Following appropriate alpha- and beta-adrenergic blockade, the patient underwent adrenalectomy alone, with pathology confirming pheochromocytoma (PASS score 0) and negative margins. After multidisciplinary discussion involving Endocrinology, Urology, Genetics, and Oncology, nephrectomy was deferred given the indeterminate malignancy risk of the renal lesions and the known susceptibility to chronic kidney disease in TSC. This case illustrates how endocrine evaluation can fundamentally reorder surgical priorities, prevent unnecessary nephron loss, and ensure safe, individualized management in patients with genetic syndromes and concurrent adrenal and renal masses.
