  • The clinico-pathological analysis of choroidal metastatic carcinom aarising from lung carcinoma

    Objective To observe the clinical and pathological characteristics of choroidal metastatic carcinoma from lung carcinoma.Methods The clinical and pathological data of 6 patients with choroidal metastatic carcinoma from lung carcinima were analysed retrospectively.Results All the 6 patients had severe visual impairment, including 3 with severe ophthalmalgia. Flat neoplasm were seen in the posterior pole of the eyes in all the 6 patients and retinal detachment were found in 5 patients. Fundus fluorescein angiography (FFA) examination had been performed on 1 patient and blocked fluorescence and hyperfluorescence were seen in the lesion with pinpoint fluorescein leakage loop around it. CT examination had been performed on 3 patients and the shadow of flat homogenous tumor was seen. MRI examination had been performed on 1 patient and high signal intensit ies on T1W and low signal intensities on T2W were found. In all the 6 patients with primary lung carcinoma, 5 were diagnosed with adenocarcinoma and 1 with cellule carcinoma through pathological examination, and 5 patients were diagnosed with choroidal metastatic carcinoma from adenocarcinoma and 1 with choroidal metastatic carcinoma from cellule carcinoma through pathological examination.Conclusion Rapid visual acuity decrease, severe ophthalmalgia, flat neoplasm in ocular fundus and secondary retinal detachment are the main clinical characteristics of the choroidal metastatic carcinoma from lung carcinoma. Most histopathologica l manifestations of the metastatic carcinoma like that of the primary focus, and adenocarninoma is the most common histoclassification. (Chin J Ocul Fundus Dis,2003,19:333-404)

  • Fundus angiography in metastatic carcinomas of choroid

    Objective To evaluate the characteristics of two angiographic manifestation of ocular fundus in choroidal metastatic carcinomas. Methods Fundus fluoresein angiography (FFA) and indocyanine green angiography (ICGA) were performed on 17 patients (24 eyes) with choroidal metastatic carcinomas, and the characteristics of these two kinds of angiograms were analyzed and compared each other. Results According to various clinical features, e.g., locations of metastatic tumor in ocular fundus, disease course, and different kinds of original malignancy, the findings of ocular fundus were divided into (1) Isolation type: FFA showed pinpoint and mottled leaks against hypofluorescence background, increased and confluent fluoresecence in later stage. ICGA showed the similar images as in FFA, except later appearance of leaks and the choroidal vesseles could be seen beneath the thin metastatic tumor mass.(2) Diffusion type: Tumors showed hypofluorescence in early stage and uneven ill-defined hyperfluorescence both in FFA and in ICGA. (3) Small metastatic carcinomas: Hypofluorescence in early stage and mild mottled hyperfluorescence were found in FFA as well as in ICGA. Conclusion Both FFA and ICGA are helpful in the diagnosis of choroidal metastatic tumors and ICGA may be conducive if there are some troubles in diagnosing the tumors with FFA.
