Pleuroparenchymal fibroelastosis (PPFE) is a rare condition currently described as an upper lobe subpleural and interstitial proliferation of predominantly elastic fibers. The etiology is unknown, and no specific diagnostic criteria have been reported. Here we report 5 cases of PPFE, 1 man and 4 women, 3 of them diagnosed at the time autopsy, 1 diagnosed in(More)
RATIONALE AND OBJECTIVES The purpose of this study was to illustrate the imaging findings on high-resolution 3T magnetic resonance neurography (MRN) in patients with suprascapular nerve (SSN) neuropathy. MATERIALS AND METHODS From 3T MRN examinations performed for brachial plexus evaluation in 51 patients over a 3-year period, 15 patients with final(More)
We describe interesting imaging features on a FDG-PET scan in a patient with bony metastases from a rare tumor. The lesions were obscured by intense bone marrow activity after the administration of hematopoietic factor at the time of diagnosis. Correlative MRI, CT scan, and pathology findings have also been illustrated. Follow-up FDG-PET scan demonstrated(More)
Heterozygous mutations in four telomere-related genes have been linked to pulmonary fibrosis, but little is known about similarities or differences of affected individuals.115 patients with mutations in telomerase reverse transcriptase (TERT) (n=75), telomerase RNA component (TERC) (n=7), regulator of telomere elongation helicase 1 (RTEL1) (n=14) and(More)
Primary sphenoid melanoma is a rare tumor. A 75-year-old man presented with complaints of headache and visual complaints for a few days. CT and MRI of the brain demonstrated a sphenoid sinus mass with appearances suggesting a diagnosis of melanoma. Fine-needle aspiration biopsy confirmed the diagnosis. Other differential diagnostic considerations on CT and(More)
OBJECTIVE. In this article, we will review the normal anatomy and imaging features of various neuromuscular abnormalities related to suprascapular neuropathy. CONCLUSION. Suprascapular neuropathy can be difficult to distinguish from rotator cuff pathology, plexopathy, and radiculopathy. Electrodiagnostic studies are considered the reference standard for(More)
Differentiation of nonovarian from ovarian lesions is a diagnostic challenge. MRI (Magnetic Resonance Imaging) of the pelvis provides excellent tissue characterization and high contrast resolution, allowing for detailed evaluation of adnexal lesions. Salient MRI characteristics of predominantly cystic lesions and predominantly solid adnexal lesions are(More)
Cobalt exposure in the hard metal and bonded diamond tool industry is a well-established cause of ILD. The primary theories regarding the underlying mechanism of cobalt related ILD include an immunologic mechanism and an oxidant injury mechanism. Cobalt related ILD may present in subacute and chronic forms and often has associated upper respiratory(More)
