Diagnosis: Retinal and choroidal detachment Retinal detachment may follow subretinal hemorrhage which may be a consequence of macular degeneration, trauma or persistent hyperplastic primary vitreous. In addition, lesions of the choroid may also induce retinal detachment. Most common of these are melanomas and choroidal hemangiomas. Hemorrhagic detachment of the choroid may be seen as a consequence of trauma, surgery or penetrating injury. On MR, retinal detachment with subretinal hemorrhage typically shows a lesion with relatively high signal on T1 below the retina which effaces the normal vitreous. Often there is infolding of the detached retina with the apex at the optic disk.
In this case, the lack of focal mass lesion makes neoplasm a less likely explanation for the retinal and choroidal detachment although it does not rule it out entirely. Eye exam failed to demonstrate any evidence of neoplasm. The enhancement associated with the choroid is presumably due to inflammation. Related Cases
