Catamenial hemothorax: a perplexing tale of unilateral hemothorax

Parvathy Priya Yoganadhan et al. Indian J Thorac Cardiovasc Surg. 2025 Mar.

Abstract

The clinical entity in which functional endometrial tissue is present in the thoracic cavity causing various clinical manifestations is called thoracic endometriosis syndrome (TES). Catamenial hemothorax (CHt) is a clinical manifestation of TES characterized by recurrent hemothorax which occurs during each menstrual cycle. The establishment of a correlation between menstrual cycle and clinical features is necessary for the diagnosis. We report a case of CHt in a 36-year-old female who presented with recurrent right-side pleural effusion.

Keywords: Catamenial hemothorax; Thoracic endometriosis syndrome.
