The case of a 76-year-old woman presenting with focal liver lesions suggesting liver metastasis on CT is reported. A control CT performed one week later showed a normal liver. Biopsy revealed the diagnosis of focal liver steatosis. The final diagnosis of transient focal steatosis is proposed.
Osler-Rendu-Weber disease, or hereditary hemorrhagic telangiectasia, is a vascular disease with autosomal dominant transmission. The liver is involved in 31% of patients with hereditary hemorrhagic telangiectasia (1). It appears that the lesions uncommonly causes serious disease. We report the imaging findings and the therapy in a case with extensive telangiectasis in the liver.
Pulmonary embolism is a leading cause of morbidity and mortality that can occur in many clinical situations. For several years, spiral CT has represented a relatively non invasive modality for diagnosing this common disease. The present article is reviewing the CT features of acute and chronic pulmonary embolism, the technical aspects of spiral CT acquisition, the diagnostic accuracy and major limitations and pitfalls of the technique.
A case of hepatic arterial haemorrhage after percutaneous biliary drainage catheter placement is presented. Temporary control of the haemorrhage was obtained by placement of a larger drainage catheter which tamponaded the bleeding artery. Hepatic angiography followed by transcatheter embolotherapy provided a definitive control of bleeding.
The value of a semi-automated program for volumetric measurements was tested in 53 patients with liver lesions. Three different radiologists performed 10 measurements on a liver lesion in each patient. The variances of the measurements were calculated. There was no difference in intra- and interoperator variance of the measurements. If the diameter of the liver lesion exceeded the slice thickness, the different measurements became more reliable and more reproducible. The semi automation of the volume measurements makes its use in daily clinical practice possible. Volume measurement can be interesting in the follow-up and evaluation of the treatment on tumor reduction. However further and more thorough investigation is needed to test the clinical usefulness of the program.
We report a case of malignant maxillar ameloblastoma. A review of literature is presented. The unusual clinical behavior and the non specific presentation on CT of our case are discussed.
Optimal radiological visualisation of laryngeal carcinoma demands for a tailored imaging technique. The technique for computed tomography of the larynx is reviewed, and imaging findings in laryngeal carcinoma are described. The application of CT-findings for selection of patients into the favourable group for radiation therapy is discussed. The use of CT in the follow-up of irradiated laryngeal carcinoma is reviewed.
