RESUMO
Lung inflammatory myofibroblastic tumor is an uncommon cause of solitary lung nodule (0.7 % of lung tumors). The principal site of inflammatory pseudotumor is the lung, but it can also occur elsewhere in various organs. Although benign, they may be locally very aggressive. Recurrent and multifocal forms have been described. Since they are likely to mimic malignant neoplasms, accurate histopathologic diagnosis is necessary in order to guide appropriate surgical excision and avoid aggressive treatments. We report a case of lung involvement in a young adult with radiologic and pathologic correlations.

In most clinical situations the modern radiological approach to a mediastinal mass consists of performing a CT scan following the chest radiograph. Magnetic resonance imaging is indicated when CT findings are equivocal and as the first-line method in particular situations such as suspected involvement of the posterior mediastinum. In both techniques, tissular components of the mass assessed by density or signal intensity analysis, together with the precise location, are the leading edge of the radiological diagnosis. This review deals mainly with the differential diagnosis of primary neoplasms according to CT and MRI findings.

PURPOSE: The purpose of our study was to evaluate the efficacy of direct intraforaminal steroid injections into the periganglionic space in the treatment of radicular pain. METHODS: Periganglionic infiltrations were performed in 41 patients with acute or chronic radicular pain. Neuroradiologic imaging in all patients showed foraminal stenosis due to degenerative disorders or herniated disk. All injections were performed under CT control. RESULTS: Seventy percent of patients had significant pain reduction, with the greatest success (90% of patients) in those whose foraminal stenosis was due to degenerative disorders; 45% of patients with foraminal herniated disks had pain relief. CONCLUSION: Intraforaminal steroid injection is useful in the treatment of radicular pain, particularly in cases of foraminal degenerative stenosis.
