We describe a case in which an elderly woman sustained a manubrial fracture after a fall from standing. The patient did not sustain further complications from her injury and was managed medically. The radiographic appearance and clinical implications of this event are discussed.

T he radiographic presentation of air within the mediastinal planes is usually an indication of serious breach of an intrathoracic luminal structure. The unprovoked appearance of pneumomediastinum demands exclusion of such serious pathology before a course of conservative management can be safely pursued. A case of spontaneous pneumomediastinum in a patient with a history of asthma in childhood...

Cyst formation is an uncommon pathologic finding in heterotopic pancreas. It is sometimes reported in a duodenal location but very rarely in a gastric location and leads to very large lesions of unusual endoscopic and radiographic appearance. Two cases of gastric heterotopic pancreas are described in which cystic zones in the gastric wall were found at preoperative ultrasound or computed tomogr...

A solitary pulmonary nodule (SPN) is the most common radiographic presentation of lung cancer. The imaging characteristics of solitary pulmonary nodules are described and illustrated. The appearance and implications of extension of lung cancer to the pleura are explored. Finally, the contribution of various thoracic imaging modalities to the diagnosis and staging of lung cancer are discussed br...

Osteoblastoma is a rare bone tumor that usually affects the vertebrae. We present the first known case of osteoblastoma arising in the hyoid bone, in a patient who presented with a neck mass and dysphagia. The radiographic appearance of the tumor is similar to that of low-grade chondrosarcoma, with well-defined expansion of the bone and central chondroid matrix.

Epidermoid and dermoid cysts of the jaws are seen rarely. The formation theories of the intraosseous epidermoid cyst (IEC) are not clear. The radiographic appearance is similar with unilocular cysts. Surgical enucleation is the suggested treatment method for epidermoid cysts. This case report presents bilateral mandibular intraosseous epidermoid cysts with impacted wisdom teeth which is the fir...

Cavernous hemangiomas involving the dura are relatively uncommon lesions . We report a case of a cavernous hemangioma with features of sinus pericranii with venous lakes that involved the dura as well as calvarium. Associated with it were radiologic bone changes atypical for hemangioma. In presenting our case, we correlate the computed tomographic (CT) appearance with surgical and conventional ...

In a rare case of common atrioventricular canal mimicking tricuspid atresia the clinical, radiographic, electrocardiographic, and M mode echocardiographic features were indistinguishable from those of classic tricuspid atresia. The cross sectional echocardiographic appearance and right atrial cineangiographic features were distinctive, however, and can be used to discriminate between this anoma...

We present a case of a solitary neurofibroma involving the right posterior shoulder of a 69-year-old man with degeneration into a massive, malignant peripheral nerve sheath tumor measuring more than 3 times the average reported size. The radiographic, magnetic resonance imaging, and computed tomographic features are compared with the gross appearance and pathology.

In the neutropenic host, the impaired inflammatory response diminishes the signs and symptoms of pulmonary infection, making diagnosis difficult. A practical approach to diagnosis and treatment in this population is to assess the radiographic appearance of infiltrates as localized (occurring as early, refractory or late phase), or diffuse; this approach is reviewed here.
