[Ectopic thyroid basi-lingual: A case report].

Introduction: The thyroid ectopic gland is a rare anomaly, especially when it's a lingual thyroid. It is characterized by aspecific clinical presentation, causing a diagnostic problem. The diagnosis is based on a combination of imaging techniques as well as histological examination. Case presentation: We are presenting a case of a patient with thyroid basi-lingual treated surgically. Discussion: The low incidence of ectopic lingual thyroid , and their clinical variability requires radiological and isotopic investigations. Conclusion: The diagnosis of this disease is primarily histological. The management of these ectopic thyroid is surgical.

[Vertebroplasty and kyphoplasty under dual guidance (CT and fluoroscopy): radiation dose to radiologist. A comparative study]. / Étude dosimétrique comparative de la vertébroplastie et de la kyphoplastie sous double guidage: scanner et fluoroscopique.

OBJECTIVES: The goals of this study is to evaluate and compare the irradiation received by the practitioner when performing percutaneous vertebroplasty or kyphoplasty guided by CT and fluoroscopy, for precise anatomical sites. METHODS: For each intervention, radiothermoluminescent dosimeters were carefully positioned on both orbitals, both hands, and both ankles of the practitioner. RESULTS: Twenty-four vertebroplasties were performed in 18 patients and nine kyphoplasties on seven patients. The anatomical site that is most exposed to radiation is the right hand. The two other sites subjected to irradiation are the left hand and the left orbital. This study demonstrates a significant correlation between the irradiation dose and fluoroscopy duration, reflecting both the quantity of primary-beam radiation and backscattered radiation. CONCLUSION: The radiation dose to radiologist is more important for kyphoplasty procedures than vertebroplasty.

[Percutaneous brachial access: a few simple considerations]. / Abord brachial percutané: quelques règles simples.

This letter is with regards to the recently published article by Vidal et al. in the Journal Français de Radiologie Médicale. A clarification of US and venographic techniques of brachial venous catheterization and related complications are presented. The main indications for PICC line and subcutaneous port placement are described.

Ultrasound-guided lymph node sampling in the initial management of breast cancer.

Ultrasound-guided fine needle sampling is proving very useful for avoiding surgical biopsy of the sentinel lymph node for N+breast cancer. Because of its high specificity, cytology is sufficient in most cases. Focal or diffuse cortical thickening or the absence of the echogenic hilum irrespective of the size and shape of the lymph node are ultrasound signs which should be taken into account. The status of the lymph nodes in axillary and extra-axillary sites has an impact on the later management of patients and reduces the length of time for secondary lymph node dissection and adjuvant therapy, as one third of sentinel ganglion procedures can be avoided. It should be possible to optimise identification of the sentinel lymph node by the intradermal injection of ultrasound contrast agent. The cost/effectiveness ratio is positive but unknown and should be assessed in the initial management of breast cancer.
