Adenoma cortical adrenal small functional: treatment with percutaneous acetic acid injection CT - ratio on three cases. A specific subtype under this entity is adrenocorticotropin independent macronodular adrenocortical hyperplasia (AIMAH).. This is a 36-year-old female patient who had been consulting for secondary amenorrhea and developing asthenia for 4 months. Recent studies have shown that primary bilateral macronodular adrenal hyperplasia is caused by combined germline and somatic mutations of the ARMC5 gene. Primary macronodular adrenal hyperplasia Description Primary macronodular adrenal hyperplasia (PMAH) is a disorder characterized by multiple lumps (nodules) in the adrenal glands, which are small hormone-producing glands located on top of each kidney. (C) Clustering based on differential gene expression of G-protein coupled receptor activity. Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a highly heterogeneous entity. It is, however, responsible for definitive adrenal insufficiency. For a discussion of genetic heterogeneity of ACTH-independent macronodular adrenal hyperplasia .
