Abstract

Aryl hydrocarbon receptor-interacting protein (AIP) positive mutation patients are associated with an aggressive, inheritable form of acromegaly that responds poorly to first-generation somatostatin receptor ligands. We present a young female with AIP mutation-positive acromegaly with invasive pituitary macroadenoma that recurred after multiple transsphenoidal surgeries and failed to achieve biochemical remission with lanreotide therapy. Her disease was only controlled after three transsphenoidal surgeries, radiotherapy, and medical therapy that was switched over to pegvisomant. Following disease remission, she developed panhypopituitarism and worsening osteoporosis in her lumbar spine. Concurrently, she also desired pregnancy. Pegvisomant therapy was stopped after 3 years due to the gradual decline in IGF-I levels consistent with the development of post-acromegaly GH deficiency. Our case highlights the importance of careful and thoughtful evaluation of young AIP mutation-positive acromegaly patients by an expert multidisciplinary team so that a personalized treatment regimen can be implemented to achieve early disease remission and minimize tumor regrowth.
