Epiphyseal separation of the distal femur is a rare entity. It usually occurs as a complication of a traumatic vaginal or cesarean delivery, particularly in breech position. It is considered a Salter-Harris type 1 fracture, where the epiphysis separates from the metaphysis resulting in physeal widening and frequently displacement of the epiphysis in relationship to the metaphysis. Only a few cases are reported in the literature. We report a case of distal epiphyseal separation of the distal femur in a 5-day-old patient who presented to the emergency department with swollen right foot. He was born at term in breech presentation via C-section delivery. At the presentation the physical examination revealed edema from the thigh to foot, decreased range of movement of the right hip, and he cried with palpation of the right tight. Lateral radiographs of the right lower limb showed metaphyseal irregularity involving the distal femur simulating a corner fracture, and posterior displacement of the distal femoral epiphysis relative to the metaphysis. Subsequent ultrasound of the right knee demonstrated posterior displacement of the distal femoral epiphysis with a 5 mm gap and significant soft tissue swelling, confirming epiphyseal separation of the distal femoral epiphysis. As the distal femoral epiphyseal secondary ossification center appears at approximately 38th week of gestational age, the radiograph is commonly the first imaging method to depict distal femoral epiphyseal separation. However, the radiographic diagnosis is challenging, and it can mimic a corner fracture leading to the suspicion of non-accidental injury. Therefore, ultrasound is an excellent complementary tool given its lack of radiation, no need for sedation, short examination time and high ability to assess the musculoskeletal structures with direct evaluation of the surface of osseous elements, cartilage and soft-tissue structures. Although this condition is uncommon, awareness of its imaging features among pediatric radiologists is crucial to avoid misdiagnosis and unnecessary additional imaging. Read More

Over the past decades, pediatric nutritional disorders have undergone profound shifts in prevalence and clinical presentation. Whereas in some places of the globe malnutrition rates have increased significantly due to poverty expansion, in other places childhood obesity has surged, now affecting a substantial portion of school-aged children. In developed nations, obesity rates are even higher, whereas in developing regions, malnutrition remains a pressing concern. Chronic illnesses, prolonged hospitalizations, and neuropsychiatric conditions are contributors to nutritional deficits. Although radiologic findings have been well documented for some hypovitaminosis, other conditions such as anorexia nervosa and autism have been described in isolated imaging reports. On the other hand, pediatric obesity presents with musculoskeletal (MSK) manifestations and nonspecific pain syndromes that require further scrutiny. In this case presentation we provide an overview of the spectrum of imaging findings associated with pediatric nutritional disorders, whether caused by deficiency or excess. CONTENT ORGANIZATION: 1) Overview and epidemiology of pediatric nutritional disorders that lead to (a) MSK tissue deficiency including different hypovitaminosis, congenital, metabolic and neuromuscular disorders, bone deficiencies, conditions that manifest with gelatinous bone marrow transformation or soft tissue paucity, or (b) MSK tissue excess including genetic and metabolic disorders that manifest with fat overgrowth and hypertrophy syndromes. 2) Imaging findings of MSK bone and soft tissue deficiency or excess by different modalities (conventional radiology, ultrasound, CT, MRI). 3) Pearls, pitfalls and associated clinical findings specific for the described conditions. 4) Review of follow-up imaging considerations. 5) Discussion of the radiologist’s role in managing a child/adolescent with nutritional disorders. SUMMARY: Major teaching points of this case presentation include: 1) Understanding different clinical presentations and key imaging findings that lead to the diagnosis of disorders that manifest with MSK deficiency or excess. 2) Differentiating disorders of either part of the spectrum (deficiency or excess) as an essential component for patients to receive appropriate care in a timely manner. 3) Providing recommendations for imaging follow-up as part of the integrated clinical-laboratory-imaging care of patients with nutritional disorders.
