Thoracic paracoccidioidomycosis: radiographic and CT findings.

Paracoccidioidomycosis (PCM) is the most common systemic mycosis in Latin America. Although most cases occur in developing countries, recent immigration patterns and an increase in travel have led to a growing number of PCM cases in the United States and Europe. PCM is caused by the dimorphic fungus Paracoccidioides brasiliensis, and the chronic form may progress to severe pulmonary involvement.

Diffusion MR imaging in central nervous system.

Diffusion-weighted imaging has been used extensively in clinical practice for the early diagnosis of central nervous system conditions that restrict the diffusion of water molecules because it provides information about tumor cellularity or abscesses containing viscous fluid. DTI can detect brain lesions before any conventional imaging. Even though the role of these modalities is well defined for many neurologic lesions that affect the brain, its clinical application in spinal cord diseases is increasing.

Lipoid pneumonia complicating megaesophagus secondary to Chagas disease: high-resolution computed tomography findings.

Purpose: The aim of this study was to evaluate high-resolution computed tomography (HRCT) findings in patients with exogenous lipoid pneumonia after mineral oil aspiration, in association with chagasic megaesophagus.

Materials And Methods: The study included 6 patients aged from 63 to 88 years (mean age, 74.5 y).

Pulmonary amyloidosis with calcified nodules and masses - a six-year computed tomography follow-up: a case report.

Introduction: Pulmonary amyloidosis is an uncommon disease, characterized by extracellular deposition of fibrillary protein in the lungs. It appears in three forms: tracheobronchial, nodular pulmonary, and alveolar septal. There are few reports of long-term observation of primary pulmonary amyloidosis.

Sternal metastasis as an initial presentation of renal cell carcinoma: a case report.

Renal cell carcinoma accounts for 85% of all solid renal tumors in adults. Nearly one quarter of patients has distant metastasis at presentation while another 50% develop metastasis during follow-up. A small percentage of these are solitary metastasis.

Magnetic resonance findings of neurofibromatosis type 2: a case report.

Neurofibromatosis type 2 is an inherited autosomal dominant syndrome, characterized by multiple neoplasms of the central and peripheral nervous system associated with ocular abnormalities. The most common tumor associated with the disease is the vestibulocochlear schwannoma (VIII cranial nerve), and as many as 10% of patients with this tumor have neurofibromatosis type 2. In this report we aim to present a 34-year-old male who was seen for bilateral hearing loss.

Semi-invasive pulmonary aspergillosis in an immunosuppressed patient: a case report.

Background: The authors present the high-resolution computed tomography findings of an immunosuppressed patient with semi-invasive pulmonary aspergillosis.

Case Presentation: The main finding consisted of irregular, thick-walled cavity in the right upper lobe and a mass with soft-tissue attenuation within it and thickening of adjacent pleura. Additional findings were bronchial wall thickening associated with a 'tree-in-bud' pattern.

Telangiectatic adenoma - computed tomography and magnetic resonance findings: a case report and review of the literature.

Telangiectatic adenoma is a new classification of a hepatic lesion. It was previously named telangiectatic focal nodular hyperplasia but it is in fact true adenoma with telangiectatic features. We report here a case of telangiectatic adenoma in a 72-year-old woman.
