Pulmonary alveolar proteinosis

A 23-year-old man was admitted to the hospital because of dyspnea. Chest X-ray showed reticulo-nodular opacities. The crazy paving appearance on high-resolution CT was highly suggestive of pulmonary alveolar proteinosis. Histologic examination confirmed the diagnosis. Pulmonary alveolar proteinosis is a rare disease but an important diagnosis to make as treatment with pulmonary lavage is curative in a large proportion of patients.

The Holt-Oram syndrome: radiological approach

The clinical and radiological findings in a female child with Holt-Oram syndrome are reported. The most important features are cardiac anomalies associated with typical anomalies of the skeleton of the forearms.

[Benign multilocular cystic nephroma]

A case of benign multilocular cystic nephroma in a young female is presented. The radiological features (urography, ultrasonography, computed tomography and angiography) are not specific for this diagnosis. The differential diagnosis includes a cystic Wilms' tumor in children and a cystic renal cell carcinoma in adults. The final diagnosis is obtained by histological examination of the resected specimen.

Cerebral metastatic malignant melanoma: CT and MR findings with pathological correlation

Cerebral metastases of malignant melanoma usually have a characteristic appearance on CT and MRI. They present as multiple small lesions at the junction of grey and white matter. On CT the lesions are slightly hyperdense with moderate contrast enhancement. On MRI, typical T1 and T2 shortening is seen. In our case these findings were due to abundant presence of melanin without associated hemorrhage.

Atherosclerosic dissection of the cervical internal carotid artery--a case report

Atherosclerosis as a cause of spontaneous dissection in the cervical internal carotid arteries has been described in only a few cases. The authors present a surgically and pathologically proven case of dissection on the base of atherosclerosis of the cervical internal carotid artery. A resection of the pathologic segment with arterial reconstruction by direct anastomosis with a venous patch graft was performed. The postoperative course was uneventful.
