"Ultrasound demonstrates a smoothly circumscribed retrobulbar lesion with regular moderate to high internal echogenicity 3-4. No flow can be demonstrated on Doppler scanning 4."
"T1 C+ (Gd): slow mild arterial enhancment with progressive fill in and subsequent homogeneous or heterogeneous enhancment on delayed phases 5-7"
"According to ISSVA classification of vascular anomalies, these lesions are known as slow flow venous malformations 5. However, it is helpful in reports to include the word "cavernous" (i.e. cavernous venous malformation 5) as this term is ubiquitous in the literature and most familiar to many clinicians."
"For the more common intra-conal variety the differential includes 1-3:"
"Cavernous haemangiomas appear as a well-circumscribed, rounded or oval soft tissue density masses when they are small and become deformed due to their soft nature when getting larger; they are somewhat hypoattenuating compared to the muscle which gradually and incompletely fills in following the administration of contrast 1,2."
