Diaphragmatic Endometriosis With Contiguous Lung and Liver Involvement

Year: 2026

Type: article

Abstract: Diaphragmatic endometriosis is a rare extrapelvic condition that rarely affects adjacent organs. We report the case of a woman with a right diaphragmatic mass that exhibited a cyclic growth pattern: it regressed after menopause, regrew thereafter, remained radiologically stable during 2 years of dienogest therapy, and increased in size after treatment discontinuation. Computed tomography showed a 65-mm transdiaphragmatic mass involving the adjacent lung and liver tissues. As malignancy could not be excluded, combined thoracoscopic and laparoscopic en bloc resection was performed. Histopathology confirmed diaphragmatic endometriosis with contiguous lung and liver involvement. The patient remained recurrence-free for 2 years postoperatively.
