Imaging of lung cancer: Implications on staging and management

Lung cancer is one of the leading causes of cancer-related deaths. Accurate assessment of disease extent is important in deciding the optimal treatment approach. To play an important role in the multidisciplinary management of lung cancer patients, it is necessary that the radiologist understands the principles of staging and the implications of radiological findings on the various staging descriptors and eventual treatment decisions

An Unusual Cause of the Ring Artifact on Transaxial CT Images

Artifacts and image quality are two sides of the same coin. The ring artifact is scanner-based and caused mainly by either a miscalibrated element or a defective element of a detector row. We describe a rare cause of the ring artifact that appeared on a transaxial CT image because of a loose electronic contact. To our knowledge, this particular cause of the ring artifact has not been described in literature. </p

Bilateral renal metastases in a case of Merkel cell carcinoma

Merkel cell carcinoma is a primary neuroendocrine carcinoma of the skin. It is a highly aggressive tumor which commonly metastasizes to lymph nodes, liver, lung and bone. The diagnosis is based on histology and immunohistochemistry. Renal metastasis, with sparing of other common sites of hematogenous spread (lung and liver), is a unique feature of this case

Intense focal Fluoro-deoxyglucose uptake in the lungs with no corresponding computed tomography abnormality

Scenario such as uptake of Fluoro-deoxyglucose (FDG) with no corresponding abnormality on computed tomography (CT) is encountered in case of brown fat uptake. However, it is rarely encountered in the lung parenchyma. We report one such case of a focal FDG uptake in the lung parenchyma with no corresponding CT abnormality, in a treated case of hypopharyngeal cancer

Management of locally advanced primary mediastinal synovial sarcoma

Primary mediastinal synovial sarcoma (PMSS) is a relatively rare disease, and patients are treated predominantly with surgery for resectable disease. Management of locally advanced borderline resectable and unresectable PMSS is not only challenging but also lacks standard guidelines. We present three patients with PMSS, who were unresectable or borderline resectable at presentation and were treated with neoadjuvant chemotherapy followed by surgery and postoperative radiotherapy
