Dr. Wadhawan said: “The patient came in with a body mass index of 48, diabetes mellitus, hypertension and other medical complications. He was a high-risk candidate for the surgery.” Speaking about the surgery, Dr. Wadhawan added that the team had to make a large incision on the abdomen due to the size of the tumour. “On removal, the tumour weighed 11.5 kg. We believe this is the largest adrenal myelolipoma. It was also highly vascular and attached to the right kidney, inferior vena cava and intestines. The biggest challenge was to salvage the patient’s right kidney, since his kidney functions were already affected due to diabetes and hypertension. Histopathology of the tumour confirmed the diagnosis of adrenal myelolipoma, ” he added. The largest tumour reported in India so far weighed 6 kg and was removed in 2003, while the largest adrenal adenoma, the differential diagnosis for adrenal tumours, removed in the world weighed 7.5 kg and was removed in 2013, according to a release issued by the hospital.
