CONTEXT Endemic area and iodine supplementation may affect the pathogenesis of the nodule which commonly occurs in endemic thyroid enlargement due to iodine deficiency. AIMS To establish pathological changes in solitary solid and larger nodule of the thyroid in endemic area. SETTING AND DESIGN Retrospective study in Surgical Department of University Hospital. METHODS AND MATERIAL We deter...

BACKGROUND/AIM Our purpose in this retrospective study was to determine the ratio of unexpected [metastases within the coverage area of thorax computed tomography (CT)] and unknown (metastases out of the coverage area of thorax CT) metastases by positron emission tomography/CT (PET/CT) in patients with newly diagnosed non-small cell lung cancer (NSCLC) who had no defined metastatic lesion, and ...

Ectopic meningiomas are rare, and primary pulmonary meningiomas are even rarer. Most of them are benign, but malignant primary pulmonary meningiomas have been reported. They usually present as a solitary pulmonary nodule, and primary lung cancer or metastasis may be suspected on imaging. Here, we report a case of a 63-year-old female with primary pulmonary meningioma. The chest CT scan revealed...

Pulmonary nodules are of high clinical importance, given they may prove to be an early manifestation of lung cancer. Pulmonary nodules are small, focal, radiographic opacities that may be solitary or multiple. A solitary pulmonary nodule is a single, small (<-30 mm in diameter) opacity. Larger opacities are called masses and are often malignant. As imaging techniques improve and more nodules ar...

A symptomless 42 year old man with a smoking history of 40 pack-years presented with a solitary pulmonary nodule highly suggestive of lung cancer. Wedge resection proved it to be an eosinophilic granuloma. No other localizations of eosinophilic granuloma were found, and none developed during a 3 yr follow-up.

A symptomless 58 year old man had an eosinophilic granuloma of the lung that presented as a solitary pulmonary nodule rather than the usual diffuse reticulonodular shadow on the chest radiograph. Only one previous case presenting in this way has been described.

Background: Pulmonary nodular excavation should firstly evoke tuberculosis or necrosis broncho-pulmonary tumor, particularly: epidermoid carcinoma. The case discussed here illustrated these difficulties in patients with rheumatoid arthritis (RA). Case Presentation: A 63-year-old woman was presented with a-three-year history of RA and a recent discovery of an excavated pulmonary nodule. Initi...

Primary cutaneous CD30+ T cell lymphoma is rare lymphoma originally in and confined to the skin. These lymphomas usually present as a large solitary and often ulcerated nodule. Its prognosis is a good and has a good response to radiotherapy. We report a 34- year- old man who had primary cutaneous CD30+T cell lymphoma on his face, which presented as an ulcerated nodule.

OBJECTIVE The purpose of our study is to improve radiologists' understanding of the clinical issues involved in making a diagnosis and to guide further diagnostic workup and treatment of solitary pulmonary nodules (SPNs). CONCLUSION Information on the morphologic and hemodynamic characteristics of SPNs provided by dynamic helical CT, with high specificity and reasonably high accuracy, can be ...
