & Subcutaneous Tissue: A well-defined hyperechoic lesion is seen measuring approximately 2.8 × 1.5 cm. The lesion appears slightly heterogeneous with internal vascular channels. Color Doppler shows increased vascularity. No surrounding infiltration is seen.
Muscle Layers: Underlying muscle planes appear normal in bulk and echotexture. No intramuscular extension is identified.
Fascial Planes: Fascial layers are intact with no disruption or deep extension.
Vascularity: No internal vascularity is noted on Doppler evaluation.
Impression: Features suggestive of angiolipoma.
Recommendation: Clinical correlation is advised. Surgical excision may be considered if painful. Histopathological confirmation is recommended.
Kindly Note:
Limitations / Technical Factors:
Ultrasound evaluation of dorsal wall soft tissue lesions may be limited in
deeply located components and in assessing internal vascular architecture in detail.
Small vascular channels within angiolipoma may not be fully characterized on ultrasound.
Further evaluation with MRI (preferred) or CT may be advised for
better tissue characterization, extent assessment, and surgical planning if clinically indicated.
Clinical correlation is recommended.

End of Case Study
You have reached the end of this Angiolipoma – Back Lump (Dorsal Wall Ultrasound Case Study).
This evaluation was performed using Ultrasonography (USG), allowing real-time assessment of superficial soft tissue structures.
Content is intended for educational, training, and clinical reference only.
Declaration:
I, R. K. Mouj, declare that the material presented in this case study titled
“Angiolipoma – Dorsal Wall (Back Lump) on Ultrasonography (USG)”
has been prepared solely for educational and academic purposes.
The findings demonstrate a well-defined, predominantly hyperechoic lesion located in the
subcutaneous plane of the dorsal wall, with possible internal vascular channels,
consistent with an angiolipoma.
On ultrasound, angiolipomas may show mild internal vascularity on Doppler evaluation,
distinguishing them from simple lipomas. These lesions are benign and commonly present
as painful subcutaneous nodules.
Ultrasonography is a reliable, non-invasive modality for evaluating superficial soft tissue masses,
aiding in differentiation between vascular and non-vascular fatty lesions.
These findings are intended for learning and demonstration only.
Definitive diagnosis and management require clinical correlation and appropriate medical consultation.
