MRI of lesser metatarsophalangeal joint plantar plate tears and associated adjacent interspace lesions.

Objective: To identify the variety of second and third intermetatarsal space (IS) lesions that may coexist with and without adjacent metatarsophalangeal joint (MTP) plantar plate (PP) tears.

Materials And Methods: One hundred forefoot MRIs in 96 patients with metatarsalgia obtained between 30 September 2011 and 21 July 2012 using 1.5- or 3-T MRI were retrospectively reviewed in consensus by two MSK radiologists and one podiatrist (DPM).

Sacral fractures after lumbosacral fusion: a characteristic fracture pattern.

Objective: The purpose of this study was to describe the radiologic pattern of sacral fractures after lumbosacral fusion and to identify clinical characteristics relevant to the radiologic diagnosis.

Materials And Methods: A search of CT, nuclear medicine, and MRI radiology reports over a 5-year period at our institution revealed a total of 23 patients with sacral fractures after lumbosacral fusion. Two radiologists reviewed all of the images to determine the sacral fracture pattern.

Radiological reasoning: miliary disease, vertebral osteomyelitis, and soft-tissue abscesses.

Objective: We present a case of disseminated coccidioidomycosis with miliary disease and extrathoracic spread to the breast, the retroperitoneum, the soft tissues of the neck, and multiple vertebrae with spinal cord compression. We discuss the differential diagnosis of the imaging presentation, as well as the specific clinical and imaging features of coccidioidomycosis.

Conclusion: Disseminated coccidioidomycosis in a nonendemic area can be difficult to diagnose, even with an excellent clinical history, as almost every organ system can be involved.

Pancreatitis in initially occult gastric heterotopic pancreas.

Heterotopic pancreas is an uncommon but important entity in the differential diagnosis of a gastric mass, as it has management and prognostic implications distinct from other gastric tumors. We present a case of heterotopic pancreas in the stomach, which was initially endoscopically occult but developed superimposed pancreatitis leading to its clinical presentation and detection as an apparently new gastric neoplasm.

Posttransplantation lymphoproliferative disorder in pediatric recipients of solid organ transplants: timing and location of disease.

Objective: The objective of our study was to correlate the location of radiologic presentation and time to onset of posttransplantation lymphoproliferative disorder (PTLD) with the allograft type received in a population of pediatric heart, lung, liver, kidney, and bone marrow transplant recipients.

Conclusion: Symptomatic PTLD in children manifests earliest in lung recipients and can involve any organ system. However, PTLD in the thorax is most common after lung transplantation, and PTLD in the abdomen most commonly follows kidney transplantation.
