Imaging Features of Varix of the Vortex Vein Ampulla:A Small Case Series
نویسندگان
چکیده
Most of the blood from the iris, ciliary body and choroid is drained by the vortex vein lying behind the equator in each quandrant of the eye. About half of the vortex veins show dilatations of varying sizes and shapes which are referred to as the vortex vein ampullae [1]. Occasionally, an unusually large dilatation of the vortex vein ampulla can be found by fundus examination and sometimes mis-classified as visual threatening retinal choroidal diseases. Here we reviewed three cases of varix of the vortex vein ampulla which were found incidentally by B-scan ultrasonography and discussed their imaging features on various modalities, including ultrasonography, optical coherence tomography (OCT), Indocyanine green angiography (ICGA), and colour doppler flow imaging (CDFI).

Varix of the vortex vein ampulla: a small case series.
PURPOSE To report three cases of varix of the vortex vein ampulla. METHODS Observational small case series. During 2002, three patients were examined for suspected choroidal melanoma. In all cases, the lesions were located at the equator or the periphery. RESULTS The lesions became more prominent when the eyes were positioned in the direction of the lesion, and disappeared when firm pressur...

Fetal intraabdominal umbilical vein varix (FIUV) is focal dilatation of the intrabdominalumbilical vein of thefetus. It appears as a round or fusiform cystic structure in thefetal abdomen, which shows continuity with the umbilical vein ongrayscale andcolor Dopplerimaging.

متن کاملTrigeminal Neuralgia due to an Isolated Cerebral Varix: Case Report
Intracranial isolated varix is a very rare entity. Although it is usually asymptomatic, there are reports on symptomatic cases with hemorrhage or mass effect that mostly relate to arteriovenous fistulas or arteriovenous malformations. We present an extremely rare case of trigeminal neuralgia caused by an isolated varix. A 55-year-old woman had been experiencing right trigeminal neuralgia for 3 ...

The features of Hypertrophic pulmunary osteoarthropathy (HPOA) on radionuclide bone scintigraphy have been well described in case reports and small series of patients. The aim of this study was to investigate prospectively the prevalence and distribution of HPOA in a large series of patients with carcinoma of the lung. Two hundred and eleven patients aged 31-89 years (average age 66 years...
متن کاملA complex pulmonary vein varix -- diagnosis with ECG gated MDCT, MRI and invasive pulmonary angiography.
A case of an asymptomatic 32-year-old male with a complex congenital pulmonary vein varix is reported herein. Chest X-ray incidentally revealed a tubular opacity passing from the periphery of the left lingula to the mediastinum. ECG gated multidetector computed tomography showed the opacity to be a vessel emptying into the left atrium via the left superior pulmonary vein. In addition, a second ...
