Choroidal metastases as initial manifestation of a papillary thyroid carcinoma: A case report. / Metástasis coroidea como primera manifestación de carcinoma papilar de tiroides: a propósito de un caso.

The case is presented of 78 year-old who consulted due to decreased visual acuity in right eye for several months. Indirect ophthalmoscopy revealed an orange-yellow coloured choroidal mass at the posterior pole, without retinal detachment. Computed tomography showed a thyroid mass in the isthmus, as well as multiple pulmonary nodules and metastatic foci. The findings of transbronchial lung biopsy were compatible with metastatic dissemination. Fine-needle aspiration biopsy of thyroid nodule was diagnostic for a with columnar cell variant of papillary thyroid cancer. Positron emission tomography confirmed papillary thyroid carcinoma. The patient underwent total thyroidectomy and radioactive iodine therapy.

Management of the neovascular choroidal membrane secondary to ocular toxoplasmosis. / Manejo de la membrana neovascular coroidea secundaria a toxoplasmosis ocular.

A 12-year-old patient diagnosed with congenital toxoplasmosis, with no systemic treatment at the time, who presented with a decreased visual acuity (VA) in his left eye (LE). On examination, VA in the LE was 0.05 and the fundus examination revealed a focus of chorioretinitis adjacent to a pigmented macular scar, as well as a large associated subretinal haemorrhage. After confirming the diagnosis of choroidal neovascular membrane secondary to ocular toxoplasmosis, treatment was started with systemic anti-toxoplasmosis drugs and two anti-VEGF intravitreal injections separated by one month. Finally, the patients had a VA in LE of 0.4, with reabsorption of the haemorrhage, leaving an inactive pigmented macular scar. The use of anti-VEGF intravitreal injections in cases of ocular toxoplasmosis has been associated with a reactivation of old lesions, so the prophylactic use of oral anti-toxoplasmosis drugs is recommended in these cases.
