Intracranial empyema complicating sinusitis in childhood: Epidemiology, imaging findings and outcome.

Background: To describe clinical presentations of intracranial sinusitis complications in childhood, their pitfalls and imaging findings.

Materiel And Methods: This retrospective IRB-approved single-center study included infants diagnosed with sinusitis and empyema and/or other intracranial complications who underwent imaging between September 2008 and September 2019. Three radiologists individually reviewed clinical charts and imaging findings, including sinusitis complications and at-risk anatomical variations.

Magnetic resonance imaging diagnosis of subependymal giant cell astrocytomas in follow-up of children with tuberous sclerosis complex: should we always use contrast enhancement?

Background: Subependymal giant cell astrocytomas (SEGAs) arise in 10-26% of tuberous sclerosis complex (TSC) patients. SEGAs cause obstructive hydrocephalus and increase morbi-mortality. It is recommended that TSC patients be followed with contrast enhanced magnetic resonance imaging (CE-MRI), but repetitive use of gadolinium-based contrast-agents (GBCAs) may cause organ deposits.

Percutaneous cryoablation of symptomatic localized venous malformations: preliminary short-term results.

Short-term outcomes after percutaneous image-guided cryoablation of symptomatic venous malformations in four consecutive patients (mean age, 42.5 y) are reported. Two patients had local recurrences after previous treatment.

Salvage CT-guided transgluteal cryoablation for locally recurrent prostate cancer: initial experiences.

Technical feasibility of a computed tomography (CT)-guided transgluteal approach for salvage cryoablation of inoperable locally recurrent prostate cancer was evaluated retrospectively. Five procedures were performed under general anesthesia in five patients previously treated with radiation therapy. Median age was 64 years, and average pretreatment prostate-specific antigen (PSA) level was 2.
