To describe the MR characteristics that can distinguish idiopathic transverse myelitis from other intramedullary lesions. ⋯ MR findings are helpful in detecting transverse myelitis and in differentiating this entity from multiple sclerosis and cord tumors, but clinical assessment and observation of MR changes over time are essential in making the diagnosis.

Case ReportsPosttraumatic epistaxis from injury to the pterygovaginal artery.
Facial and skull base trauma can cause clinically significant epistaxis. Optimal evaluation and treatment require knowledge of the pertinent vascular and skull base anatomy. We describe a patient with extensive skull base injury and epistaxis in whom CT revealed a fracture through the roof of the nasopharynx and arteriography showed injury to the pterygovaginal (pharyngeal) artery. The fracture was successfully treated with transarterial particulate embolization.

Digital subtraction rotational angiography for aneurysms of the intracranial anterior circulation: injection method and optimization.
To optimize parameters of rotational angiography for examination of the internal carotid circulation; to compare rotational angiography with standard digital subtraction angiography (DSA) in the evaluation of aneurysms of the intracranial internal carotid circulation; and to determine tolerance and safety limits of prolonged internal carotid injection angiography. ⋯ Rotational angiography provided better definition of the aneurysmal neck and greater clarity of aneurysms than did DSA; it also improved the level of confidence in predicting the presence or absence of aneurysms, especially in the anterior communicating artery; however, in our small series it did not significantly increase the detection of aneurysms. Prolonged injection angiography was well tolerated in all patients.

Preliminary evaluation of fluid-attenuated inversion-recovery MR in the diagnosis of intracranial tumors.
To report our preliminary results in the application of a turbo fluid-attenuated inversion-recovery (FLAIR) MR technique to the diagnosis of intracranial tumors and to assess the clinical usefulness of this technique. ⋯ Turbo FLAIR images can supplement conventional spin-echo images in the diagnosis of intracranial tumors.
