Dorsal Wall Ultrasound
Technique:
Real-time ultrasound examination of the posterior lumbar dorsal wall was performed using a
high-frequency linear transducer (7–12 MHz), supplemented with a low-frequency curvilinear probe
where required for deeper evaluation.
Systematic assessment of the paraspinal and posterior abdominal wall region was performed in
longitudinal and transverse planes.
Skin, subcutaneous tissue, muscle layers, and deeper soft tissue structures were evaluated.
Clinical indication:
Suspected soft tissue lesion
Skin & Subcutaneous Tissue:
Skin thickness appears normal.
Subcutaneous tissue shows normal echotexture with no edema or collection.
The lesion demonstrates homogeneous fatty echotexture with fine internal linear striations. No surrounding muscle invasion or architectural distortion is identified. Fascial Planes: Fascial planes appear preserved with no evidence of disruption or fluid tracking. 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 hyperechoic lesion involving the posterior extension of the psoas muscle,
showing sonographic features suggestive of a lipoma.
Features are suggestive of intramuscular (psoas muscle) lipoma.
Recommendation: Clinical correlation is advised. Due to deep location and limited ultrasound evaluation, MRI is recommended for further characterization and extent assessment. Follow-up is advised if symptomatic or increasing 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.

End of Case Study
You have reached the end of this Levator Scapulae Muscle Lipoma – Back Lump (Dorsal Wall Ultrasound Case Study).
This evaluation was performed using Ultrasonography (USG), allowing real-time assessment of superficial and deep musculoskeletal soft tissue structures.
Content is intended for educational, training, and clinical reference purposes only.
Declaration:
I, R. K. Mouj, declare that the material presented in this case study titled
“Levator Scapulae Muscle Lipoma – Dorsal Wall (Back Lump) on Ultrasonography (USG)”
has been prepared solely for educational and academic purposes.
The findings demonstrate a well-defined, hyperechoic lesion located within the
intramuscular plane of the levator scapulae muscle, extending from the
upper cervical region to the superior angle of the scapula, deep to the trapezius muscle,
consistent with an intramuscular lipoma.
The lesion shows homogeneous fatty echotexture with fine internal linear striations,
oriented parallel to muscle fibers, with absence of internal vascularity on Doppler imaging.
No surrounding soft tissue infiltration or aggressive features are identified.
Ultrasonography is a reliable, non-invasive modality for evaluating both superficial and deep soft tissue masses,
aiding in differentiation of benign lesions such as lipoma from other pathological conditions.
These findings are intended for educational and demonstration purposes only.
Definitive diagnosis and management require clinical correlation and appropriate medical consultation.
