Abstract:
Objective To describe CT and MRI imaging findings of retinal hamartomas with tuberous sclerosis and evaluate their clinical value. Design Retrospective case series. Participants 7 patients of tuberous sclerosis complex (TSC) who have ocular lesions found with CT and MRI examination. Methods 7 patients with tuberous sclerosis were diagnosed by clinical data and head CT. The size, morphology, density and enhancing situation of the retinal lesions were observed with CT and MR.I, as while as with direct or indi-rect fundoscopy. Main Outcome Measures CT and MRI features of ocular lesions. Results 7 cases displayed intraeranial calcification and/or non-calcified tubercles, situating in subendyrna (7 cases, accounting for 100%) by head CT. Orbital CT and MRI showed 4 cases (57.1%) of flat retinal hamartomas 3 cases (42.9%) 9f retinal lobular and nodular hamartomas, 2 cases(28.6%) scattered calcification patches in hamartoma, and 2 cases (28.6%) of nanophthalmos. The lesions displayed unenhancement on contrast-enhanced MR images in 7 cases(100%) . There was 1 case (14.3%) of progressive retinal astrocytic hamartoma. Conclusion The examination of CT and MRI may find the bigger retinal hamartomas, which can play a very important role at the diagnosis with the help of whole brain examination. For progressive retinal nstrocytic hamartoma,systemic evaluation with CT and MRI can provide evidence for choosing appropriate thera-pies. (Ophthalmol CHN, 2009, 18: 257-260)
