Introduction
Very rare benign vascular tumours, composed of vessels. Usually dome shaped with a red-orange mass, commonly at the posterior pole.
- Typically associated with surface cystoid retinal degeneration
- RPE degeneration
- Long-term serous retinal detachment and chronic macular oedema.
Differentials include:
- Choroidal metastasis
- Amelanotic choroidal melanoma
- Choroidal Osteoma
- CSCR
- Serous retinal detachment
- Retinoblastoma
Dead Giveaways
Circumscribed Choroidal Haemangioma
Reddish-orange, round to oval choroidal tumour; mostly asymptomatic and incidental
~3-7mm diameter and 1-3mm thick
It is usually located ~2DD from the optic disc, fovea or both at their posterior margins
RPE overlying the lesions commonly degenerates
Frequently associated with serous retinal detachment and chronic macula oedema.
CSCR is a major differential
Diffuse Choroidal Haemangioma
In 30-50% of patients with Sturge-Weber Syndrome, and is unilateral and ipsilateral
Ill defined borders that spread in posterior choroid, and the fundus is more saturated red
Example of diffuse
diagnostic features
Imaging Note:
B-scan ultrasound shows haemangioma being solid, similar to surrounding choroid on A-scan.
There is high internal reflectivity, whereas a choroidal melanoma is acoustically hollow with medium to low internal reflectivity
Non-hollow Angiography reveals leaky vessels with fluorescein and ICG
Shows the highly leaky vessels
