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 mass in a pediatric patient / Suspected soft tissue lesion.
Location: Right lateral dorsal wall, within the subcutaneous or intramuscular plane. Soft Tissue: A well-defined lobulated hyperechoic soft tissue lesion is seen, measuring approximately 5.5 × 3.0 cm. The lesion demonstrates internal septations with mild heterogeneity. Minimal internal vascularity may be present on Doppler evaluation. No invasion of adjacent structures or deep fascial disruption is noted. Muscle Layers: Adjacent muscle planes appear preserved with no definite infiltration. Fascial Planes: Fascial layers are maintained without evidence of disruption or deep extension. Vascularity: Minimal internal vascularity is noted on Doppler evaluation.
Impression: Features are suggestive of lipoblastoma in the right lateral dorsal wall, in appropriate clinical setting (typically seen in infants and young children).
Recommendation: Clinical correlation is advised, particularly with patient age. MRI may be considered for assessment of lesion extent and deeper involvement. Surgical excision with histopathological confirmation is recommended.
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.

End of Case Study
You have reached the end of this Lipoblastoma – 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
“Lipoblastoma – Dorsal Wall (Back Lump) on Ultrasonography (USG)”
has been prepared solely for educational and academic purposes.
The findings demonstrate a well-defined lobulated soft tissue lesion located in the
subcutaneous or intramuscular plane of the dorsal wall, showing predominantly
hyperechoic appearance with internal septations and mild heterogeneity,
consistent with a lipoblastoma.
Lipoblastoma is a benign tumor arising from embryonic fat, typically seen in
infants and young children. On ultrasound, it may appear as a lobulated,
fatty lesion with internal septations and variable vascularity.
Ultrasonography is useful for initial evaluation; however,
MRI is recommended for assessment of lesion extent,
and histopathological confirmation is required for definitive diagnosis.
These findings are intended for learning and demonstration only.
Definitive diagnosis and management require clinical correlation and appropriate medical consultation.
