A 19-year-old male presenting with acute pulmonary edema and severe biventricular heart failure was diagnosed as having Becker's muscular dystrophy. This case is remarkable in that congestive heart failure had not been largely preceded by neuromuscular symptoms.
Muscle degeneration in muscular dystrophies often includes a period of edema before fatty replacement of muscle tissue. Magnetic resonance imaging (MRI) has been used successfully to characterize muscle and fat patterns in several types of muscular dystrophies. Recent MRI techniques enable
To assess the presence and persistence of muscular edema and increased myoplasmic sodium (Na(+)) concentration in Duchenne muscular dystrophy (DMD). We examined eight DMD patients (mean age 9.5 ± 5.4 years) and eight volunteers (mean age 9.5 ± 3.2 years) with 3-tesla proton ((1)H) and (23)Na
By means of magnetic resonance imaging (MRI), the proton spin-lattice relaxation times (T1 values) of the skeletal muscles were measured in Duchenne muscular dystrophy (DMD) carriers and normal controls. The bound water fraction (BWF) was calculated form the T1 values obtained, according to the fast
Congenital muscular dystrophy (CMD) comprises a heterogeneous group of muscle disorders. We report on two stillborn sibs with early lethal CMD and a prematurely born boy who died within minutes after birth. The pregnancies were complicated by polyhydramnios. All presented with arthrogryposis
We report a case of birdshot chorioretinopathy (BSCR) in a patient with facioscapulohumeral muscular dystrophy (FSHD). A 40-year-old male with history of facioscapulohumeral muscular dystrophy with significant facial diplegia and lagophthalmos presents for an evaluation of bilateral choroiditis with
The dystrophinopathies comprise a group of X-linked genetic diseases that feature dystrophin deficiency. Duchenne and Becker muscular dystrophy are characterized by progressive weakness and wasting of skeletal, smooth, and/or cardiac muscle. Duchenne muscular dystrophy (DMD) is the most severe
Mutations in LMNA, which encodes nuclear lamins A and C, cause a broad range of diseases, including autosomal dominant Emery-Dreifuss muscular dystrophy (EDMD) and related disorders with a predominant cardiomyopathy. Homozygous Lmna model "knock-in" and null mice develop cardiomyopathy, whereas
Patients with bi-allelic loss-of-function mutations in the gene ANO5 most commonly present with muscular dystrophy. In some studies, patients with ANO5-related dystrophy (ANO5-RD) had evidence of mild cardiac abnormalities; however, cardiac magnetic resonance imaging (MRI) has not been used for
METHODS
A 19-year-old man with congestive heart failure reported recent onset of exercise-induced dyspnea and pitting edema of the face. He also developed increasing muscular weakness. Three years before the diagnosis of autosomal-dominant Emery-Dreifuss muscular dystrophy (EDMD) had been
The pathomorphologic mechanism responsible for abnormal perfusion imaging during thallium-201 myocardial single photon emission computed tomography (201Tl-SPECT) in patients with Duchenne's progressive muscular dystrophy (DMD) was investigated. Hearts from 7 patients with DMD were evaluated

Cardiac dysfunction is a leading cause of morbidity and mortality in Duchenne muscular dystrophy (DMD). This case highlights the importance of steroids in treating cardiac complications of DMD and the dangers of discontinuing or switching between steroid classes.

OBJECTIVE
In boys with Duchenne muscular dystrophy (DMD), (1)H MRI suggested muscular edema before fatty degeneration. Using specific (23)Na MRI sequences, we tested the hypothesis that the edema is caused by an osmotic effect due to increased myoplasmic Na(+) content rather than inflammation that
Objective: To analyze the clinical and magnetic resonance imaging (MRI) features of congenital muscular dystrophy (CMD) to improve the diagnostic level. Method: Clinical manifestations and thigh muscle MRI results of 8 cases of CMD diagnosed on genetic level from April 2013 to November 2015 were
