Port-site metastases in gynecological malignancies subsequent to laparoscopy have been reported with an incidence of 1.1-16%. These metastases tend to be disappearing after primary debulking surgery and subsequent primary chemotherapy. Local resection, chemotherapy and/or radiotherapy have been defined in the management of these metastases with enhanced clinical success. However, in extremely rare cases these metastases were also defined very early during neoadjuvant chemotherapy. Herein, we present two ovarian cancer cases which are clinically diagnosed with port site metastasis during neoadjuvant chemotherapy following diagnostic laparoscopy. Although neoadjuvant chemotherapy is sometimes needed in cases of fully advanced ovarian cancers, port-site metastasis may be encountered during neoadjuvant chemotherapy. The possible poor prognosis of these patients, especially those who have ascites, should make us careful in performing diagnostic laparoscopy with preventive measures for port-site metastasis and to start the chemotherapy immediately.

OBJECTIVE: It has been advocated that a reduced injection volume with highly concentrated (1 M) contrast material can produce a sharper bolus peak and an increased intravascular first-pass gadolinium concentration when compared with the use of a lower concentration (0.5 M). A higher concentration would also cause a reduction in dose. The purpose of our study was to test the use of a low dose (0.05 mmol/kg) of gadobutrol in magnetic resonance renography and angiography and compare the findings with a dose of 0.1 mmol/kg. MATERIALS AND METHODS: One-hundred-thirty-four patients referred for magnetic resonance angiography for suspected renovascular disease participated in the study. Contrast enhanced MR renography and angiography were performed after administration of a bolus of 0.1 mmol/kg or 0.05 mmol/kg gadobutrol in randomized patients. The relative signal intensity-time curves of the aorta, peripheral cortex and parenchyma, were obtained. Two radiologists evaluated the angiographic images and evaluated the quality of angiography. RESULTS: The signal intensity with a low dose of gadobutrol was significantly lower in early phases, in the peripheral cortex (for 36, 54, 72 and 90 seconds), the parenchyma (for 36, 54, 72 seconds) and the aorta (for 18, 36, 54, 72 seconds). The decreases in the early phase obtained with a low dose of gadobutrol caused blunter time intensity curves. The difference in the quality scores of the readers for the angiographic images for the use of the two different doses was not statistically significant (p > 0.05). CONCLUSION: A lower dose of gadobutrol can be used for MR renal angiography, but for MR renography the normal dose should be used.
