Bilateral Pyosalpinx Causing Obstructive Hydronephrosis: A Multimodality Imaging Approach with the Emphasis on the Diffusion-weighted Magnetic Resonance Imaging.

A 40-year-old female, who was being treated for a urinary tract infection, was admitted to the hospital due to a gradually increasing left flank colic pain. An ultrasound investigation detected right-sided hydronephrosis, and a computed tomography scan additionally showed large cystic changes in both the fallopian tubes, which were compressing the ureters and thus causing hydronephrosis. Subsequently, magnetic resonance imaging was performed, which demonstrated fluid-fluid levels inside the cystic changes.

The role of contrast enchanced axillary ultrasonography in early breast cancer patients.

The most important prognostic factor for the patients with breast cancer are metastases to axillary lymph nodes (ALNs). Preoperative ultrasound (US) combined with fine needle aspiration biopsy (US-FNAB) has been proved to be the most reliable method to detect nonpalpable axillary metastases in patients with breast cancer. Our study was aimed to examine the value of US contrast agent (CA) SonoVue in the US examination of the axilla for the detection of axillary lymph node (ALN) metastases in breast cancer patients.

Low performance of the MSKCC nomogram in preoperatively ultrasonically negative axillary lymph node in breast cancer patients.

Background And Objectives: In order to predict the nonsentinel lymph node (NSLN) metastases in sentinel lymph node (SLN) positive patients a nomogram was created at the Memorial Sloan Kettering Cancer Centre (MSKCC). The aim of our study was to validate the MSKCC nomogram in patients grouped by the preoperative ultrasound (US) examination of the axillary lymph nodes.

Methods: The MSKCC nomogram was validated separately in three groups of patients: (US-0) only clinically preoperatively negative axillary lymph nodes (126 patients), (US-1) US negative axillary lymph nodes (109 patients), and (US-2) US suspicious but fine needle aspiration biopsy (FNAB) negative axillary lymph nodes (41 patients).

Patients with preoperatively ultrasonically uninvolved axillary lymph nodes: a distinct subgroup of early breast cancer patients.

Introduction: Ultrasound (US) preoperative examination of the axillary lymph nodes combined with the fine needle aspiration biopsy (FNAB) is often used in order to reduce the number of sentinel lymph node (SLN) biopsy procedures in clinically node negative breast cancer patients. The pathohistological characteristics of the ultrasonically negative axillary lymph nodes in clinically negative axillary lymph nodes are not known. The aim of our study was to compare the pathohistological characteristics of ultrasonically uninvolved axillary lymph nodes (US group) versus clinically uninvolved axillary lymph nodes (non-US group) in SLN biopsy candidates.

Role of ultrasound in the preoperative staging of patients with breast cancer.

The aim of this study was to evaluate the ability of axillary ultrasound (US) and US-guided fine-needle aspiration biopsy (FNAB) to detect axillary LN metastases. Between January 2001 and September 2003, axillary US was performed in 165 patients with cytologically or histologically proven breast cancer and clinically non-palpable axillary LNs. In patients with US suspicious LNs, US-guided FNAB was performed and patients with cytologically proven malignant LNs proceeded directly to the ALND.

Minimal risk of macrometastases in the non-sentinel axillary lymph nodes in breast cancer patients with micrometastatic sentinel lymph nodes and preoperatively ultrasonically uninvolved axillary lymph nodes.

Micrometastases in the sentinel lymph node (SLN) carry a considerable risk of macrometastases in the non-sentinel lymph nodes (NSLN), resulting in axillary lymph node dissection (ALND). Preoperative ultrasound (US) examination of the axillary lymph nodes combined with a fine-needle aspiration biopsy (FNAB) has been proved to discover metastases in the axillary lymph nodes. The aim of our study was to assess the risk of macrometastases in NSLN in patients with micrometastatic SLN after a preoperative US examination of the axillary lymph nodes.
