Gastrointestinal involvement usually presents as abdominal pain. The presence of ascites is rare with only few cases reported in the literature. We report a case of HAE with ovarian edema, ascites and elevation of CA-125 which led to an initial suspicion of ovarian neoplasia. It is important for gynaecologists to be aware of HAE, as this disease can present a symptomatology similar to that described in gynaecological diseases and therefore lead to unnecessary invasive procedures and delay proper treatment.enHereditary angioedemaC1-inhibitorAbdominal painAscitesOvarian edemaOvarian neoplasiaC1 inhibitorDiagnosisSymptomsA rare form of hereditary angioedema could be confused with ovarian cancerresearch articleopen access10.31083/j.ejgo.2021.02.2164https://doi.org/10.31083/j.ejgo.2021.02.2164645217800026
