Pathology
In 1976, Witschel and Font [3] described the clinicopath-
ologic features of 45 eyes with circumscribed choroidal
hemangioma that came to enucleation and were evalu-
ated at the Armed Forces Institute of Pathology. They
described solitary hemangioma as a circumscribed tumor
with a sharply demarcated margin, causing compression
of adjacent choroidal melanocytes and lamellae. No pro-
liferation of endothelial cells was observed in these tu-
mors. Alterations of overlying RPE were common, rang-
ing from atrophy and local proliferation to severe fibrous
transformation or ossification. Almost all lesions showed
degenerative changes of the overlying retina, including
loss of photoreceptors, cystoid degeneration, gliosis, and
invasion by RPE cells.

Ancillary studies
Choroidal hemangioma shows characteristic features on
ultrasonography, fluorescein angiography, indocyanine
green angiography, and magnetic resonance imaging
(Table 2). With ultrasonography, the hemangioma is
acoustically solid on B-scan, and the echogenic character
is generally similar to that of the surrounding choroid
(Fig. 2A). On A-scan ultrasonography, high internal re-
flectivity is characteristic (Fig. 2B). Intrinsic vascular pul-
sation is generally not a feature of this tumor [2••,13].         (A) A-scan ultrasound shows the characteristic high internal reflectivity of

Circumscribed choroidal hemangioma usually appears as a discrete, round, orange-red tumor, similar in appear- ance to the adjacent surrounding choroid (Fig. 1). A pig- mented rim, possibly secondary to compression of adja- cent choroid or elevation of the retinal pigment epithelium (RPE), often surrounds the tumor. Almost all cases occur posterior to the equator, usually near and temporal to the optic disc [3]. Clumps of pigment, prob- ably secondary to hyperplasia of overlying RPE, are not uncommon [2••]. Retinal or subretinal exudation is not a common feature of choroidal hemangiomas and was re- ported in only 7% of patients in one series [4]. Mushroom appearance is exceedingly rare [2••]. 142
  • 2. Circumscribed choroidal hemangioma Mashayekhi and Shields 143 Figure 1. Clinical appearance of circumscribed choroidal the Oncology Service at Wills Eye Hospital, the clinical hemangioma diagnosis of choroidal hemangioma was accurately sus- pected before referral for only 29% of the patients, and 14% were referred without any specific diagnosis (Table 1) [2••]. Several reasons may account for this situation: (1) The ophthalmoscopic appearance of choroidal hem- angioma may be almost indistinguishable from the normal adjacent choroid. Failure to detect the tu- mor may account for referral diagnoses such as ret- robulbar optic neuritis, high hypermetropia, or age- related macular degeneration. (2) The presence of an overlying exudative retinal de- tachment can obscure the underlying choroidal de- tails and may make the tumor even more obscure. This situation can lead to an erroneous diagnosis of retinal detachment, central serous chorioretinopa- thy, or macular edema. (3) The funduscopic appearance of circumscribed cho- roidal hemangioma may simulate other benign or malignant conditions of the fundus. In the series from Wills Eye Hospital, 38% of patients were re- ferred with the diagnosis of an intraocular malig- nancy, most commonly amelanotic choroidal mela- noma or choroidal metastasis (Table 1) [2••]. Several ophthalmoscopic features may help differentiate choroidal hemangiomas from simulating lesions. Choroi- dal hemangiomas have a distinctive orange-red color similar to the surrounding choroid, whereas amelanotic melanomas are a more yellow-tan color, often with subtle intrinsic pigment and visible overlying drusen. Clinically evident drusen are rare overlying choroidal hemangioma and were detected in only 2% of patients in one series [2••]. In contrast to choroidal melanomas, choroidal hemangiomas almost never attain a mushroom-shaped appearance [2••]. Choroidal metastasis appears as a creamy yellow plateau or elevated mass and in contrast to choroidal hemangioma, which is almost always solitary and unilateral, may commonly be multifocal or bilateral. However, three specific choroidal metastases—from renal cell carcinoma, thyroid carcinoma, and carcinoid (A) Wide-angle fundus photograph of circumscribed choroidal hemangioma with Table 1.

Spontaneous reabsorption of sub- retinal fluid can occur in some patients following deliv- ery [8•,11]. Pathology In 1976, Witschel and Font [3] described the clinicopath- ologic features of 45 eyes with circumscribed choroidal hemangioma that came to enucleation and were evalu- ated at the Armed Forces Institute of Pathology. They described solitary hemangioma as a circumscribed tumor with a sharply demarcated margin, causing compression of adjacent choroidal melanocytes and lamellae. No pro- liferation of endothelial cells was observed in these tu- mors. Alterations of overlying RPE were common, rang- ing from atrophy and local proliferation to severe fibrous transformation or ossification. Almost all lesions showed degenerative changes of the overlying retina, including loss of photoreceptors, cystoid degeneration, gliosis, and invasion by RPE cells. Ancillary studies Choroidal hemangioma shows characteristic features on ultrasonography, fluorescein angiography, indocyanine green angiography, and magnetic resonance imaging (Table 2). With ultrasonography, the hemangioma is acoustically solid on B-scan, and the echogenic character is generally similar to that of the surrounding choroid (Fig. 2A). On A-scan ultrasonography, high internal re- flectivity is characteristic (Fig. 2B). Intrinsic vascular pul- sation is generally not a feature of this tumor [2••,13]. (A) A-scan ultrasound shows the characteristic high internal reflectivity of These features would be unlikely with choroidal mela- circumscribed choroidal hemangioma.

Marked attenuation of the light signal occurs after passing through the neurosensory retina and RPE, limiting the usefulness of this technique for direct evaluation of choroidal tumors. Treatment The goal for management of choroidal hemangioma is preservation or improvement of visual acuity by stimu- lating absorption of subretinal fluid and resolution of macular edema before irreversible retinal or RPE alter- ations have occurred. Re-treatment of residual extrafo- veal tumors without subretinal fluid is not necessary. It is not yet clear whether incomplete flattening of hemangi- omas predisposes to later recurrence of subretinal fluid. A secondary goal, in more advanced cases, is prevention of neovascular glaucoma from long-standing, extensive, secondary retinal detachment [11]. Long delay between onset of symptoms and onset of treatment may be associated with a worse visual outcome [2••,17,18]. In the Wills Eye Hospital series, poor final visual acuity ( 20/200) was more common in patients treated after 6 months of symptoms (72%) compared with those treated within 6 months of symptoms (42%) [2••]. In the same study, initial visual acuity was found to be a good predictor of visual outcome [2••], and pa- tients with poor visual acuity at presentation, especially if associated with chronic retinal and RPE changes, should be warned of long-term poor visual acuity. Loca- tion of the hemangioma relative to fovea has also been identified as an important predictor of final visual acuity. In a smaller series reported from Wills Eye Hospital, poor visual acuity of 20/200 was obtained in 69% of pa- tients with subfoveal hemangioma, in 47% of those with parafoveal tumors, and in 38% of patients with an extra- foveal tumor [4].

All eyes responded favorably with regression in tumor thick- ness, resolution of subretinal fluid, and improvement of visual acuity. No radiation side effects were noted during the follow-up period (range, 0.4–8.8 years). Similar good results have been obtained with proton beam radio- therapy, providing resolution of subretinal fluid in 67 to 100% of patients [28–30]. It has been claimed that proton beam-induced papillopathy and maculopathy can be avoided if a low dose of 18 Gy is delivered [29,30]. Photodynamic therapy is the most recent modality used for the management of circumscribed choroidal heman- giomas. PDT using benzoporphyrin-MA (verteporfin) has been previously shown to cause immediate disinte- gration of endothelial membranes and vascular thrombo- sis, leading to complete necrosis of experimental choroi- dal melanoma in a rabbit model [31]. In contrast to laser photocoagulation and transpupillary thermotherapy, the success of PDT does not depend on a thermal effect, allowing a selective occlusion of vascular lesions with minimal damage to the adjacent retina [32]. During the past 2 years, 5 small case series have been (A) On T1-weighted image with gadolinium enhancement, the hemangioma is published on circumscribed choroidal hemangioma distinctly hyperintense compared with the vitreous.
