An eleven-year-old male gymnast felt right wrist pain when performing handstands on the floor without any major traumas. Displaced scaphoid fracture was observed on the anteroposterior view of the radiograph. Both on the T1-weighted image from magnetic resonance imaging (MRI) and on the short TI inversion recovery (STIR) image from MRI, low intensity was detected at the middle of the ossification center of the scaphoid and the physis and the articular cartilage covering the scaphoid bone were preserved without any injury. The patient was diagnosed with stress fracture of the ossification center of the scaphoid and successfully treated conservatively.

Female Distance Runner

Stress fractures are a frequent cause of lower extremity pain in athletes, and especially in runners. Plain imaging has a low sensitivity. Magnetic resonance imaging (MRI) or bone scan scintigraphy is the criterion standard, but expensive. We present the case of a young female distance runner with left shin pain. Plain radiography was unremarkable. Ultrasound showed focal hyperechoic elevation of the periosteum with irregularity over the distal tibia and increased flow on Doppler. These findings were consistent with a distal tibia stress fracture and confirmed by MRI. Examination of our case will highlight the utility of considering an ultrasound for diagnosis of tibial stress fracture.

Tentative Diagnosis

We report a rare case of myxofibrosarcoma arising in the neck. A 55-year-old man presented with a two-year history of left-sided, painless, submandibular swelling. Computed tomography and magnetic resonance imaging (MRI) revealed an 80 × 35 mm, well defined, lobulated, submandibular tumour extending to the parapharyngeal space. The tumour showed uniformly low intensity and marked hyperintensity in T1- and T2-weighted MRI scans, respectively, and was scarcely enhanced by gadolinium. A tentative diagnosis of lymphangioma or plunging ranula was made, and the patient underwent local injection of OK-432, which proved to be ineffective. Resection of the tumour was then performed via a transcervical approach. The tumour was histopathologically and immunohistochemically diagnosed as a low-grade myxofibrosarcoma. The patient's post-operative clinical course was uneventful, and the patient was free of disease 27 months after surgery. The pathology, clinical characteristics and treatment of myxofibrosarcoma are bibliographically reviewed.

Background Suspected scaphoid fracture (SF) after a fall on an outstretched hand is a common presentation in the emergency department. Magnetic resonance imaging (MRI) or computed tomography (CT) has been suggested to assist in the diagnosis or exclusion of SF. Purpose To compare MRI and CT at diagnosing occult SFs. Material and Methods We routinely perform CT scans in patients with clinically suspected occult SF, after 7–10 days of injury following two negative radiographs. All eligible patients with a clinically suspected SF, but negative radiographs and a negative CT, underwent an MRI scan to assess further for evidence of occult fracture. Results A total of 100 patients were included in our study. MRI showed fractures in 16% of the time (in 15 patients) when plain radiographs and CT did not. Of these fractures, 8% were SFs. In addition to fractures, 10% had bone bruising. A total of 25% of patients with fractures and bone bruising were referred to the hand surgery team for further follow-up. Conclusion The study demonstrated that MRI would identify a radiographically occult SF more often than CT. This supports NICE guidelines which recommend MRI as the best early diagnostic tool for occult SFs.

We report a 45-year-old male archer with stress fracture in his left ulna on the background of adult type of hypophosphatasia. The patient presented to several medical centers for pain around the left elbow and received medical treatment upon diagnosis of tenosynovitis. History of the patient revealed that he had had diagnosis of hypophosphatasia ten years ago and underwent percutaneous screwing for stress fracture on both of his femoral necks. Upon finding nondisplaced stress fracture on proximal metaphysis of the ulna on X-ray, the patient underwent magnetic resonance imaging (MRI) in order to exclude pathological causes. No additional pathology was observed in MRI scanning. The patient’s sportive activities were restricted for 6 weeks and he received conservative management with arm slings. Adult type of hypophosphatasia is a disease manifesting with widespread osteoporosis and presenting with low serum level of alkali phosphatase (ALP). Stress fracture should definitely be considered in the patients with history of hypophosphatasia and refractory extremity pain.

AbstractWhen it comes to examining the brachial plexus, ultrasound (US) and magnetic resonance imaging (MRI) are complementary investigations. US is well placed for screening most extraforaminal pathologies, whereas MRI is more sensitive and accurate for specific clinical indications. For example, MRI is probably the preferred technique for assessment of trauma because it enables a thorough evaluation of both the intraspinal and extraspinal elements, although US can depict extraforaminal neural injury with a high level of accuracy. Conversely, US is probably the preferred technique for examination of neurologic amyotrophy because a more extensive involvement beyond the brachial plexus is the norm, although MRI is more sensitive than US for evaluating muscle denervation associated with this entity. With this synergy in mind, this review highlights the tips for examining the brachial plexus with US and MRI.
