Case courtesy : Dr. Cicy Kuncheria Welcare Hospital

Age: 61Yrs

Sex: Female

Complaints: Recurrent pain over left mid-clavicular region.

Case study: A smooth well defined soft tissue mass with fluid attenuation in the anterior mediastinum measuring ~3.9 x 2.9 x 3.4cm (TR XAP XCC).The lesion shows homogenous density.No calcification.

Images:

Conclusion : Smooth well defined anterior mediastinal mass lesion with fluid attenuation -imaging features are in favor of cystic mediastinal mass lesion. DD: Thymic cyst

Well circumscribed hypo to isodense (max. -15HU) oval shaped mass lesion measuring ~6.6 x 4.0 x 3.8 cm (CC x TR x AP) noted evolving from the left latissimus dorsi  and muscle involving the intramuscular space between subscapularis. No evidence of any bone involvement.

Case Discussion :
Well defined smooth solid hypo to iso-dense lesion in the left chest wall seen arising from the latissimus dorsi muscle.
The is lesion is seen as a solid mass with hypo-dense attenuation, however the lesion shows  typical fatty appearance.
The report was given as chest wall mass arising from left latissimus dorsi muscle.
Possible DD’s include:  1. Lipoma.   2. Liposarcoma  3.Schwannoma.

Conclusion: FNA done. Histopathology came as fat containing lesion and suggested Excision biopsy.
