A large subchorionic hematoma in pregnancy: A case report.

INTRODUCTION

Subchorionic hematoma (SCH) is a rare type of intrauterine hematoma, usually with limited impact on fetuses and pregnant women. But massive hematoma causes significant space occupying effect, affects blood supply of the fetus and finally may lead to fetus demise.

PATIENT CONCERNS: In this case report, we reported a 22-year-old pregnant woman presented to our hospital with complaint of irregular lower abdominal pain.

DIAGNOSIS: Ultrasonography and magnetic resonance imaging confirmed an intrauterine mass with a compressed growth-restricted fetus.

INTERVENTIONS: The patient underwent diseases induced labor after confirmation of fetus demise by ultrasonography.

OUTCOMES: Histopathological examination of the mass revealed a SCH.

CONCLUSION

Though small SCH can be found in quite a few pregnant women and is usually harmless, enormous hematoma can result in adverse pregnancy outcomes. It may be difficult, in some cases, to differentiate it from uterine tumors or placental tumors by means of ultrasonography and magnetic resonance imaging, especially when the mass is hyperechoic under ultrasonography. This case report stresses the importance of regular examinations of pregnant women.
