Unexpected presentation: metastatic adenoid cystic carcinoma (AdCC) of the breast masquerading as a large cystic-solid renal mass.

Adenoid cystic carcinoma (AdCC) of the breast is a rare histological subtype of breast cancer, which usually has a low propensity for metastasis and is associated with a good prognosis. AdCC metastasis to the kidney is rare, with only 29 cases reported in the literature. We report a case of a woman in her 60s with multiple right-sided large cystic-solid renal lesions after a recent diagnosis of marginal zone B-cell lymphoma.

Influence of preoperative embolisation on resection of brain arteriovenous malformations: cohort study.

Purpose: Preoperative endovascular embolisation is a widely used adjunct for the surgical treatment of brain arteriovenous malformations (AVMs). However, whether this improves completeness of AVM resection is unknown, as previous analyses have not adjusted for potential confounding factors. We aimed to determine if preoperative endovascular embolisation was associated with increased rate of complete AVM resection at first surgery, following adjustment for Spetzler-Martin grade items.

Prasugrel Single Antiplatelet Therapy versus Aspirin and Clopidogrel Dual Antiplatelet Therapy for Flow Diverter Treatment for Cerebral Aneurysms: A Retrospective Multicenter Study.

Background And Purpose: The optimal antiplatelet regimen after flow diverter treatment of cerebral aneurysms is still a matter of debate. A single antiplatelet therapy might be advantageous in determined clinical scenarios. This study evaluated the efficacy and safety of prasugrel single antiplatelet therapy versus aspirin and clopidogrel dual antiplatelet therapy.

High variability in physician estimations of flow-diverting stent deployment versus PreSize Neurovascular software simulation: a comparison study.

Background: Physician variablity in preoperative planning of endovascular implant deployment and associated inaccuracies have not been documented. This study aimed to quantify the variability in accuracy of physician flow diverter (FD) planning and directly compares it with PreSize Neurovascular (Oxford Heartbeat Ltd) software simulations.

Methods: Eight experienced neurointerventionalists (NIs), blinded to procedural details, were provided with preoperative 3D rotational angiography (3D-RA) volumetric data along with images annotated with the distal landing location of a deployed Surpass Evolve (Stryker Neurovascular) FD from 51 patient cases.
