Basal cell adenoma is a rare benign salivary gland epithelial tumor, usually involving the parotid gland. We report CT and MR findings of three cases with basal cell adenoma occurring in the parotid gland. The three cases presented here demonstrate a well-circumscribed tumor, which showed a cystic and solid, or the pure solid mass. They were well enhanced(More)
OBJECTIVE The purpose of this article is to assess the technical and clinical outcomes of metallic stent placement in strictures and fistulas involving the carina. MATERIAL AND METHODS We performed a retrospective analysis of patients who had undergone stenting for disease involving the carina. We initially reviewed the symptoms, underlying causes, and(More)
PURPOSE The purpose of this work was to assess the utility of low-dose spiral CT for three-dimensional imaging of the central airways. METHOD Spiral CT was performed in 15 patients using two tube currents (50 and 240 mA), producing 30 CT data sets. Surface-rendered virtual bronchoscopy (VB) and shaded surface display (SSD) images were assessed by three(More)
Alveolar soft-part sarcoma is a rare soft tissue sarcoma of young adults with unknown histogenesis, and the organ most frequently involved in metastasis is the lung. We report the CT findings of three patients of pulmonary metastases of alveolar soft-part sarcoma, which manifested as clearly enhanced pulmonary nodules or masses. On enhanced scans, some of(More)
OBJECTIVES To evaluate the feasibility of diagnosing recurrence of HCC after TACE color-coded iodine CT (CICT) based on arterial phase scans obtained by a dual-energy CT (DECT) scanner. METHODS A CICT scan was acquired from an iodine map after applying material decomposition of the liver tissue and setting a threshold attenuation level for viable tumors.(More)
OBJECTIVE Pulmonary sarcoidosis was recently reported to show the "sarcoid galaxy" sign, indicating large pulmonary nodules composed of coalescent small nodules. The purpose of this study was to review cases of pulmonary tuberculosis showing CT features indistinguishable from the sarcoid galaxy sign. CONCLUSION Large nodules arising from the coalescence(More)
PURPOSE The purpose of this study was to verify whether arthrosonography improves diagnostic accuracy in diseases of the shoulder and provides additional information for therapeutic planning, compared with conventional sonography. METHODS We prospectively studied 113 consecutive patients with chronic shoulder pain. Sonography was performed before and(More)
We describe a case of mesenteric lymphangioma, a very rare disease in adults that is considered to be a developmental abnormality. Since treatment involves complete excision of the mass to prevent recurrence, it is important to understand the exact extent of the tumor prior to surgery. Magnetic resonance imaging (MRI) is the most useful preoperative(More)
PURPOSE To evaluate patients who have a paradoxical response (development of new opacities) to treatment for tuberculous pleural effusion not related to acquired immunodeficiency syndrome. MATERIALS AND METHODS In 16 patients, follow-up chest radiographs (n = 16) and initial (n = 2) and follow-up (n = 9) computed tomographic (CT) scans of the chest were(More)
Behçet's syndrome is a multi-systemic and chronic disorder that affects many organs. It has been suggested that the diagnosis was based on the presence of the 'major' and 'minor' clinical criteria. When thromobophlebitis, arthritis, central nervous system or gastrointestinal lesions are also present. Behçet's syndrome will be thought to be present in the(More)
