Magnetic Resonance Imaging of Benign Cardiac Masses: A Pictorial Essay

The differential diagnosis for a cardiac mass includes primary and metastatic neoplasms. While primary cardiac tumors are rare, metastatic disease to the heart is a common finding in cancer patients. Several “tumor-like” processes can mimic a true cardiac neoplasm with accurate diagnosis critical at guiding appropriate management. We present a pictorial essay of the most common benign cardiac masses and “mass-like” lesions with an emphasis on magnetic resonance imaging features.

Abstract Background Pituitary abscess is a rare condition with nonspecific symptoms that can be delayed. Proper diagnosis needs to occur preoperatively so that the management can be set up accordingly. Accurate diagnosis is challenging because many differential diagnoses can exhibit the same magnetic resonance imaging features. Case presentation We report two cases of pituitary abscess. The first patient was a 66-year-old Arab woman who underwent a surgical procedure for a pituitary macroadenoma and presented 3 months later with chronic headaches and panhypopituitarism. A pituitary abscess was found on the follow-up magnetic resonance imaging. The second patient was a 64-year-old Arab man with no medical history who presented with a chiasmal syndrome with headaches and panhypopituitarism. Brain magnetic resonance imaging showed a heterogeneous pituitary mass that turned out to be a pituitary abscess intraoperatively. These two patients were treated with hormone substitution, endoscopic transsphenoidal drainage, and antibiotherapy, with excellent outcomes. Conclusions Pituitary abscess is a rare and serious condition. Preoperative diagnosis can be challenging because of the many existing differential diagnoses upon imaging. Magnetic resonance imaging is the mainstay technique of imaging due to its multimodal nature. These cases demonstrate the variable patterns of a pituitary abscess seen on magnetic resonance imaging and the potential difficulties in achieving an accurate diagnosis preoperatively due to many other conditions potentially exhibiting the same magnetic resonance imaging features.

And Function

Non-ischemic cardiomyopathies are defined as either primary or secondary diseases of the myocardium resulting in cardiac dysfunction. While primary cardiomyopathies are confined to the heart and can be genetic or acquired, secondary cardiomyopathies show involvement of the heart as a manifestation of an underlying systemic disease including metabolic, inflammatory, granulomatous, infectious, or autoimmune entities. Non-ischemic cardiomyopathies are currently classified as hypertrophic, dilated, restrictive, or unclassifiable, including left ventricular non-compaction. Cardiovascular Magnetic Resonance Imaging (CMRI) not only has the capability to assess cardiac morphology and function, but also the ability to detect edema, hemorrhage, fibrosis, and intramyocardial deposits, providing a valuable imaging tool in the characterization of non-ischemic cardiomyopathies. This pictorial essay shows some of the most important non-ischemic cardiomyopathies with an emphasis on magnetic resonance imaging features.

Distinguishing Features

Peripheral nerve sheath tumours (PNST) may be benign or malignant. Benign PNSTs include neurofibroma and schwannoma. Neurogenic tumours share certain characteristic imaging features, suggested by a fusiform-shaped mass with tapered ends, the “split-fat” sign, atrophy of the muscles supplied by the involved nerve, the “fascicular sign,” and the “target sign”; these imaging features are best demonstrated on magnetic resonance imaging. This pictorial essay emphasizes the characteristic signs and distinguishing features of PNSTs on imaging.

Acute Transverse Myelitis

Acute transverse myelitis is a rare and disabling disorder. Data on the imaging features in children are sparse. The aim of this study was to describe the clinical and magnetic resonance imaging findings characteristic of pediatric idiopathic acute transverse myelitis and to identify those with prognostic value. The database of a tertiary pediatric medical center was retrospectively reviewed for patients aged less than 18 years who were diagnosed in 2002-2017 with acute transverse myelitis that was not associated with recurrence of a demyelinating autoimmune event. Data were collected on clinical, laboratory, and imaging findings and outcome. A total of 23 children (11 male, 12 female) met the study criteria. Mean age at disease onset was 10 years, and mean duration of follow-up was 6 years 10 months. Spinal cord and brain magnetic resonance imaging scans were performed on admission or shortly thereafter. The most common finding was cross-sectional involvement, in 16 patients (70%). The mean number of involved spinal segments was 8. The most frequently involved region was the thoracic spine, in 17 patients (74%). Clinical factors predicting good prognosis were cerebrospinal fluid pleocytosis, absence of tetraparesis, and prolonged time to nadir. In conclusion, most children with acute transverse myelitis appear to have a good outcome. Prompt diagnosis and treatment are important. Further research is needed in a larger sample to evaluate the predictive value of imaging features.
