Computed tomographic findings of invasive transitional cell carcinoma in the kidney.
CT findings of 10 cases of transitional cell carcinoma with renal parenchymal involvement were reviewed. CT showed a low-density mass with varying degrees of renal parenchymal involvement. Intrarenal transitional cell carcinomas were characterized by preserved renal contour with abnormalities of the collecting system such as obliteration, entrapment in the tumor, dilatation, and intraluminal mass. Obliteration of the renal sinus fat and poorly defined tumor margin were other characteristic CT features. This study indicated that CT is useful for differentiating transitional cell carcinomas with renal parenchymal involvement from renal cell carcinomas.

Unusual pulmonary metastasis of neuroblastoma: a case report.
A case of unusual pulmonary metastasis of neuroblastoma in an 8-year-old girl is presented. Nodular opacities mimicking pulmonary tuberculosis first appeared in lung apices on chest radiographs. They subsequently developed into extensive consolidations with mediastinal involvement. Metastasis of neuroblastoma was confirmed at autopsy.

Lung cancer associated with punctate calcification: CT and histological correlation.
The etiology of punctate calcifications in lung cancer was evaluated on the basis of CT and histological correlations. Seven cases of lung cancer with punctate calcifications were demonstrated on CT. The patients had undergone surgical resection (five men and two women, 60-70 years old; six adenocarcinomas and one squamous cell carcinoma), and each case was evaluated for its CT appearance and histological findings. The number of calcifications observed on CT varied from one to six. Most were eccentric, but some calcifications in four cases were within the more central portion of the nodules. Overall, in six of seven cases the calcifications were histologically estimated to be due to preexisting old granulomatous fibrotic changes or fragments of bronchial cartilage incorporated within the growing tumors. In only one case were the calcifications psammoma bodies within the tumor. We conclude that punctate calcifications in lung cancers correspond mostly to preexisting calcified granuloma or degenerated bronchial cartilage.
