Differential Diagnoses
Other Problems to Be Considered
Choroidal mass (tumor/metastasis)
Retinal telangiectasis
Retinal macroaneurysms
Workup
Laboratory Studies
- Vanillylmandelic acid levels in urine
Imaging Studies
- CT scan of brain with contrast
- MRI of brain (posterior fossa emphasis)
- Abdominal CT scan (to look for pheochromocytoma)
- Ophthalmic ultrasound
- Ocular color Doppler sonography
- In clinically diagnosed cases of angiomatosis retinae, applied color Doppler sonography is used to delineate the dilated, enlarged, and closely running feeder vessels on the retinal surface. The opposing directions of flow may indicate an artery or a vein. The angioma is not imaged because of a low-flow system. The above findings may be highly suggestive of angiomatosis retinae.
- Patients can be diagnosed clinically using ophthalmoscopy with its pathognomic appearance. The fundus shows the presence of an angioma in the temporal retinal periphery. Vessels will appear.
- A 7.5 MHz linear array transducer (Acuson 128XP) is used to examine the eyes. Real-time, gray-scale images and color Doppler images are obtained. Pulsed Doppler analysis also can be used to evaluate vascular dynamics.
- On application of color Doppler sonography, the feeder vessels appear to be a pair of dilated, tortuous blood vessels coursing to the angioma from the optic disc. The color image depicts the flow in these vessels to be in opposite directions. No flow can be appreciated in the angioma. These findings are of value in diagnosing this condition in cases where the visualization of the fundus is not possible with an ophthalmoscope due to opaque media, which may be a complication of the disease.
- The regression of the disease (angioma) can be followed and monitored by repeated studies, after treatment with various modalities (ie, cryotherapy, diathermy, irradiation, laser photocoagulation). It is common to see new angiomas appearing or growing in the region of treated angiomas.
- Color Doppler sonography provides a simultaneous morphologic and vascular image of the disease entity, enabling diagnosis and monitoring the effectiveness of treatment.
- Ocular color Doppler sonography is a safe, noninvasive, relatively inexpensive investigative modality in diagnostic ophthalmology.
- Optical coherence tomography (OCT), higher definition imaging systems with angiography, and neuroimaging advances have made von Hippel-Lindau disease more visible, thus allowing early interventions and effective outcomes.
