We describe a 56-year-old woman with a dural arteriovenous fistula involving the transverse sinus in association with a nodule of heterotopic brain tissue in the sinus. This finding is discussed in light of a recent radiologic study of nodules in the transverse sinus.

We report a case of human pulmonary dirofilariasis in a female patient 45-years-old, derived from Rio de Janeiro, Brazil. The chest radiologic finding consisted of single pulmonary nodule located on the left lower lobe that simulated lung tumor. Human pulmonary dirofilariasis might be investigated in nodules that are not malignants and require conclusive diagnosis.

BACKGROUND Bronchiolitis obliterans organizing pneumonia (BOOP) is a distinct pattern of reaction of the lung to injury. It may be idiopathic or secondary to a variety of injuries. The term cryptogenic organizing pneumonia (COP) is used for patients with idiopathic BOOP. In this study we describe clinical and radiologic features of patients with BOOP. METHODS The medical records of 33 patient...

Objective Herein, we report three patients presenting with zoster ophthalmicus caused by varicella virus (VZV) unexpected and novel cervico-medullary findings on magnetic resonance imaging (MRI). Background Zoster opthalmicus involves reactivation of latent VZV in the ophthalmic division trigeminal nerve producing a dermatomal rash. In minority this leads to damage surrounding peripheral nerves...

Complete ureteropelvic junction (UPJ) disruption is a rare finding after blunt abdominal trauma. High clinical suspicion and close attention to imaging studies are needed to avoidmissing a UPJ disruption during initial evaluation. In high grade renal trauma, the best imaging modality to detect collecting system injury and urinary extravasation is computed tomography (CT) scanwith delayed excret...

Peribronchiolar metaplasia is a histologic lesion characterized by fibrosis and bronchiolar epithelial proliferation, affecting peribronchiolar alveolar septa and terminal bronchioles. It has been considered a nonspecific tissue reaction secondary to the action of external factors, such as tobacco smoke and microbes, and is a common histologic finding in several diffuse interstitial lung diseas...

With advances in modern imaging technology, the presentation of an incidentally found adrenal mass (or incidentaloma) has become an increasingly common management scenario for endocrinologists and urologists. The prevalence of adrenal incidentalomas (AI) has been reported as high as 8% in autopsy series and 4% in radiologic series.1,2 As improved imaging techniques become available and the freq...

A 56-year-old woman was found hypothermic on her bathroom floor with a scalp wound, laboratory results indicating long lie. She lethargic and had difficulties finding words. CT scan revealed symmetric posterior temporal lobe hypodensities punctiform hemorrhagic transformation (figure). Radiologic differential diagnosis included encephalitis,1 but CSF showed normal cytosis, xanthochromia, elevat...
