Contrast-Enhanced Color Doppler Ultrasonography for Preoperative Evaluation of Sentinel Lymph Node in Breast Cancer Patients.

Background: Sentinel lymph node (SLN) biopsy is the standard of care for breast cancer patients with non-palpable axillary lymph nodes. We evaluated the usefulness of contrast-enhanced ultrasonography in preoperative detection of malignant SLNs.

Methods: 50 patients with breast cancer (median age: 60 years) underwent a color power Doppler ultrasonography with intravenous contrast (Sonovue®) preoperatively, and findings suggestive of metastatic disease to the SLN were documented.

"Solitary" necrotic nodule of the liver: an enigmatic entity mimicking malignancy.

Aim: The aim of the study is to further investigate the clinicopathological features of solitary necrotic nodules.

Material And Methods: Twenty-three archived cases of solitary necrotic nodule of the liver, which were preoperatively misdiagnosed as liver metastases were studied. The pathological findings were correlated with the clinical data of the patients.
