Ileoileal Intussusception in a 1-Year-Old Boy: Ultrasound Findings, Bowel Ischemia, and Meckel Diverticulum as a Lead Point

Edited by ScholarGen MediAI Team Executive Answer Ileocolic intussusception is an uncommon form of pediatric intussusception in which one segment of ileum telescopes into an adjacent segment of ileum. In this 1-year-old boy, persistent vomiting despite treatment prompted abdominal radiography followed by ultrasound. The radiographs showed dilated small-bowel loops and multiple air-fluid levels with little gas in the lower abdomen, suggesting small-bowel obstruction. Ultrasound demonstrated the characteristic layered appearance of small-bowel intussusception, including a pseudokidney appearance on longitudinal imaging. Color Doppler showed partially preserved wall vessels but absent detectable flow in portions of the involved bowel, raising concern for ischemia. Surgery confirmed irreducible ileoileal intussusception with bowel ischemia, requiring resection. Pathology identified a Meckel diverticulum, which was considered the pathologic lead point. Why This Case Matters Intussusception ...

Hypoplastic Left Heart Syndrome in an Adult: CT Findings After Fontan Palliation

  A radiologist-focused review of HLHS, Fontan anatomy, absent IVC with azygos continuation, and Fontan-associated liver disease. A 25-Year-Old Man With Persistent Chest Pain Edited by ScholarGen MediAI Team Executive Answer A 25-year-old man presented with persistent chest pain, and contrast-enhanced cardiac CT demonstrated the characteristic anatomy of hypoplastic left heart syndrome (HLHS) after Fontan palliation. The key findings include a severely underdeveloped left-sided cardiac system, mitral stenosis, a lateral-tunnel Fontan pathway, a widely patent atrial septal communication, and marked right ventricular enlargement. The CT also  shows a prominent systemic venous anomaly consistent with  an absent  inferior vena cava (IVC) with azygos continuation . An additional upper-abdominal image shows an irregular hepatic contour consistent with cirrhosis, illustrating an important long-term complication of Fontan physiology. Why This Case Matters Hypoplastic left h...

Chronic Heel Pain? Intraosseous Lipoma of the Calcaneus on X-Ray and MRI

-
Image
  Edited by ScholarGen MediAI Team Chronic Heel Pain Is Not Always Plantar Fasciitis Chronic heel pain is one of the most common complaints encountered in orthopedic, podiatric, sports medicine, and musculoskeletal radiology practice. Plantar fasciitis, Achilles tendinopathy, calcaneal stress fracture, and degenerative disorders are usually considered first. However, when heel pain persists despite appropriate conservative treatment, imaging should prompt clinicians to look beyond soft-tissue disorders and evaluate the bone itself. One uncommon but important diagnosis is intraosseous lipoma , particularly calcaneal intraosseous lipoma . An intraosseous lipoma is a rare benign bone lesion composed predominantly of mature adipose tissue within the medullary cavity. Although uncommon, the calcaneus is one of its characteristic locations. The lesion may be completely asymptomatic and discovered incidentally, or it may present with chronic, activity-related heel pain. Its importance lie...
