Iatrogenic Axillary Pseudoaneurysm Caused by Ultrasound-guided, Vacuum-assisted Biopsy of the Axillary Lymph Node: A Case Report
Arterial pseudoaneurysms are contained ruptures of the arterial wall that require prompt intervention. Iatrogenic pseudoaneurysms may result from various diagnostic and therapeutic procedures. Iatrogenic axillary pseudoaneurysms are quite rare, with few reported cases in the literature. We report a case of a 45-year-old woman who sustained an axillary pseudoaneurysm after an ultrasound-guided, vacuum-assisted biopsy of the axillary lymph node. An arteriovenous fistula developed concomitantly. Despite two image-guided treatments, thrombin injection and endovascular coil embolization, the pseudoaneurysm had persistent flow and was ultimately surgically resected at the time when the patient underwent mastectomy for breast cancer

Accuracy of whole-body HDP SPECT/CT, FDG PET/CT, and their combination for detecting bone metastases in breast cancer:an intra-personal comparison
New generation SPECT/CT scanners allow rapid whole-body imaging, and potentially facilitate significantly improved diagnostic accuracy. Thus, the aim of this study was to compare the diagnostic accuracy of whole-body Tc-99m-HDP SPECT/CT, F-18-FDG PET/CT, and their combination for detecting bone metastases in breast cancer. Women with biopsy-proven breast cancer that were referred for whole-body SPECT/CT and FDG PET/CT were consecutively included in this retrospective study. Two blinded readers independently interpreted all scans. In a per-patient analysis, the diagnostic performances of whole-body SPECT/CT, FDG PET/CT, and their combination were compared using receiver operating characteristic (ROC) analysis. In a per-lesion analysis, the performances were compared using figures of merit (FoM) differences in Jackknife alternative free-response ROC analysis, which considers the location information. Follow-up served as reference standard. Overall, 25 consecutive women (median age: 55; range 38-82) with 117 lesions were included. The median follow-up was 21 months (2-46 months). The per-patient analysis revealed no significant differences in diagnostic performance (P = 0.16), while the per-lesion analysis revealed a diagnostic superiority of whole-body SPECT/CT over FDG PET/CT (P = 0.004). Specifically, the PET/CT FoM was significantly lower than the SPECT/CT FoM (FoM difference = -0.11, 95% CI [-0.21; -0.02], P = 0.021). No significant difference was observed between SPECT/CT and the combination of SPECT/CT and PET/CT. The per-lesion analysis suggest that SPECT/CT has a higher diagnostic accuracy than FDG PET/CT for the detection of bone metastases. Thus, SPECT/CT may be a useful adjunct to FDG PET/CT for staging of breast cancer patients
