[|Human|] Hi I am 48 yrs female 75kg.Hav 2 children 16 yrs and 15 yrs.Had problem with my 1st baby- I had blood transfusion-doctors almost lost me.2nd delivery no problem. I have fat accumulation at bottom of my left buttock-cant sit for long.Took 4 yrs to have it noticed-since has slow growth.No problems at the moment but doctor says need surgery as it may affect my renal area.What is the cause of this? and will it affect me if I get pregnant again before I get it removed?
[|AI|]  Hello and welcome to Chat Doctor, Ultrasound of the left buttock is required to know the type of lesion and its extent to surrounding structures. A growth in the left buttock region can involve the surrounding structures and thus have deleterious effect on surrounding structures. A fine needle aspiration cytology and/ or biopsy of the lesion may be required to know exact nature of the lesion. If the lesion turns out to be neoplastic, surgical excision of the mass may be done. Thanks and take care Chat Doctor.
