“…On dynamic contrast-enhanced images, we found that tuberculomas had thin rimlike enhancement. This finding corresponded to the fibrous capsule and epithelioid granulomas in a study by Sakai et al [22], whereas on pathologic examination the A B central portions that did not become enhanced were composed of caseous necrosis. Round atelectasis is said to be strongly associated with asbestos exposure and may be associated with pleural scarring from tuberculosis and other causes.…”

“…Although alveolar adenomas have no distinct imaging features, the contrast-enhanced CT scan performed in the present study displayed enhancement around a thin-rim of the nodule. Similar features have been identified in tuberculoma patients (14), as well as a previously-reported alveolar adenoma case (1).…”

Abstract. Alveolar adenoma is an extremely rare benign tumor of the lung derived from type II pneumocytes. To date, only a limited number of alveolar adenoma cases have been reported in the literature. These tumors are usually discovered incidentally on radiographic images. However, other tumor types must be excluded when the characteristics of alveolar adenoma are not typical on the radiographic images. Therefore, diagnosis of alveolar adenomas is based on the combination of gross structural analysis and immunohistochemistry. The present study described a case of alveolar adenoma in a 47-year-old female patient. A chest X-ray revealed a pulmonary lesion in the right lower lobe and, subsequently, the patient underwent a right lower lobectomy. Pathological examination of the surgically resected tissue confirmed the initial diagnosis of alveolar adenoma. In addition, intracranial vascular malformations were detected on a computed tomography scan, but the patient did not experience any notable symptoms. Considering the benign nature of the malformations, as determined by digital subtraction angiography, the patient selected to undergo follow-up with observation only. The postoperative course was uneventful and no recurrence of pulmonary lesions was noted after >4 years, while the condition of the intracranial lesion was stable. In conclusion, the current study described a unique case of adenoma alveolar coexisting with intracranial vascular malformations. A literature review of previously-reported alveolar adenoma cases was also conducted.

“…Signal intensity at the center of tuberculomas is low or slightly enhanced, but the signal intensity of the fibrotic rim is markedly enhanced. These MR findings correspond well to those of pathological specimens (Sakai et al 1992;Kono et al 1993;Kusumoto et al 1994;Parmar et al 2000;Chung et al 2000;Schaefer et al 2006). Therefore, when tuberculoma is suspected or attempts are images show nodule as, respectively, low, intermediate, and high signal intensity in the left lower lobe.…”

“…In rare cases, areas of diminished attenuation are seen, which represent caseous necrosis. The latter may be identified as tuberculoma, a nodule with a relatively low signal intensity in comparison with that of other pulmonary nodules on T2-weighted SE or turbo SE images (Sakai et al 1992;Kono et al 1993;Kusumoto et al 1994;Parmar et al 2000;Chung et al 2000;Schaefer et al 2006). In addition, several investigators have reported on typical MR findings of tuberculoma on post-contrast-enhanced T1-weighted images known as "thin-rim enhancement" sign (Sakai et al 1992) (Fig.…”

Since the publication of the Radiologic Diagnostic Oncology Group Report (RDOG) in 1991, the clinical application of pulmonary magnetic resonance (MR) imaging to patients with lung cancer has been limited. MDCT has been much more widely available for staging of lung cancer in clinical situations. Traditionally, FDG-PET or PET/CT is the only modality that reveals biological glucose metabolism of lung cancer, and ventilation and/or perfusion scintigraphy is the only modality that demonstrates pulmonary function. However, recent advances of MR systems and utilization of contrast media make it possible to overcome the limitation of chest MR imaging. Therefore, in the last years, several investigators have demonstrated the significant comprehensive potential of MR imaging to substitute for MDCT and nuclear medicine examinations in lung cancer staging. Currently, MR imaging in lung cancer patients can be applied for (1) detection of pulmonary nodules, (2) characterization of solitary pulmonary nodules, and (3) assessment of TNM classification in routine clinical practice. We believe that further basic studies, as well as clinical applications of newer MR techniques, will play an important role in the future management of patients with lung cancer including MRI.
