Chikungunya Fever: Comparison Study of Synovitis and Tenosynovitis of the Hands and Wrists Using Physical Examination, Ultrasound, and MRI Findings.

Objectives: To compare musculoskeletal changes on a physical examination (PE), ultrasound (US) and magnetic resonance imaging (MRI) of the hands and wrists of patients with Chikungunya fever (CF).

Methods: The sample consisted of 30 patients in the chronic phase of CF. The sites analyzed were the interphalangeal (IP), metacarpophalangeal (MCP) and wrist/mediocarpal (WMC) joints and periarticular soft tissue.

Computed tomography and magnetic resonance enterography findings in Crohn's disease: what does the clinician need to know from the radiologist?

The purpose of this pictorial essay was to discuss and illustrate computed tomography and magnetic resonance enterography findings in patients with Crohn's disease. These noninvasive and easily performed methods for the evaluation of Crohn's disease are useful for differentiating between active and fibrotic bowel disease, and can help to guide treatment (medical vs surgical). Although inflammatory and fibrostenotic findings of Crohn's disease may overlap, computed tomography and magnetic resonance enterography can help to identify the presence, extent, and severity of active inflammation that may respond to medical therapy, and the existence of fistulas and fibrostenosis that may benefit from surgical management.

Cavitated conglomerate mass in silicosis indicating associated tuberculosis.

Silicosis is the most common occupational lung disease worldwide. It leads to respiratory impairment and may have associated infections that decrease pulmonary function. We describe the case of a 55-year-old man with chronic silicosis who presented with hemoptysis and a cavitated conglomerate mass.

Pulmonary alveolar microlithiasis: a case report with emphasis on imaging findings.

Pulmonary alveolar microlithiasis (PAM) is a rare disease characterized by the presence of small calculi in the alveolar space. The authors report a case of a 21-year-old man with a 2-year history of shortness of breath on exertion and dry cough. Physical examination was altered only for crackles at auscultation.

Spontaneous pneumothorax as an atypical presentation of pulmonary paracoccidioidomycosis: a case report with emphasis on the imaging findings.

We describe the case of a 45-year-old male with pulmonary paracoccidioidomycosis and spontaneous pneumothorax. The patient presented to the hospital with sudden and intense chest pain accompanied by dyspnea and had a six-month history of dry cough, weight loss, and progressive dyspnea on exertion. Chest X-ray showed a small right pneumothorax, bilateral nonhomogeneous opacities, and emphysematous areas in the lung base.
