Abstract: Pneumothorax can be spontaneous or secondary to a pre-existing disorder or trauma. Pneumothorax
associated with pneumoperitoneum without thoraco-abdominal communication is a rare event poorly
described in the literature. We report the case of a 73-year-old patient undergoing abdominal debulking
surgery for advanced stage ovarian cancer complicated by a pneumoperitoneum and a right-sided
pneumothorax without hernia or evidence of diaphragmatic trauma. Several physio-pathological hypotheses
have been suggested, including a potential COVID-19 infection without clear etiology. Our case report
emphasizes the possible association of pneumothorax with pneumoperitoneum related to a colon perforation
without visible diaphragmatic or mediastinal defects.
