Surgery of long bone metastases is associated with a significant risk of perioperative blood loss, which may necessitate blood transfusion.Successful embolization (> 70% obliteration of vascularity) can be achieved in 36-75% of cases.The reported rate of embolization-related complications is 0-9%.Three out of six level III evidence studies showed a reduction in perioperative blood loss and/or blood transfusion requirement after preoperative embolization of renal cell carcinoma metastasis in long bones; three out of six studies did not.One level III evidence study did not show a reduction in perioperative blood loss and/or transfusion requirement after preoperative embolization of hepatocellular carcinoma metastases in long bones.There were no studies found that support preoperative embolization of thyroid metastases or other frequent long bone metastases (e.g. mamma carcinoma, lung carcinoma, or prostate carcinoma).The clinical level of evidence of the studies found is low and randomized studies taking into account primary tumour, location of metastases and type of surgery are therefore desired.

Pulmonary sequestration is a rare congenital anomaly, characterized by aberrant lung tissue supplied by an aberrant systemic artery or arteries coursing within the inferior pulmonary ligament. The intralobar variety is the most frequent form. Clinical presentation may include recurrent haemoptysis and infection.

J Comput Assist Tomogr

From the Department of Diagnostic Radiology, Faculty of Life Sciences, Kumamoto University, Kumamoto.
Objective: Discriminating between hemorrhage and iodine extravasation can pose challenges in conventional computed tomography (CCT) images following preoperative embolization for meningioma. This study aimed to assess the efficacy of dual-energy computed tomography (DECT) in differentiating hemorrhage from iodine extravasation after preoperative embolization for meningioma.
Methods: Twenty-one consecutive meningioma patients who underwent CCT before and DECT immediately after preoperative embolization were included in this study.

Article Synopsis
- Pulmonary sequestration is a rare congenital lung issue where abnormal lung tissue is supplied by a wrong artery, most commonly seen in the intralobar form.
- Patients often experience symptoms like recurrent coughing up blood and lung infections.
- Surgical treatment involves carefully removing the affected tissue while protecting healthy lung, with techniques to minimize the risk of bleeding from the abnormal arteries during the procedure.
Fibrous dysplasia coexisting with aneurysmal bone cyst in the skull base: A case report.
Radiol Case Rep
March 2025
Pediatric Radiology, HOMI-Fundación Hospital Pediátrico la Misericordia, Bogotá, Colombia.
The coexistence of fibrous dysplasia and aneurysmal bone cyst in the craniofacial region is extremely rare. This article presents a unique case involving the skull base, diagnosed using computed tomography and magnetic resonance. Imaging revealed a characteristic expansile mass with a ground-glass appearance alongside cystic areas exhibiting fluid-fluid levels, indicative of fibrous dysplasia and aneurysmal bone cyst.
