Echogenic foci representing calcification, cartilage, immature bone and fibrosis are commonly seen [Fig. 5]. Cysts are also a common feature and depending on the contents of the cysts i.e. serous, mucoid or keratinous fluid, it may present as anechoic or complex structure [Fig. 6]. [citation needed]
The standard representation is brighter color for higher echogenicity, giving the almost anechoic fluid an almost black appearance. Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing ...
Acorn cyst sign is a radiologic sign indicating the presence of a benign uncomplicated cyst in ultrasound examinations of the breast. [1] It consists of a deep anechoic fluid portion resembling an acorn, and a superficial echogenic layer resembling an acorn cap. This sign is helpful for radiologists to differentiate a benign uncomplicated cyst ...
Epididymal cyst is a harmless sac in the testicles filled with fluid. [2] The most frequent clinical presentation occurs when a routine physical examination yields an unexpected finding, which is then confirmed by scrotal ultrasonography . [ 1 ]
Endometrioma (also called chocolate cyst) is the presence of tissue similar to, but distinct from, the endometrium in and sometimes on the ovary. It is the most common form of endometriosis . [ 1 ] Endometrioma is found in 17–44% patients with endometriosis.
Cysts cause posterior enhancement as a consequence of reduced attenuation of the ultrasound within the cyst fluid (Figure 5). The simple cyst is a benign lesion, which does not require further evaluation. [1] Complex cysts can have membranes dividing the fluid-filled center with internal echoes, calcifications or irregular thickened walls.
Peritoneal inclusion cysts are commonly visualized on ultrasonography as a spider-web-like pattern. A normal-looking ovary is encircled by a big, irregular or oval, echolucent cyst with fine internal septations. The ovary is frequently located in the middle of the inclusion cyst or on its lateral aspect, appearing to be dangling inside the cyst ...
Ovarian cysts are usually diagnosed by pelvic ultrasound, CT scan, or MRI, and correlated with clinical presentation and endocrinologic tests as appropriate. [15] Ultrasound is the most important imaging modality, as abnormalities seen in a CT scan sometimes prove to be normal in ultrasound.
