Exogenous lipoid pneumonia. Clinical and radiological manifestations.

Lipoid pneumonia results from the pulmonary accumulation of endogenous or exogenous lipids. Host tissue reactions to the inhaled substances differ according to their chemical characteristics. Symptoms can vary significantly among individuals, ranging from asymptomatic to severe, life-threatening disease.

Influenza A (H1N1) virus-associated pneumonia: high-resolution computed tomography-pathologic correlation.

Objective: The purpose of this study was to describe the high-resolution computed tomography (HRCT) features of fatal cases of Influenza A (H1N1) virus-associated pneumonia and to correlate them with pathologic findings.

Methods: The study included six adult patients who died following Influenza A (H1N1) virus-associated pneumonia. All patients had undergone HRCT, and the images were retrospectively analyzed by two chest radiologists, who reached decisions by consensus.

Paravertebral mass in a patient with hemolytic anemia: computed tomographic findings.

Extramedullary hematopoiesis is characterized by the presence of hematopoietic tissue outside of the bone marrow and is typically associated with chronic hemolytic anemias. Intrathoracic extramedullary hematopoiesis is a rare and usually asymptomatic condition. The authors report a case of a 57-year-old man with intrathoracic extramedullary hematopoiesis and hereditary spherocytosis.

Tuberous sclerosis with pulmonary lymphangioleiomyomatosis and renal angiomyolipomas. Computed tomographic findings: a case report.

The authors describe a case of a 31-year-old female with tuberous sclerosis, a genetic, rare, variably expressed disease. Clinical symptoms were chest pain, and progressive dyspnea. Computed tomography scan of the chest showed bilateral, diffuse, small thin-walled cysts scattered throughout the lungs characteristic for pulmonary lymphangioleiomyomatosis.

Pulmonary talcosis: imaging findings.

Talc is a mineral widely used in the ceramic, paper, plastics, rubber, paint, and cosmetic industries. Four distinct forms of pulmonary disease caused by talc have been defined. Three of them (talcosilicosis, talcoasbestosis, and pure talcosis) are associated with aspiration and differ in the composition of the inhaled substance.

Lipoid pneumonia in 53 patients after aspiration of mineral oil: comparison of high-resolution computed tomography findings in adults and children.

Objective: To evaluate the high-resolution computed tomography (HRCT) findings in 53 patients with exogenous lipoid pneumonia and to compare the imaging features of adults and children.

Materials And Methods: The study included 35 children and 18 adults. Statistical comparisons of findings in the 2 age groups were performed using either Pearson chi2 or Fisher exact test, as appropriate, at 5% significance level.

Tuberous sclerosis with pulmonary lymphangioleiomyomatosis and renal angiomyolipomas. Computed tomographic findings: a case report.

The authors describe a case of a 31-year-old female with tuberous sclerosis, a genetic, rare, variably expressed disease. Clinical symptoms were chest pain, and progressive dyspnea. Computed tomography scan of the chest showed bilateral, diffuse, small thin-walled cysts scattered throughout the lungs characteristic for pulmonary lymphangioleiomyomatosis.

Pulmonary metastases from primary hepatocellular carcinoma in a 26-year-old patient: a case report.

Hepatocellular carcinoma is a primary tumor of the liver, which usually develops in the setting of chronic liver disease, particularly viral hepatitis. The diagnosis of hepatocellular carcinoma can be difficult, and often requires the use of serum markers, one or more imaging modalities, and histological confirmation. The authors describe a case of a 26-year-old woman with hepatocellular carcinoma and multiple pulmonary metastases.

Pulmonary nocardiosis in the acquired immunodeficiency syndrome, computed tomographic findings: a case report.

The authors describe a case of pulmonary nocardiosis in a 37-year-old man with acquired immunodeficiency syndrome in treatment with antiretroviral drugs. Clinical symptoms were productive cough, hemoptysis and progressive weight loss. A chest x-ray showed a right upper lobe consolidation while the computed tomography demonstrated consolidation with air bronchogram and airspace nodules.

Primary pulmonary mucosa-associated lymphoid tissue lymphoma computed tomography findings: a case report.

Primary pulmonary non-Hodgkin's lymphoma is a very rare neoplasm. It is most frequently represented by the mucosa-associated lymphoid tissue type. We describe a case of a 67-year-old woman who presented with fatigue, mild dyspnea, and consolidation on chest radiograph.

Paracoccidioidomycosis: high-resolution computed tomography-pathologic correlation.

Objective: The purpose of this study was to describe the high-resolution computed tomography (HRCT) features of pulmonary paracoccidioidomycosis and to correlate them with pathologic findings.

Methods: The study included 23 adult patients with pulmonary paracoccidioidomycosis. All patients had undergone HRCT, and the images were retrospectively analyzed by two chest radiologists, who reached decisions by consensus.

Pulmonary hemorrhage syndrome associated with dengue fever, high-resolution computed tomography findings: a case report.

Dengue hemorrhagic fever is an acute infectious disease caused by dengue virus. We described the high-resolution CT findings in a 70-year-old male with the disease, which was diagnosed by clinical examination and confirmed by serological methods. High-resolution CT demonstrated bilateral areas of consolidation with air bronchogram and ground glass opacities, as well as small bilateral pleural effusions.

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.
