Purpose: We investigated whether the preoperative ultrasound (US)-guided hookwire localization for nonpalpable cervical masses allows surgeons to find these masses more easily and more confidently.
Methods: Eight patients underwent preoperative US-guided hookwire insertion for nonpalpable cervical masses at our institution between January 2008 and January 2011. Cervical masses were detected by US or CT, and seven of the eight patients underwent US-guided fine-needle aspiration. Before surgery, a radiologist inserted a hookwire into the cervical mass, under US guidance.
Results: US-guided hookwire insertion took about 5-10 minutes and was successful in all cases without complications. Final pathologic results were metastatic papillary thyroid cancer (n = 4), no metastasis (n = 1), parathyroid adenoma (n = 1), tuberculosis (n = 1), and Kikuchi's disease (n = 1).
Conclusions: Preoperative US-guided hookwire insertion in nonpalpable cervical lesions provides surgeons with an effective means of lesion location.

Ultrasound-guided hookwire localization of non palpable cervical lymphadenopathy: A case-control study of operative time.
Cancer Med

Radiology Department, Brest University Hospital, Brest, France.
Objective: We aimed at evaluating the impact of ultrasound-guided (US) hookwire localization of nonpalpable cervical lymphadenopathy on operating time.
Design And Methods: Retrospective case control study (January 2017 and May 2021) of 26 patients with lateral nonpalpable cervical lymphadenopathy undergoing surgery with (H+) and without (H-) per operative US-guided hook-wire localization. Operative time (general anesthesiology onset, hookwire placement, end of surgery) and surgery-related adverse events data were collected.
12-year review of MRI-detected breast cancers. How often was a diagnosis of malignancy established using targeted ultrasound and standard 14-gauge core biopsy?

Introduction: This retrospective study aimed to determine the percentage of MRI-detected breast cancers diagnosed using targeted ultrasound and standard 14-gauge (14g) biopsy in the setting of an Australian breast MRI service. This is of clinical relevance because malignancies not identifiable on mammography or by ultrasound may then require more invasive, technically demanding and costly MRI-guided interventional procedures, usually by large-core vacuum-assisted biopsy (VAB) or hook-wire localisation with open surgical biopsy.
Methods: On review of the 12-year period 2006-2018, we identified 67 new breast cancer events in 64 women where the diagnosis was made on the basis of the MRI scan findings either alone (n = 60) or in combination with a concurrent mammogram (n = 7), with no recorded clinical abnormality.

A total of 425 wire localized biopsies for non-palpable breast lesions found by screening (n = 169) or clinical (n = 256) mammography between 1986-1990 are reviewed with reference to the biopsy success rate with different localization techniques, the positive predictive value of the mammographic findings and the staging and treatment of carcinomas in the clinical and screening groups. Specimen radiographs were available for review in 371 cases and confirmed the removal of the lesion in 90.6%, were indeterminate in 4.
