Castleman Disease Presenting with Jaundice: A Case with the Multicentric Hyaline Vascular Variant

Castleman disease (CD) is a rare lymphoproliferative disorder of unknown etiology with different clinical manifestations. A previous healthy 50 year-old man was hospitalized for right upper quadrant (RUQ) abdominal pain. He had jaundice and a 1 cm-sized lymph node in the right supraclavicular area. Pancreas and biliary computed tomography (CT) showed masses at the right renal hilum and peripancreatic areas. Positron emission tomography (PET) showed widespread systemic lymphadenopathy. Excisional biopsy of the right supraclavicular node revealed a hyaline vascular variant of CD. Corticosteroid therapy was started and the extent of disease decreased. We here report a case of multicentric CD, the hyaline vascular variant, presenting with jaundice, diagnosed by excisional biopsy and successfully treated with corticosteroids.

The CT Findings of Bronchial Anthracofibrosis: Comparison of Cases with or without Active Tuberculosis

PURPOSE: To assess the CT findings of bronchial anthracofibrosis with or without active tuberculosis. MATERIALS AND METHODS: Analysis of the CT scans of 35 patients with bronchoscopically proven anthracofibrosis revealed that 25 were negative for active tuberculosis and ten were positive. Bronchial and pleural lesions, pulmonary parenchymal lesions, and mediastinal/hilar lymph nodes were retrospectively evaluated. RESULTS: Common radiologic findings of anthracofibrosis included diffuse bronchial narrowing (50%), wall thickening (37%), and mass-like soft tissue density in central bronchi (8%). The right middle lobe was most commonly involved (31%). Common findings of pulmonary parenchymal lesions included consolidation (37%), atelectasis (31%), and ground-glass opacity (10%). These bronchial or pulmonary parenchymal findings were common in patients with or without active tuberculosis. Findings of multiple poorly defined small nodules, including branching opacities and consolidation with internal low density were seen only in patients with active tuberculosis (p<0.01), while enlarged mediastinal or hilar lymph nodes were frequently observed in patients with or without active tuberculosis. Necrotic lymph nodes were present only in those with active tuberculosis (p<0.05). CONCLUSION: When CT scans depict central bronchial narrowing, wall thickening, or mass-like soft tissue density with atelectasis or consolidation, especially in older patients without a distinct central lung mass lesion, anthacofibrosis should be included in the differeatial diagnosis. When multiple poorly defined small nodules, including branching opacities, consolidation with internal low density or necrotic lymph nodes are observed, the possibility of concomitant active tuberculosis should be considered.

CT Findings of Kimura's Disease Involving Thorax: Case Report

Kimura's disease is a benign chronic inflammatory condition with good prognosis, commonly involving the head and neck area. With regard to thoracic manifestation, however, the information contained in the literature is limited. The diagnosis of Kimura's disease on the basis of imaging is difficult, especially in thoracic cases manifesting as lymphadenopathy. The purpose of this report is to illustrate and discuss a thoracic case of the disease manifesting as lymphadenopathy.

Coil Embolization in Right Superior Thyroid Artery Pseudoaneurysm by Stab Wound

A case of coil embolization in right superior thyroid artery pseudoaneurysm by stab wound is reported. A fifty-six-year old female, laceration and some bulging in right neck side. Aortic arch angiography, right common carotid angiography was done. Angiography shows 4 2 cm sized right thyroid artery pseudoaneurysm (Fig. 1) and (Fig. 2). We selected right superior thyroid artery by 3F micorofert (CooK, Bloomington, Ind.) and embolized by 2 4 mm (diameter), 2 cm (length) sized micro tornaido coil (CooK, Bloomington, Ind.). Post procedure right common carotid angiography was done. Angiography shows no visualized right thyroid artery pseudoaneurysm (Fig. 3).
