[Ultrasonographic features in the preoperative diagnosis of XXXX ].

@entity5 @entity6887 @entity4134
OBJECTIVES: To review the characteristic ultrasound features of @entity6887 ( @entity6887 ) and its relationship to the clinical history in order to establish specific findings useful for the preoperative diagnosis. METHOD: An extensive review of the current literature was done on Medline via PubMed by using the following keywords: "primary @entity5 ", " @entity5 mass" and "ultrasound". RESULTS: @entity6887 corresponds to complex, sausage-shaped structures or @entity4134 . A thick and an irregular capsule are in favour of a @entity5 . Three-dimensional ultrasound is superior to 2D ultrasound for the detection of tubal wall irregularities such as papillary projections or pseudosepta who were suggestive of @entity5 and allows a better assessment of the extent of @entity5 infiltration through the capsule. Neovascularization with low resistance indices are typical of @entity5 . Three-dimensional power Doppler sonography acutely detected structural abnormalities of the @entity5 vessels which are randomly dispersed within the papillary projections. Intra-uterine collection and peritumoral fluid are often found but ascite could be also an indirect proof of peritoneal carcinosis. CONCLUSION: Sausage-shaped structures or @entity4134 associated with imaging findings such as papillary projections and neovascularization with low resistance indices are in favour of @entity6887 . A standardized terminology, high-frequency and 3D power Doppler could improve diagnostic performance by allowing a better assessment of tubal wall and chaotic vessels architecture of these @entity5 .
