Active thyroid surveillance effective, beneficial for older patients
A 58-year-old woman was diagnosed with ER-positive (Allred score 8) ILC in her right breast. Ultrasound and MRI found prominent lymph nodes in right axillary level I area, diagnosed as metastasis on ultrasound-guided fine-needle aspiration. F-18 FES-PET/CT showed a positive mass in right breast (white arrow; SUVmax, 5.6) and multiple F-18 FES–positive lymph nodes in right axillary level I, II, and II/III junction areas (red arrows; SUVmax, up to 12.2). In addition, a small F-18 FES-positive lymph node was observed in the right second internal mammary area (red circles; SUVmax, 1.8). However, biopsy could not be performed because it was too small and not visible on ultrasound; the clinician decided to include internal mammary lymph node in treatment field for adjuvant radiotherapy. The patient underwent lumpectomy with ALN dissection, with five metastases being identified in 13 lymph nodes dissected, and is scheduled to receive adjuvant chemotherapy, radiotherapy, and endocrine therapy.

Images depict biopsy-confirmed prostate cancer in a 56-year-old man. (A) Pretreatment axial T2-weighted fast spin-echo MRI scan and (B) apparent diffusion coefficient map acquired with a 3T scanner show the tumor in the left transition zone (arrows). (C) Intraoperative 1.5-T MRI scan shows the contoured rectal wall (red line), prostate margin (blue outline), and region of interest (orange outline). (D) Intraoperative MRI scan shows a focused ultrasound beam path (blue) overlaid on the treatment plan. The rectangular boxes show each sonication spot. (E) Thermal map obtained during treatment shows heat deposition color-coded in red and overlaid on the sonication spot. (F) Axial gadobutrol-enhanced MRI scan obtained immediately after treatment shows the devascularized ablated volume (arrows). (G) Corresponding T2-weighted fast spin-echo 3T MRI scan obtained at 24 months after ablation shows fibrosis and volume loss in the left transition zone (arrows). Findings from a biopsy showed scar tissue, negative for malignancy at the treatment site.
