ABSTRACT
PURPOSE: To assess US, CT and MR findings in women having puerperal ovarian vein thrombosis with clot protrusion into the inferior vena cava. PATIENTS, MATERIAL AND METHODS: We retrospectively reviewed the duplex US (n = 9), CT (n = 5) and MR (n = 5) examinations of 9 patients with 8 right ovarian vein thrombosis, and one left ovarian vein thrombosis. RESULTS: US findings allowed for the diagnosis of ovarian vein thrombosis in all patients in showing enlarged tubular echogenic thrombus within the retroperitoneum with clot protrusion in the IVC in all cases. CT scan and MRI demonstrated ovarian vein thrombosis in all the cases in which it was performed but failed to show a mobile thrombus within the IVC in one patient. CONCLUSION: Duplex US is a reliable technique to show puerperal ovarian vein thrombosis and its extension to the IVC. CT scan and MR imaging can be used to precise the extension to the IVC.

The authors report a case of peritoneal splenosis: the initial diagnosis was established at ultrasound examination and CT scan. This unusual lesion must be suggested when the past history is significant, as asymptomatic should not be removed.

The aim of conformal radiotherapy is to deliver, with high precision, a specific dose (which may be a high dose) to a planning target volume, concurrently with irradiating as little as possible healthy tissue and organs at risk. Radiation therapy may suffer from a number of problems that result in both over- or under-sizing the irradiation fields, making over-rough simplifications of the irradiation ballistics and delivering an insufficient tumoral dose (to spare critical organs and reduce toxicity). One of these problems lies in the accurate positioning of the planning target volume with respect to the irradiation system, thence in the correct execution of the ballistics. In this paper, we describe a system aiming at achieving a higher overall accuracy in the delivery of prostatic boost for carcinoma of the prostate. The system is based on the use of ultrasonic images for measuring the actual position of the prostate just before irradiation. Since these images are registered with pre-operative (CT or MR) images, the position and orientation of the planning target volume is computed with respect to the irradiation system, and can be corrected accordingly. First experiments have been performed on dummies, and the results are discussed.

The authors report a case of a bone metastasis in the thumb initially considered as an arterio-venous angioma revealing a kidney cancer; they insist on its rarity and the difficulties of the diagnosis before osseous biopsy.
