Recurrent Cushing's Disease Associated with Nephrotic Syndrome

Abstract

A case of recurrent Cushing's disease with nephrotic syndrome due to membranoproliferative glomerulonephritis (MPGN) is presented. Functional pituitary adenoma recurred 6 years after transsphenoidal pituitary adenomectomy. Due to infiltration into the surrounding tissues, transcranial surgery was performed. However, this failed to induce a remission and thus gamma knife therapy was applied. Histopathological evaluation revealed that the glomerular lesions had progressed to a rather advanced stage of MPGN. Although this association could be coincidental, the recurrence of pituitary macroadenoma might be induced by the cessation of steroid treatment for the nephrotic syndrome.
