A case report on 111In chloride bone marrow scintigraphy in management of adrenal myelolipoma.

Medicine (Baltimore) 2019 Feb;98(8):e14625

Pathology, The Cancer Institute Hospital of the Japanese Foundation for Cancer Research.

Rationale: Adrenal myelolipoma is a benign hormone-inactive tumor composed of hematopoietic tissue and mature adipose tissue. Because this tumor tends to be rich in fat, in many cases it can be diagnosed based on computed tomography (CT) or magnetic resonance imaging (MRI) findings alone. However, in the presence of much necrosis, calcification and hematopoietic tissue and/or the absence of much fat, and in cases with tumor apoplexy, this tumor becomes difficult to differentiate from other tumors.

Cardiac Dedifferentiated Liposarcoma Requiring a Mitral Valve Replacement Complicated by Severe Paravalvular Leak: A Rare Case Report with Literature Review.

Case Rep Cardiol 2018 4;2018:2506368. Epub 2018 Sep 4.

Internal Medicine Department, Beaumont Hospital, Royal Oak, MI, USA.

Cardiac sarcomas have a high infiltrative and metastatic potential and are often associated with poor prognosis. These tumors are often identified incidentally by thoracic and cardiac imaging. However, when symptomatic, their presentation can differ based on the localized structural effects on the endocardium, myocardium, pericardium, and valves as well as on dynamic effects on the cardiac function.

PET in the Diagnostic Management of Soft Tissue Sarcomas of Musculoskeletal Origin.

PET Clin 2018 Oct;13(4):609-621

Keck School of Medicine, University of Southern California (USC), 1520 San Pablo Street, Suite L1600, Los Angeles, CA 90033.

Soft tissue sarcomas (STSs) account for less than 1% of adult solid tumors and about 7% of pediatric malignancies, causing 2% of cancer-related deaths. With the advent of PET-computed tomography (CT), the value of (18) fluorine-2-fluoro-2-deoxy-d-glucose (FDG) PET imaging to improve the management of STSs has been explored. FDG PET imaging has been found useful in restaging and treatment response assessment. Read More

Incidental Detection of Tracer Avidity in Liposarcoma on 68Ga-Labeled Prostate-Specific Membrane Antigen PET/CT.

Clin Nucl Med 2018 Sep;43(9):e334-e335

Urology, Postgraduate Institute of Medical Education and Research, India.

Ga-labeled prostate-specific membrane antigen (PSMA) PET/CT is emerging as new reference standard for imaging of prostate cancer because of superb diagnostic performance in disease staging and recurrence detection. However, a number of isolated reports have been published recently regarding the nonspecific uptake of Ga-PSMA in nonprostatic benign or malignant pathologies. We describe the case of a 76-year-old man who underwent Ga-labeled PSMA PET/CT for suspicion of prostate cancer. Read More

Among the fibers: A multimodality imaging review of intramuscular mass lesions.

Indian J Radiol Imaging 2018 Apr-Jun;28(2):214-224

Department of Radiodiagnosis and Imaging, St. John's Medical College Hospital, Bengaluru, Karnataka, India.

The common presentations of patient complaints regarding the musculoskeletal system, such as pain, swelling, and restriction of movement, lead to the imaging discovery of various lesions often located in, or arising from, skeletal muscle in the region of interest. Knowledge of the patients' clinical history, laboratory parameters, and various imaging characteristics of the implicated lesions would assist the radiologist in coming to a timely, reasonably accurate conclusion about the etiology of the patient's complaints, the severity of disease, and in directing patient therapy.
