Kaposiform hemangioendotheliomas (KHE) are rare, locally aggressive vascular neoplasms. KHE most commonly arise from the extremities and less frequently the trunk and head and neck regions. Kasabach-Merritt phenomenon complicates 70% of cases. Three cases of KHE underwent prenatal evaluation and postnatal management at our center. We report the imaging findings that may allow for improved prenatal diagnosis. Case 1: 31-year-old G4P2 evaluated for cervicofacial mass at 24 weeks 5 days. Fetal ultrasound demonstrated a large, infiltrative, predominately solid, mildly heterogeneous mass with a volume of 62 mL. No calcifications or lesion hypervascularity were present. Same day MRI confirmed an infiltrative, predominately solid mass with mild heterogenous T2 signal and no internal flow voids. Repeat MRI at 34 weeks 5 days revealed increased lesion heterogeneity and internal flow voids. US at 36 weeks 3 days demonstrated a volume of 525 mL and lesion hypervascularity. Delivery was at 36 weeks 5 days by EXIT procedure. Kasabach-Merritt phenomenon developed, and postnatal biopsy was consistent with KHE. Case 2: 35-year-old G2P1 evaluated for cervical mass at 40 weeks 4 days. Fetal ultrasound demonstrated a large, infiltrative predominately solid, mildly heterogeneous mass with a volume of 180 mL. Calcifications and hypervascularity were present. Fetal MRI was not performed. Delivery the next day was by cesarean section. Kasabach-Merritt phenomenon developed. Postnatal biopsy was consistent with KHE. Case 3: 30-year-old G1P0 evaluated for cervical mass at 38 weeks 1 day. Fetal ultrasound demonstrated a large, predominately solid, heterogeneous mass with a volume of 242 mL. Calcifications and hypervascularity were present. Same day fetal MRI confirmed an infiltrative, predominately solid mass with heterogeneous T2 signal and internal flow voids. Delivery was at 38 weeks 3 days by cesarean section. Kasabach-Merritt phenomenon developed, and postnatal MRI and clinical findings were consistent with KHE. Read More

Postmortem imaging is increasingly used following stillbirths and neonatal death. Estimating time of death has legal, biological, and ethical implications. This study aims to investigate feasibility of prenatal MRI in estimating time of death in intra-uterine fetal demise (IUFD). Read More
