Pulmonary embolism after ECT.

Electroconvulsive therapy (ECT) is a safe procedure, infrequently associated with life-threatening complications. Pulmonary embolism (PE) as a complication of ECT has been rarely reported. We describe a nonfatal case of PE that developed during ECT in a 50-year-old man with depression, hypertension, and diabetes. He developed symptoms of PE immediately upon awakening from the eighth right unilateral ECT, which was later confirmed by spiral chest computed tomography. We review the literature, discussing risk factors relevant to the pathophysiology of PE and making suggestions about the management of patients with suspicious symptoms.

Value of magnetic resonance imaging in muscle trauma.

While most muscle injuries are recognized clinically, magnetic resonance imaging (MRI) is the ideal noninvasive test to assess their extent and severity, which impacts therapy and influences prognosis. Typical examples of these injuries include muscle contusions, lacerations, sprains, and delayed onset muscle soreness. For other less common traumatic muscle conditions (exertional compartment syndrome, muscle herniation, and traumatic denervation), the clinical findings are often subtle or ambiguous and MRI will indicate the correct diagnosis. In patients with known muscle trauma, MRI can detect complications such as hematoma or seroma development, scarring and fibrosis, and myositis ossificans. This article illustrates the spectrum of muscle injuries, emphasizing the value of MRI in their diagnosis.

Focal hepatic lesions: diagnostic value of enhancement pattern approach with contrast-enhanced 3D gradient-echo MR imaging.

Focal hepatic lesions constitute a daily challenge in the clinical setting. However, noninvasive methods can be useful in the detection and characterization of these lesions. The noninvasive diagnosis of liver lesions is usually achieved with contrast material-enhanced computed tomography and magnetic resonance (MR) imaging. Dynamic three-dimensional gradient-recalled-echo MR imaging provides dynamic contrast-enhanced thin-section images with fat saturation and a high signal-to-noise ratio and is excellent for the evaluation of various focal hepatic lesions. A comprehensive MR imaging examination in this setting includes T2-weighted and chemical shift T1-weighted imaging and demonstrates characteristic enhancement patterns that can be helpful in the diagnosis of most of these lesions. These enhancement patterns are seen during particular phases of contrast-enhanced imaging and include arterial phase enhancement, delayed phase enhancement, peripheral washout, ring enhancement, nodule-within-a-nodule enhancement, true central scar, pseudocentral scar, and pseudocapsule. Familiarity with these enhancement patterns can help in the identification of specific focal lesions of the liver.
