    <jats:sec><jats:title>Background</jats:title><jats:p> Prevertebral calcific tendinitis results from calcium hydroxyapatite crystal deposits in the longus colli muscles, which induce symptoms similar to some surgically-treated conditions, such as retropharyngeal abscesses. Imaging techniques are critical for accurate diagnosis. </jats:p></jats:sec><jats:sec><jats:title>Purpose</jats:title><jats:p> To describe the computed tomography (CT) findings associated with prevertebral calcific tendinitis. </jats:p></jats:sec><jats:sec><jats:title>Material and Methods</jats:title><jats:p> Retrospective analysis performed in an 18-month period, searching for patients with neck CT and reports with diagnosis of “calcific longus collis tendinitis” or “prevertebral calcific tendinitis”. CT images and clinical data available in the medical records were analyzed. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> One hundred and thirty-four examinations were performed in the period studied. Nine patients who fulfilled inclusion criteria were identified and their CT imaging characteristics are presented. Six presented with calcific deposits in the right longus colli muscle. CT matched the clinical pain lateralization in all cases. Eight patients had no significant enhancement post injection of contrast media. </jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p> Prevertebral calcific tendinitis is a cause of acute cervical pain that clinically mimics a retropharyngeal abscess, however on neck CT has a characteristic appearance. Correct identification of this pathologic condition will help avoiding unnecessary invasive procedures. </jats:p></jats:sec>

    <jats:p>Abstract Objective: The aim of this study was to evaluate the high-resolution computed tomography (HRCT) findings in patients diagnosed with metastatic pulmonary calcification (MPC). Materials and Methods: We retrospectively reviewed the HRCT findings from 23 cases of MPC [14 men, 9 women; mean age, 54.3 (range, 26-89) years]. The patients were examined between 2000 and 2014 in nine tertiary hospitals in Brazil, Chile, and Canada. Diagnoses were established by histopathologic study in 18 patients and clinical-radiological correlation in 5 patients. Two chest radiologists analyzed the images and reached decisions by consensus. Results: The predominant HRCT findings were centrilobular ground-glass nodules (n = 14; 60.9%), consolidation with high attenuation (n = 10; 43.5%), small dense nodules (n = 9; 39.1%), peripheral reticular opacities associated with small calcified nodules (n = 5; 21.7%), and ground-glass opacities without centrilobular ground-glass nodular opacity (n = 5; 21.7%). Vascular calcification within the chest wall was found in four cases and pleural effusion was observed in five cases. The abnormalities were bilateral in 21 cases. Conclusion: MPC manifested with three main patterns on HRCT, most commonly centrilobular ground-glass nodules, often containing calcifications, followed by dense consolidation and small solid nodules, most of which were calcified. We also described another pattern of peripheral reticular opacities associated with small calcified nodules. These findings should suggest the diagnosis of MPC in the setting of hypercalcemia.</jats:p>

    <jats:title>Abstract</jats:title><jats:p>Acute cholecystitis (AC) is a frequent complication of biliary cholelithiasis. Although ultrasound is the first diagnostic imaging procedure, frequently the initial imaging modality is computed tomography (CT). Therefore, familiarization of CT findings in AC and potential related complications are extremely important. This pictorial essay reviews a broad spectrum of complications related to AC and its key findings in CT.</jats:p>
