Incidental Finding of a Large Right Atrial Thrombus in a Patient With Cerebral Lymphoma.

Right atrial (RA) masses are rare, challenging to diagnose, and potentially life-threatening with high mortality if untreated. We present a patient presenting with diffuse large B-cell lymphoma in the brain that was incidentally found to have a large RA mass. For a better definition of the RA mass, extensive workup using multimodality imaging including chest computed tomography, transthoracic echocardiography, transesophageal echocardiography, cardiac magnetic resonance imaging, and left heart catheterization was warranted. The imaging demonstrated a large RA mass extending through the tricuspid valve into the right ventricle and superior and inferior vena cava without a mobile component. The mass was then successfully resected, and further histology examination was performed to rule out lymphoma and rare subtypes of diffuse large B-cell lymphoma. The comprehensive workup proved the RA mass to be a calcified thrombus rather than a direct metastatic spread of lymphoma.

Decompensated Non-Ischemic Cardiomyopathy Induced by Anabolic-Androgenic Steroid Abuse.

A 30-year-old male presented to the emergency department with dyspnea, fatigue, orthopnea, and paroxysmal nocturnal dyspnea for the past three months. The patient admitted to anabolic steroid use for the past 11 years. Transthoracic echocardiography was significant for severely dilated left ventricle, diffuse hypokinesis, ejection fraction < 15%, and grade II diastolic dysfunction. The patient was diagnosed with decompensated, non-ischemic cardiomyopathy stage C, and New York Heart Classification (NYHA) class III > IV, likely from use of anabolic steroids, after a negative workup for other etiologies. On follow-up after continuation of guideline-directed medical therapy, the patient demonstrated improved heart failure status (NYHA class I > II). Cardiomyopathy is a rare but important adverse effect of anabolic steroids to consider.

Tri-Valvular Endocarditis in a Previously Normal Heart Misdiagnosed as Recurrent Valley Fever.

Infective endocarditis (IE) is classified as an infection of any cardiac valve or endocardial surface. This condition is associated with high morbidity and mortality; hence, early diagnosis and rapid intervention are extremely vital. Although IE is frequently found to infect only one heart valve, rare instances have shown multi-valvular involvement. Many conditions can present similar to IE, often delaying the diagnosis of IE. Coccidioidomycosis (or Valley Fever), a fungal infection endemic in the Southwestern United States, can present with features analogous to those of IE. We present the case of a middle-aged male with no underlying structural heart disease found to have tri-valvular IE after being misdiagnosed with recurrent Valley Fever.

Probable hydrochlorothiazide-induced myopericarditis: first case reported.

Hydrochlorothiazide has never been reported as a reason for myopericarditis. An African American female, with past history of hypertension, coronary artery disease, and sulfa allergy, presented with indolent onset and retrosternal chest pain which was positional, pleuritic, and unresponsive to sublingual nitroglycerin. Her medications included hydrochlorothiazide (HCTZ) which was started three months ago for uncontrolled hypertension. Significant laboratory parameters included erythrocyte sedimentation rate (ESR) of 47 mm/hr and peak troponin of 0.26 ng/mL. Transthoracic echocardiogram (TTE) revealed preserved ejection fraction with no segmental wall motion abnormalities; however, it showed moderate pericardial effusion without tamponade physiology. We hypothesize that this myopericarditis could be due to HCTZ allergic reaction after all other common etiologies have been ruled out. There is a scarcity of the literature regarding HCTZ as an etiology for pericardial disease, with only one case reported as presumed hydrochlorothiazide-induced pericardial effusion. Management involves discontinuation of HCTZ and starting anti-inflammatory therapy.

RETRACTED: I do not even remember what I smoked! A case of marijuana-induced transient global amnesia.

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the editor as it is a duplicate of a paper that has already been published in JSciMed Central, JSM Clinical Case Reports: Mansou G, Tantoush H, Abuzaid A, Al Ashry H, Bellamkonda P. Marijuana Induced Transient Global Amnesia: JSM Clin Case Rep 2(4): 1043. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper has not been previously published and is not under consideration for publication elsewhere. A longer version of this case report was published on March 10, 2014, by J Sci Med Central, 3 months before three of the original authors submitted it to AJM. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process. Joseph S.
