Metastases of malignant tumors the internal organs into skin rarely occur, on average in 1–10 % cases. They can be first manifestation process absence signs main disease or show progression confirmed cancer. The article presents clinical cases metastases renal cell carcinoma and adenocarcinoma head neck which currently is rare. Skin are variable their manifestation. In presented cases, resectio...

Objective(s): BONENAVI, a computer-aided diagnostic system, is used in bone scintigraphy. This system provides the artificial neural network (ANN) and bone scan index (BSI) values. ANN is associated with the possibility of bone metastasis, while BSI is related to the amount of bone metastasis. The degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. Therefore, t...

PURPOSE Single dose gadolinium (Gd) enhanced fluid-attenuated inversion recovery (FLAIR) is helpful for visualizing superficial parenchymal metastases. However, the usefulness of FLAIR with a higher dose of Gd is uncertain. The aim of our study was two-folds: first, to prove that the signal to noise ratio (SNR) of small brain metastases is higher than large brain metastases on double-dose (DD) ...

PURPOSE To determine the prevalence and imaging features of bone metastases in patients with gastrointestinal stromal tumors (GISTs). MATERIALS AND METHODS The medical records of 190 patients with pathologically proven GISTs were reviewed, and patients with bone metastases were identified. Computed tomography (CT) scans of the chest, abdomen, and pelvis were examined for features of bone meta...

PURPOSE In pancreatic carcinoma, vascular endothelial growth factor (VEGF) expression at the primary site has been suggested to be a prognostic parameter. We quantitatively analyzed VEGF expression in liver metastases from pancreatic carcinoma and examined the correlation among VEGF expression in liver metastases, clinicopathologic factors, and clinical outcome. EXPERIMENTAL DESIGN The subjec...

BACKGROUND The purpose of this study was to determine the incidence of and survival following brain metastases among women with triple receptor-negative breast cancer. PATIENTS AND METHODS In all, 679 patients with nonmetastatic triple receptor-negative breast cancer diagnosed from 1980 to 2006 were identified. Cumulative incidence of brain metastases was computed. Cox proportional hazards mo...

RATIONALE Detection of skull metastases is as important as detection of brain metastases because early diagnosis of skull metastases is a crucial determinant of treatment. However, the skull can be a blind spot for assessing metastases on routine brain magnetic resonance imaging (MRI). To the best of our knowledge, the finding of skull metastases on arterial spin labeling (ASL) has not been rep...

OBJECTIVE: To present computed tomography findings observed in four patients submitted to radical nephrectomy for renal cell carcinoma who developed pancreatic metastases afterwards. MATERIALS AND METHODS: The four patients underwent radical nephrectomy for stage T1 (n=2) and stage T3a (n=2) renal cell carcinoma. The mean interval between nephrectomy and detection of pancreatic metastases was e...

AIM To evaluate brain metastases volume control capabilities of stereotactic radiosurgery (SRS) through serial magnetic resonance (MR) imaging follow-up. METHODS MR examinations of 54 brain metastases in 31 patients before and after SRS were reviewed. Patients were included in this study if they had a pre-treatment MR examination and serial follow-up MR examinations at 6 wk, 9 wk, 12 wk, and ...
