Posterior dislocation of the sternoclavicular joint is a rare injury. It can be associated with life-threatening complications. Computed tomography is the imaging modality of choice with which possible associated injuries can be detected. Acute injuries are managed with closed reduction under general anaesthesia. A fracture-dislocation is inherently more(More)
Although case reports have always had a place at the foundation of medical knowledge, established radiology journals have increasingly focused their efforts on major research studies. This de-emphasis of case reports has resulted in a dearth of opportunities to publish them. Case reports continue to mark the frontiers of what we know as physicians, and have(More)
We report a case of a 50-year-old man with extensive metallosis 20 years after right total hip arthroplasty. CT demonstrated osteolysis and radiodense debris surrounding the right hip joint. Although the radiographic appearance of metallosis has been well documented in the literature, the CT appearance of metallosis after total hip arthroplasty has been(More)
Over the past few years, several studies have demonstrated favorable clinical outcomes and low complication rates using the ankle Tightrope® syndesmosis fixation system. The traditional surgical procedure of screw fixation for syndesmosis injury is associated with high complication rates of loosening, screw fracture, nonanatomic fixation, and postoperative(More)
Mycetoma, also known as Madura foot, is a rare soft-tissue granulomatous infection caused by Actinomyces or true fungi. The MRI "dot-in-circle" sign has been described as a characteristic finding of mycetoma. This sign represents spherical T2 bright masses containing central and intervening low-signal-intensity foci. However, other soft-tissue masses can(More)
We present a case of an abdominal cavity myolipoma which herniated through a low transverse abdominal (Pfannenstiel) incision, and presented as an enlarging abdominal wall mass. Magnetic resonance imaging (MRI) prior to surgery demonstrated an encapsulated solid tumor mass demonstrating fat signal and and increased T2-weighted signal. Postsurgical(More)
HTLV-1-associated myelopathy (HAM), also known as tropical spastic paraparesis (TSP), is a chronic progressive demyelinating disease that affects the spinal cord and white matter of the central nervous system. The lifetime incidence of HAM in HTLV-1 carriers is estimated to be less than 5%. Typical time of onset is in the fourth decade of life, with a(More)
Injuries of the anterior cruciate ligament are commonly encountered in clinical practice, and occur in a wide variety of settings, from sports-related injuries to polytrauma. Tears of the anterior cruciate ligament supersede osseous avulsion in the adult demographic; however, in the pediatric population, osseous avulsion reflects the most frequent injury.(More)
Migrating orthopedic hardware has widely been reported in the literature. Most reported cases of migrating hardware involve smooth Kirschner wires or loosening/fracture of hardware involved with joint stabilization/fixation. It is unusual for hardware to migrate within the soft tissues. In some cases, smooth Kirschner wires have migrated within the thoracic(More)
We present a case of Kashin-Beck Disease primarily affecting the ankles. Our findings are consistent with other reports of the symptoms, incidence, and progression of these diseases. At this time, our patient has chosen conservative treatment, but is considering eventual osteoarticular allografts. According to the available literature, surgical treatment is(More)
