Case Illustration of the Natural History of Left Dominant Arrhythmogenic Cardiomyopathy.

Arrhythmogenic left ventricular cardiomyopathy is an increasingly recognized cause of recurrent myocarditis, a mimicker of acute coronary syndrome, and an important cause of malignant ventricular arrythmias and heart failure. Desmoplakin is a protein that is critical to maintaining the structural integrity of the myocardium. Disruption of desmoplakin leads to fibrofatty infiltration of the myocardium which leads to congestive heart failure, cardiac arrhythmias, and sudden cardiac death.

Prospective comparison of echocardiography versus cardiac magnetic resonance imaging in patients with Ebstein's anomaly.

Ebstein's anomaly (EA) is primarily diagnosed by echocardiography. The purpose of this study was to compare echocardiography and magnetic resonance imaging (MRI) in EA. Data from cardiac MRI and echocardiography were prospectively collected from 16 patients with EA.

ECG-gated cardiac CT angiography using 64-MDCT for detection of patent foramen ovale.

Objective: The purpose of our study was to show the feasibility of ECG-gated, 64-MDCT cardiac angiography for the detection of patent foramen ovale (PFO).

Materials And Methods: Chart review was performed on 214 consecutive patients referred for clinically indicated 64-MDCT angiography. The study cohort consisted of 20 patients who had previously undergone transesophageal echocardiography (TEE).

Spontaneous adrenal hemorrhage during pregnancy: a review of the literature and a case report of successful conservative management.

Spontaneous adrenal hemorrhage is an acute hemorrhage of the adrenal gland that occurs in the absence of trauma or anticoagulant therapy. The incidence of this condition in pregnancy is unknown. We describe a patient with spontaneous unilateral adrenal hemorrhage that occurred during the third trimester of pregnancy.

Tumefactive cysts: a delayed complication following radiosurgery for cerebral arterial venous malformations.

We report five cases of symptomatic delayed cyst formation after radiosurgery for intracranial arterial venous malformations. Median time to discovery of the cysts following most recent radiosurgery was 59 months (range, 34-89 months). In all five patients, the radiation therapy-induced cysts exhibited tumefactive characteristics, including vasogenic edema, mass effect, and nodular enhancement.

Nonlinearity of FMRI responses in human auditory cortex.

An investigation was made into the nature of the nonlinearity observed in auditory functional magnetic resonance imaging (fMRI) experiments associated with increases in total duration of acoustic imaging noise [e.g., Edmister et al.

The lactating breast: MRI findings and literature review.

Normal physiologic changes in the breast related to pregnancy and lactation can reduce the sensitivity of imaging modalities, such as mammography. This is likely to be true for other breast imaging techniques such as magnetic resonance imaging (MRI). Although malignancy is relatively uncommon in lactating breasts, patients may develop palpable abnormalities that require imaging evaluation.

Invasive lobular carcinoma: spectrum of enhancement and morphology on magnetic resonance imaging.

Invasive lobular carcinoma (ILC) may be a difficult tumor to detect early by physical examination, mammography, or ultrasound. We undertook this study to describe the spectrum of gadolinium enhancement and morphologic features of ILC on magnetic resonance imaging (MRI). Nineteen patients with ILC who presented with a palpable mass, a mammographically visible abnormality, or an unknown primary underwent preoperative MRI of both breasts using a T1-weighted high-resolution gradient echo sequence (pre- and postcontrast), and an echoplanar sequence during the administration of gadolinium.

Occult contralateral breast carcinoma incidentally detected by breast magnetic resonance imaging.

The incidence of synchronous bilateral breast cancers has been reported to be between 3.4% and 7.4%, as detected on mammography, physical examination, or both.
