Hydrops of a fetus of unknown etiology with the development of severe intracranial hemorrhage.

Prenatally diagnosed intracranial hemorrhage in the fetus is associated with a wide range of neonatal disorders, from completely uncomplicated physiological development to severe neurological impairment or death. The incidence is 0.6-1/1,000 births. Intracranial hemorrhage, depending on the anatomical location, is classified as intraventricular, intracerebral, cerebral, subarachnoid, and subdural. In this case report, we describe a rare case of spontaneous intracranial hemorrhage in a fetus monitored for hydrops and pregnancy complicated by polyhydramnios. A literature research was carried out. In the discussion, we present the diagnostic algorithm and the results of the examinations performed. To complete the case report, we add information about the management of childbirth and early death of the newborn.
