Capitate and hamate fracture in a child: the value of MRI imaging

Carpal bone fractures in children are rare, and little is known about the appropriate tools to diagnose them, particularly in toddlers. We present a 2-year-old child with a capitate and hamate fracture. Based on our experiences with this case and on a review of the literature, we discuss the value of magnetic resonance imaging in carpal trauma in children

Ovarian germ cell tumors with rhabdomyosarcomatous components and later development of growing teratoma syndrome: a case report

<p>Abstract</p> <p>Introduction</p> <p>Development of a sarcomatous component in a germ cell tumor is an uncommon phenomenon. Most cases reported have a grim prognosis. Growing teratoma syndrome is also an uncommon phenomenon and occurs in approximately 2% to 7% of non seminomatous germ cell tumors and should be treated surgically.</p> <p>Case presentation</p> <p>We report the case of a 12-year-old Asian girl with an ovarian mixed germ cell tumor containing a rhabdomyosarcomatous component. She was treated with a germ cell tumor chemotherapy regimen and rhabdomyosarcoma-specific chemotherapy. Towards the end of her treatment, she developed a retroperitoneal mass that was increasing in size. It was completely resected, revealing a mature teratoma, consistent with growing teratoma syndrome. She is still in complete remission approximately three years after presentation.</p> <p>Conclusion</p> <p>The presence of rhabdomyosarcoma in a germ cell tumor should be treated by a combined chemotherapy regimen (for germ cell tumor and rhabdomyosarcoma). In addition, development of a mass during or after therapy with normal serum markers should raise the possibility of growing teratoma syndrome that should be treated surgically.</p

Pediatric imaging: Current and emerging techniques

Imaging has always been an important component of the clinical evaluation of pediatric patients. Rapid technological advances in imaging are making noninvasive evaluation of a wide range of pediatric diseases possible. Ultrasound and magnetic resonance imaging (MRI) are two imaging modalities that do not involve ionizing radiation and are preferred imaging modalities in the pediatric population. Computed tomography (CT) remains the imaging modality with the highest increase in utilization in children due to its widespread availability and rapid image acquisition. Emerging imaging applications to be discussed include MR urography, voiding urosonography with use of ultrasound contrast agents, CT dose reduction techniques, MR enterography for inflammatory bowel disease, and MR cine airway imaging

Fractures of the hands and feet in child abuse: imaging and pathologic features

PURPOSE: To determine the imaging and histopathologic appearance of fractures of the hands and feet in abused infants. MATERIALS AND METHODS: The imaging findings in 11 abused infants with fractures of the hands and feet were examined retrospectively. All 11 infants underwent skeletal surveys; five infants also underwent nuclear bone scanning. Postmortem radiographs of the specimen and histopathologic data were available in two infants. RESULTS: A total of 22 fractures were noted. Six infants had fractures of the hands: six metacarpal and nine proximal phalangeal fractures. Five infants had fractures of the feet: six metatarsal fractures and one proximal phalangeal fracture. Torus fractures predominated, and these patterns were confirmed at the histologic examinations. These morphologic features were consistent with a mechanism of forced hyperextension. Oblique views of the hands and follow-up skeletal surveys aided in detection of these injuries. Four of six metatarsal fractures involved the first ray. Seven patients had three or more additional fractures that involved the long bones of the upper and lower extremities, and seven patients had additional fractures of the ipsilateral extremity. CONCLUSION: Fractures of the hands and feet are subtle but important injuries in abused infants. Well-collimated, high-detail radiographs of the hands and feet should be included in the skeletal survey performed for suspected child abuse
