RESUMEN

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. The interval between the PE and imaging tests was 7 days, and the interval between US and MRI was 2 days. The kappa coefficient was calculated to estimate the agreement between the PE and US and MRI findings and between the US and MRI findings. RESULTS: Significant agreement was observed between PE and US in the diagnosis of synovitis. The only statistically significant agreement between US and MRI was the finding of flexor tenosynovitis; the agreement was moderate. CONCLUSIONS: US has great potential for use in diagnosing synovitis suspected based on a PE. The limited agreement observed between US and MRI, in turn, may suggest a complementary role of these methods.

RESUMEN

Linfoma de colo uterino é uma doença rara. Cerca de 1,0% a 1,5% dos linfomas extranodais se origina no trato genital feminino. A apresentação clínica é inespecífica e a ressonância magnética é importante para a suspeita diagnóstica. Neste artigo relatamos o caso de uma paciente de 80 anos de idade com dor lombar, cuja ressonância mostrou volumosa massa uterina. O diagnóstico final foi de linfoma.


Lymphoma of the cervix is a rare disease. About 1.0% to 1.5% of extranodal lymphomas originates in the female genital tract. The clinical presentation of this condition is nonspecific and magnetic resonance imaging is important for diagnostic elucidation. The present report describes the case of a 80-year-old patient with lumbar pain, whose magnetic resonance imaging showed a large uterine mass. The final diagnosis was lymphoma.

RESUMEN

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. The final diagnosis was silicotuberculosis.

RESUMEN

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. Chest computed tomography showed consolidation in both lungs, with architectural distortion, nodules, interlobular septal thickening, and emphysema, in addition to the right pneumothorax. A lung biopsy revealed yeast consistent with Paracoccidioides brasiliensis. No drainage was needed, and the lung was re-expanded. The patient was treated with antifungal drugs, showed mild improvement, and was referred to outpatient care.

RESUMEN

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. Pulmonary function revealed a mild restrictive ventilatory defect and the chest radiograph demonstrated paracardiac confluence of dense micronodular infiltrate. High-resolution CT scan revealed diffuse ground glass attenuation and septal thickening, more pronounced in lower pulmonary regions, with calcifications along the interlobar septa and subpleural regions. A transbronchial lung biopsy confirmed the diagnosis of PAM.
