An unusual case report of trepopnea in a patient with unilateral diaphragmatic palsy

Abstract

Trepopnea, a rare form of dyspnoea observed in lateral decubitus position is a crucial clue towards diagnosis. It indicates either cardiac or respiratory pathology that may warrant immediate attention. Usually, it has been reported the patient with congestive cardiac failure or diseased left lung who prefers the right lateral decubitus position. Only in a few cases with the unilateral lung disease it has been described. We present one such case report of trepopnea in a patient recovering from pneumonia was observed having trepopnea, which was later confirmed due to unilateral diaphragmatic palsy.
