Purpose: To evaluate the clinical and imaging outcome of aneurysmal bone cysts (ABCs) in children using percutaneous cryoablation as the sole treatment.
Materials And Methods: This retrospective study included 7 children with a mean age of 8.7 years (range, 3.0-11.9 years) who underwent at least 1 cryoablation for ABC. Cryoablation needles were placed and guided by computed tomography (CT). Imaging follow-up and clinical examination were performed by radiography 1 and 6 months after the procedure and magnetic resonance (MR) imaging was performed 3 and 12 months after the procedure. Additional cryoablation was performed in case of MR imaging-detected recurrence. Data were analyzed by anatomical location, measurement of lesion volume, numbers of intralesional cysts, grade of mineralization (5-point Likert scale), pain (0 [none] to 4 [severe]), and grade of fluid-fluid levels (FFLs; 4-point Likert scale).
Results: Fourteen cryoablations were performed. Patients showed volume reduction, with 1 showing a complete response and 6 showing partial response. Following treatment, there was a substantial reduction in lesion volume compared with baseline, leading to a mean volume decrease of 81.9% (range, 66.8%-100%). The grade of mineralization (3.2 [SD ± 1.2] after therapy vs 1.1 [SD ± 0.3] at baseline), grade of FFL (1.6 [SD ± 0.5] after therapy vs 3.4 [SD ± 1.1] at baseline), and pain (0.29 [SD ± 0.4] after therapy vs 1.86 [SD ± 0.7] at baseline) significantly improved after therapy (all P < .05). One severe adverse event occurred.
Conclusions: Cryoablation is an effective treatment option for ABC in children. Further research is needed to compare it with other techniques.

Background And Objectives: The middle fossa approaches are tremendously versatile for treating small vestibular schwannomas, selected petroclival meningiomas, midbasilar trunk aneurysms, and lesions of the petrous bone. Our aim was to localize the internal acoustic canal and safely drill the petrous apex with these approaches. This study demonstrates a new method to locate the internal acoustic canal during surgery in the middle fossa.

Background: Preoperative estimation of intraoperative blood loss is essential for its management and literature is lacking with respect to factors influencing blood loss in aneurysmal bone cysts (ABC) surgery. The purpose of this study is to identify risk factors and predictors for blood loss in ABC surgery.
Methods: An IRB-approved retrospective review was performed from 2011 to 2021 at a pediatric tertiary care center.

Background: The safety of endovascular treatment, such as thoracic endovascular aortic repair (TEVAR), for a descending thoracic aortic aneurysm has been well-established, with a reported low postoperative mortality rate but higher incidences of long-term complications such as endo-leakage, device failure, and aneurysm-related death. Based on this, we report the first case of massive thoracic vertebral body erosion due to a perianeurysmal outpouching lesion after TEVAR.
Case Presentation: A 77-year-old female with a history of TEVAR due to descending thoracic aortic arch aneurysm 4 years ago was referred from the cardiovascular clinic to the spine center.

Ulnar artery aneurysms are extremely rare and are mainly associated with hypothenar hammer syndrome, an ischemic disorder of the hand resulting from mechanical and repetitive trauma to the hypothenar region. The ulnar artery is hit against the hook of the hamate bone, causing damage to the vessel wall and leading to occlusion or formation of an aneurysm. We describe the case of a truck driver who underwent resection of an ulnar artery aneurysm in the right hand and reconstruction using end-to-end anastomosis with no complications or recurrence.

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.
