Pulmonary complication of novel influenza A (H1N1) infection: imaging features in two patients.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Novel influenza A (H1N1) virus is the pathogen of recent global outbreaks of febrile respiratory infection. We herein report the imaging findings of pulmonary complication in two patients with novel influenza A (H1N1) infection. The first patient without secondary infection showed the ill-defined ground-glass opacity nodules and patch areas of ground-glass opacities. The second patient with secondary pneumococcal pneumonia showed areas of lobar consolidation in the right middle lobe and left lower lobe and ground-glass opacities.

Typical and atypical manifestations of intrathoracic sarcoidosis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Sarcoidosis is a systemic disorder of unknown cause that is characterized by the presence of noncaseating granulomas. The radiological findings associated with sarcoidosis have been well described. The findings include symmetric, bilateral hilar and paratracheal lymphadenopathy, with or without concomitant parenchymal abnormalities (multiple small nodules in a peribronchovascular distribution along with irregular thickening of the interstitium). However, in 25% to 30% of cases, the radiological findings are atypical and unfamiliar to most radiologists, which cause difficulty for making a correct diagnosis. Many atypica...

18F-fluorodeoxyglucose PET/CT in a patient with esophageal and genital leiomyomatosis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Diffuse esophageal leiomyomatosis is a rare benign tumor, which can be associated with leiomyoma in female genital tracts involving the uterus, vagina, and vulva. Alport syndrome, an inherited disorder that includes the kidneys, eyes, and sensorineural hearing loss, is also rarely associated with these multiple leiomyomatosis. In our case, (18)F-fluorodeoxyglucose positron emission tomography/computed tomography was used to distinguish esophageal and genital leiomyomatosis from malignant masses.

The current practice of transarterial chemoembolization for the treatment of hepatocellular carcinoma.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Despite remarkable advancement in the surveillance and treatment of hepatocellular carcinoma (HCC) and the availability of novel curative options, a great proportion of HCC patients are still not eligible for curative treatment due to an advanced tumor stage or poor hepatic functional reserve. Therefore, there is a continuing need for effective palliative treatments. Although practiced widely, it has only recently been demonstrated that the use of transarterial chemoembolization (TACE) provides a survival benefit based on randomized controlled studies. Hence, TACE has become standard treatment in selected patients. TAC...

Intracranial fibroxanthoma in an infant: a case report.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We present a case of an infantile fibroxanthoma that arose from the cranial dura mater in a six-month-old girl with US, MRI and PET/CT features that mimicked a meningioma. The tumor appeared as a large, well-circumscribed echogenic mass in the right parieto-occipital area on US. The tumor was seen as isoattenuated to slightly hypoattenuated on pre-contrast CT scan and as hypometabolic on PET/CT. As seen on T2-weighted image, the mass was heterogeneously hyperintense to the gray matter. The mass was isointense on T1-weighted image and homogeneously strongly enhanced on contrast enhanced T1-weighted image. PMID: 19568470...

Nasal chondromesenchymal hamartoma: CT and MR imaging findings.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report CT and MR imaging findings for a case of nasal chondromesenchymal hamartoma occurring in a 19-month-old boy. A nasal chondromesenchymal hamartoma is a rare benign pediatric hamartoma that can simulate malignancy. Although rare, knowledge of this entity is essential to avoid potentially harmful therapies.

Pulmonary venous malformation in a 4-year-old boy: a case report.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report a case of a pulmonary venous malformation in a 4-year-old boy who presented with recurrent pneumonia. A radiograph revealed a right infrahilar mass and a hyperlucent right lung. Computed tomography (CT) demonstrated a mass containing intensely enhancing areas and multiple phleboliths located in the right lower lobe and encasing the right bronchus and right inferior pulmonary vein. Magnetic resonance imaging (MRI) precisely revealed the mass demarcation. A right lower lobectomy was performed and a pathological examination confirmed the diagnosis of a venous malformation. To the best of our knowledge, a venous malf...

Radiological findings of extensively drug-resistant pulmonary tuberculosis in non-AIDS adults: comparisons with findings of multidrug-resistant and drug-sensitive tuberculosis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSION: By observation of multiple cavities, nodules and bronchial dilatation as depicted on CT in young patients with acid-fast bacilli (AFB) positive sputum, the presence of MDR TB or XDR TB rather than DS TB can be suggested. There is no significant difference in imaging findings between patients with XDR TB and MDR TB. PMID: 19412508 [PubMed - in process] (Source: Korean J Radiol)
