BACKGROUND Extramedullary plasmacytoma is a rare plasma cell neoplasm within soft tissue and without bone marrow involvement or other systemic characteristics of multiple myeloma. Primary pulmonary plasmacytoma is a rare type of extramedullary plasmacytoma. CASE PRESENTATION A 48-year-old male with a tumor in the right middle ear was referred to our hospital. A routine chest X-ray was arrange...

Solitary pulmonary nodules are common, often incidental findings on chest CT scans. The investigation of pulmonary nodules is time-consuming and often leads to protracted follow-up with ongoing radiological surveillance, however, clinical calculators that assess the risk of the nodule being malignant exist to help in the stratification of patients. Furthermore recent advances in interventional ...

BACKGROUND Pulmonary glandular papillomas are rare neoplasms, and their very slow or absent growth over time generally facilitates establishing the diagnosis. CASE PRESENTATION In an 84-year-old woman who underwent surgery for sigmoid colon cancer, a growing solitary pulmonary nodule was identified on postoperative follow-up computed tomography. A computer tomography-guided needle biopsy was ...

OBJECTIVE The purpose of this study was to determine whether contrast enhancement features on 3D volumetric gradient-recalled echoMR images allow differentiation of benign from malignant solitary pulmonary nodules. MATERIALS AND METHODS Forty patients with solitary pulmonary nodules (range of greatest diameter, 7-40 mm) detected on CT underwent unenhanced MRI and contrast-enhanced MRI perform...

Asymptomatic solitary pulmonary nodules incidentally revealed by computed tomography has become a serious medical problem. Depending on their diameter, solid, part-solid, or pure ground-glass pulmonary nodules may be observed, diagnosed radiologically/invasively, or resected in accordance with international guidelines. Pure ground-glass nodules, semi-solid lesions, or solid lesions smaller than...
