Enhanced Depth Imaging Optical Coherence Tomography Features of Choroidal Osteoma

Abstract

Analysis of eyes affected by choroidal osteoma revealed a characteristic sponge-like tumor appearance with the presence of multiple intralesional layers. The lesion showed a typical transparency with visibility of sclero-choroidal junction in all cases.

Enhanced depth imaging optical coherence tomography of choroidal osteoma with secondary neovascular membranes: report of two cases

“…The features described in the two cases mentioned above, compression of the choriocapillaris and disorganization of the medium and large vessel layers, are consistent with those of previous reports (4)(5)(6) . We noticed the sponge-like pattern previously reported (4)(5)(6) , but it was subtle.…”

“…These characteristics could represent varying degrees of calcification within the tumor because of the different phases of bone tissue formation. We noticed multiple hyperreflective dots scattered in the hyporeflective matrix creating a sponge-like appearance as previously reported (6) , but they were very subtle, especially under the CNV area. The sclerochoroidal junction was detected in both cases; however, in case 1, we were unable to detect it in all parts under the tumor because CNV had a fibrotic component that produced shadowing posterior to the membrane.…”

“…This finding is supported by histopathologic evidence from previous reports (10) . EDI-OCT of the osteoma revealed a typical reflectivity pattern in both cases with the presence of hyperreflective horizontal lamellar lines, which were described in other reports (5,6) . These characteristics could represent varying degrees of calcification within the tumor because of the different phases of bone tissue formation.…”

“…The choriocapillaris was thinned in both cases. Medium-caliber vessels (Sattler's layer) showed thinning and no visibility in both cases, whereas large-caliber vessels (Haller's layer) appeared as thinned rims of vessels between the tumor and sclerochoroidal junction, as was recently reported (6) . This finding is supported by histopathologic evidence from previous reports (10) .…”

Enhanced depth imaging and swept-source optical coherence tomography findings in choroidal osteoma: a case report

“…The spongy architecture in the calcified regions of the tumor as well as its Haversian canals, Volkmann canals, and cement lines have all been described in previous articles [9][10][11]13] and-save for Volkmann canals-can also be seen clearly in our case (Fig. 2a,c).…”
