A 44-year-old woman presented with a right huge axillary mass. Both mammography and ultrasonography revealed a primary cancer of 2.8 cm maximum diameter in the right breast and metastases in the axillary lymph nodes, both being confirmed by aspiration cytology as ductal carcinoma. Right standard radical mastectomy with level III axillary lymph node dissection was carried out. Pathologically, th...

OBJECTIVE To analyze the role of core needle biopsy of axillary lymph nodes with suspected metastases from breast cancer and to correlate the imaging and histologic findings. MATERIAL AND METHODS We retrospectively studied 74 patients diagnosed with breast cancer who underwent ultrasound-guided core needle biopsy of axillary lymph nodes with characteristics suggestive of metastases on ultraso...

OBJECTIVE To assess the contribution of kinetic characteristics in the discrimination of malignant-benign axillary lymph nodes. MATERIAL AND METHODS One hundred fifty-five female patients were included in the study. Following magnetic resonance imaging (MRI) examinations postprocessing applications were applied, dynamic curves were obtained from subtracted images. Types of dynamic curves were...

The status of axillary lymph nodes is a key prognostic indicator in patients with breast cancer and helps guide patient management. Sentinel lymph node biopsy is increasingly being used as a less morbid alternative to axillary lymph node dissection. However, when sentinel lymph node biopsy is positive, axillary dissection is typically performed for complete staging and local control. Axillary u...

The Livermore Torso Phantom, the consensus calibration phantom for measuring internally deposited radioactive materials in the lungs, liver and tracheo-bronchial lymph nodes, has been modified for calibrating direct, in vivo measurements of Am in the axillary lymph nodes. The axillary lymph nodes may contain radioactive material mobilized from a wound in a finger or hand which may confound resu...

Axillary lymph node dissection represents the standard surgical treatment for breast cancer patients with clinically or histologically involved axillary lymph nodes. However, it is associated with significant morbidity, including postoperative arm lymphedema and neuropathy of the involved extremity, and seroma formation in the axilla (Noguchi et al., 1997). Particularly, arm lymphedema develops...

OBJECTIVE This experiment aims to determine the diagnostic value of diffusion-weighted imaging (DWI) in the differentiation of axillary inflammatory lymph nodes from metastatic lymph nodes in rabbit models in comparison with conventional magnetic resonance imaging (MRI). MATERIALS AND METHODS Conventional MRI and DWI were performed at 4 weeks after successful inoculation into the forty female...

OBJECTIVE To evaluate the performance and feasibility of sentinel lymph node biopsy in breast cancer patients using technetium-99m (99mTc) sulphur colloid and gamma probe. METHODS From May 2000 to March 2001, 70 patients with a tumour less than 5 cm with clinically negative axillary lymph nodes underwent sentinel node biopsy followed by standard axillary dissection. 99mTc sulphur colloid was ...

We report on a 59-year-old female patient with an infected vascular graft investigated with 18F FDG-PET/CT. The first of two studies showed FDG activity in the left deltoid and ipsilateral axillary lymph nodes explained by influenza vaccination the day prior. The second 18F FDG-PET/CT showed multiple FDG-avid lymph nodes on both sides of the diaphragm without tracer accumulation at the vaccinat...
