Male; 44 years old. Reason: Ultrasound of Soft Module Mass over L5-S (Sacrum). Two bumps in lower back for three months. Fluctuating in Size - ? Cyst. In the subcutaneous tissues of the left lower back is a calcified lesion measuring 1.1 cm in craniocaudal dimension. Due to the heavy calcification this lesion cannot be further characterized by ultrasound. Similarly, in the subcutaneous tissues of the right lower back a calcified lesion measures 2.1 cm craniocaudal dimension and cannot be further characterized due to heavy calcification.In the midline of the lower back/sacrum is a subcutaneous solid nodule with no vascularity on color Doppler. This measures 2.7 x 1.9 x 0.7 cm.
1.Calcified lesions in the subcutaneous tissues superior to the left and right buttocks cannot be further characterized by ultrasound.2.Midline subcutaneous lesion may represent a lipoma however this lesion is considered indeterminate on ultrasound. If clinically indicated, MRI may be considered for further evaluation.
