Intraoperative sonographic localization of a fractured Supprelin implant in a pediatric patient: a case report.

The subdermal implant is an effective delivery system for the gonadotropin-releasing hormone analog histrelin in the treatment of central precocious puberty. In younger patients, implantation and replacement of the implant is performed under general anesthesia. This obviates the need for frequent intramuscular injections and has been shown to be preferable to patients and families.

Cystic lymph nodes in the lateral neck as indicators of metastatic papillary thyroid cancer.

Objective: To determine whether radiographic findings portend to metastatic disease in patients with papillary thyroid carcinoma (PTC) and whether cystic lymph node metastasis can be recognized by preoperative, ultrasound-guided fine-needle aspiration (FNA).

Methods: We performed a retrospective review of patients with cystic lymph nodes in the lateral neck identified on preoperative ultrasonography between March 1996 and December 2009. Factors examined included demographic information; stage; cytologic and final pathologic findings; and imaging characteristics including location, size, and presence of vascularity and calcifications.

Metastases to intramammary lymph nodes in patients with breast cancer: sonographic findings.

Purpose: To describe the sonographic characteristics of intramammary lymph node metastasis (ILNM) in patients with breast cancer and to assess the value of sonography and sonographically guided fine needle aspiration biopsy (FNAB) in their diagnosis.

Methods: We retrospectively reviewed the charts and films of 19 women with biopsy-documented ILNM who were seen in our breast diagnostic center between December 1999 and July 2003. The sonographic appearance of the nodes was analyzed and correlated with clinical and mammographic findings and with biopsy results.
