Radiological Characteristics of Pulmonary Hydatid Cysts

Hydatid disease is a parasitic infection caused by Echinococcus granulosus (EG), characterized by cystic lesions in the liver, lungs, and rarely in other parts of the body. Lungs and liver are the most frequent sites involved. Simultaneous lung and liver cysts are observed in less than 10% of the cases. Hydatid cysts are found more frequently in the lungs of children and adolescents than in their liver, while most cysts in adults are hepatic and relatively few are in the lungs. The hydatid serology results are often negative in patients with isolated pulmonary hydatidosis, and hence may not be helpful in problematic cases. Radiologic approach to the intact, complicated, or ruptured pulmonary hydatid cysts includes a CT scan following the chest radiograph. Thoracic CT may be supplemented with magnetic resonance (MR) imaging and occasionally with ultrasound (US) in clarifying a pleural-based hydatid cyst as extrapleural, pleural, or parenchymal

Chest Imaging Findings in Hospitalized Children with H1N1 Influenza

Objective: The aim was to review the radiological findings and to find new prognostic factors that determine the need for pediatric intensive care unit (PICU) in children with swine-origin influenza (H1N1) virus infection. Methods: Chest X-ray (CXR) and computed tomography (CT) findings of 18 children with laboratory-confirmed H1N1 infection (9 boys, 9 girls) with a median age of 34 (1–216) months were retrospectively evaluated. Results: CXRs were performed in 15 (83.3%) and thorax CT in 7 (38.8%) children. Abnormal findings were detected in 60% of the patients who underwent CXR and 85.7% of the patients who underwent thorax CT. Radiological findings were mostly diffuse, bilateral, and asymmetric. Ground-glass opacity (GGO) (66.6%) was the leading abnormality and was followed by reticulation (38.8%), nodules (27.7%), consolidation only (16.6%), tree-in-bud pattern (11.1%), consolidation with GGO (5.5%), and septal lines (5.5%). Lymphadenopathy (22.2%), air trapping (5.5%), and parenchymal band (5.5%) were other recorded findings. CXR was found to be insufficient to detect subpleural nodules, lymphadenopathies, and sometimes GGO. Only existence of nodules (p=0.04) affected the need for PICU admission. Conclusion: The most common radiological findings in children with H1N1 infection were bilateral, asymmetric GGO with or without associated multifocal areas of consolidation. CXR was insufficient to detect subpleural nodules, lymphadenopathies, and sometimes GGO. The existence of nodules is a bad prognostic factor in determining the need for PICU admission

Imaging of pleural diseases: Evaluation of imaging methods based on chest radiography

Plevra kaynaklı patolojilerin değerlendirilmesinde kullanılan birincil tanı yöntemi konvansiyonel akciğer radyografisidir. Sıklıkla görülen plevra patolojisi plevral kalınlaşma ve efüzyondur. Arka ön akciğer radyografisi (PA, posteroanterior) küçük miktardaki plevral efüzyonu göstermeyebilir. Lateral dekübitus radyografisi ve toraks ultrasonografisi (USG) az miktardaki plevral efüzyonu ortaya koymada daha etkin yöntemlerdir. PA radyografide tek taraflı homojen yoğunluk artışı gösteren olgularda toraks ultrasonografisi plevral ve parankimal patolojilerin ayırıcı tanısında yararlı bilgiler vermektedir. Akciğer radyografisinde saptanan plevral efüzyon veya kalınlaşma altta yatan hastalığı veya parankimal patolojiyi gizleyebilir. Bu nedenle bilgisayarlı tomografi (BT) plevral hastalığın yaygınlığını ve nedenini ortaya koymada yararlı bilgiler sağlamaktadır. BT(koronal ve sagital reformat görüntüler) plevral kalınlaşma veya efüzyonla birlikte bulunan parankimal lezyonların ayırt edilmesini sağlayabilir. Ayrıca BT göğüs duvarı, mediasten ve diyafragma invazyonunu, hiler ve/veya mediastinal lezyonları ayrıntılı olarak gösterebilir. Manyetik rezonans görüntüleme (MRG) standart noninvaziv yöntemlerin yetersiz kaldığı olgularda tamamlayıcı yöntem olarak kullanılabilir.The most commonly employed radiologic method in diagnosis of pleural diseases is conventional chest radiograph. The commonest chestX-Ray findings are the presence of pleural effusion and thickening. Small pleural effusions are not readily identified on posteroanterior chest radiograph. However, lateral decubitus chest radiograph and chest ultrasonography may show small pleural effusions. These are more efficient methods than posteroanterior chest radiograph in the erect position for demonstrating small amounts of free pleural effusions. Chest ultrasonograph may be able to help in distinguishing the pleural pathologies from parenchymal lesions. On chest radiograph pleural effusions or pleural thickening may obscure the visibility of the underlying disease or parenchymal abnormality. Thus, computed tomography (CT) may provide additional information of determining the extent and severity of pleural disease and may help to differentiate malign pleural lesions from the benign ones. Moreover, CT may provide the differentiation of parenchmal abnormalities from pleural pathologies. CT (coronal and sagittal reformatted images) that also show invasion of chest wall, mediastinum and diaphragm, as well as enlarged hilar or mediastinal lymph nodes. Standart non-invasive imaging techniques may be supplemented with magnetic resonans imaging (MRI)
