They include lesions associated with ectatic
lymphatics (lymphangioma-like and lymphangiectactic KS) and those that have an accumulation of superficial dermal oedema (bullous KS).
Keratoconus is an ectatic
corneal disorder characterized by progressive localized thinning and protrusion of the cornea, resulting in irregular astigmatism and decreased vision.
However, the characteristic features of PHAT, such as ectatic
hyalinized blood vessels and abundant hemosiderin deposition, are absent in superficial [CD34.
These data suggest that ethnic background significantly influences the incidence and the severity of keratoconus, since the Asian subjects present at a significantly younger age than Caucasian subjects and also appear to suffer from a more severe form of the ectatic
Magnetic resonance imaging of the pelvis demonstrated a dilated right ureter ectopically draining into a multiloculated cystic mass representing an ectatic
right seminal vesicle (Figure 2).
Advanced or progressive corneal ectatic
disease, for example, keratoconus
Fusiform aneurysm of basilar artery and ectatic
internal carotid arteries associated with glycogenosis type 2(Pompe's disease).
The cause of Meyerson phenomenon in PWS is not known despite several hypotheses, including a proinflammatory environment in the setting of ectatic
postcapillary vessels (2, 5, 7) or possible genetic mosaicism underlying nevi (5).
Histopathologic examination of skin lesions revealed vascular tissue with tortuous, blood- filled ectatic
vessels, lined by a single layer of endothelium, with surrounding thin connective tissue.
Although the histopathological examinations of ectatic
vessels have revealed similar findings as seen in atherosclerosis (30) it is not known exactly why connective tissue disorders (31, 32), infections (33), and Kawasaki (34) disease are related with CAE (35, 36).
Following dissection of the posterior peritoneum, the three ectatic
dural sacs were clearly visible.
Patients with diseased coronary artery segment (it could underestimate the coronary vessel diameter) ; Radio Contrast allergy (dangerous for patient); Ectatic
vessels (it might overestimate the real diameter of coronary artery);
