Massive ovarian edema (MOE) is a rare benign condition that affects childbearing women including girls. MOE is thought to result from intermittent or partial torsion of the ovary compromising the venous and lymphatic drainage but with preserved arterial supply. The clinical features of MOE are nonspecific and can simulate tumors, frequently resulting in oopherectomy. Fertility-sparing surgery may be undertaken if the diagnosis is considered prospectively and intraoperatively with a wedge biopsy, avoiding unnecessary resection of the affected ovary. We present clinical presentations and imaging features that should alert pediatric radiologists to the diagnosis of MOE. Read More

Dysplasia epiphysialis hemimelica (DEH), also known as Trevor’s disease, is a rare developmental bone disease which typically involves the epiphyseal cartilage of the lower extremities. The disease is characterized by abnormal overgrowth which may lead to progressive limb deformity and gait dysfunction. Imaging is crucial in the diagnosis and the appearance maybe confused with other musculoskeletal dysplasias. This exhibit will review the pathogenesis of DEH and highlight the characteristic imaging features using multiple modalities. Read More

Lipoblastoma is a benign, rare pediatric mesenchymal tumor that develops in a myriad of anatomic locations. The imaging appearance of lipoblastoma sometimes overlaps with other tumors. Familiarity with lipoblastoma and a knowledge of benign and malignant tumors with similar imaging features will benefit practicing Radiologists, Pediatricians, and Surgeons. Our exhibit aims to expand awareness of lipoblastoma by providing a comprehensive pictorial review of cases showcasing representative MRI, CT, sonographic, and radiographic images. Suggestive imaging features of lipoblastoma that distinguish them from other fat-containing lesions will be highlighted and an emphasis on the discussion of lipoblastoma within the spectrum of pediatric lipomatous lesions will be detailed.

Evaluating the alignment and blood flow in the femoral head in patients with congenital hip dysplasia following reduction is essential to the treatment of dysplastic hips. Current practice involves an immediate postoperative contrast enhanced MRI of the casted child to identify hips that may be at risk for avascular necrosis. Contrast enhanced ultrasound (CEUS) is an emerging imaging modality that is feasible to evaluate the perfusion of the cartilaginous proximal femoral epiphysis intraoperatively, after hip reduction and prior to spica casting. This educational exhibit describes the procedure of intraoperative CEUS of the hip from the sonographers’ perspective. Read More
