Fibroid of cervix in 19 week pregnancy:

These two ultrasound video clips show a large fibroid involving the lower uterine segment and upper cervix in a 19 week pregnancy. The fetal head is seen towards the left with the urinary bladder seen towards the right of the video. The mass was poorly vascular and affected the anterior wall of the cervix. The fetus showed normal body movements and appeared healthy.
See: http://www.ultrasound-images.com/uterus.htm for more similar/ different types of fibroids of the uterus.
(fet= fetus; fibr= fibroid of the cervix; bl= urinary bladder). This video shows a sagittal section of the uterus and cervix.

3-D ultrasound image of appendix of testis:

B- mode ultrasound image shows the appendix of the testis with surrounding tunica vaginal fluid (a small hydrocele). The testicular appendage appendage is seen projecting into the fluid.















3- Dimensional ultrasound image shows the appendix testis (A) between the head of epididymis and testis. (Images are courtesy of Ravi Kadasne, MD, UAE).

3D ultrasound- an interesting perspective:

These 3 dimensional ultrasound images show various pathologies of the urinary bladder, providing a whole new "dimension" to sonographic imaging.

3- D ultrasound image of ureterocele:
The Rt. ureterocele is seen as a small sac bulging in from the posterior wall of the bladder.















3-D ultrasound image of bladder diverticulum:
A small right sided vesical diverticulum. (UB= urinary bladder)














Vesical calculus:
This 3-D ultrasound image of a vesical calculus shows that 3-D imaging must be used in conjunction with 2-D B-mode imaging to identify pathology. This bladder calculus is difficult to distinguish from (see topmost image) ureterocele purely on 3-D ultrasound. Perhaps a cross sectional image would show the internal structure better.

Non obstructive Vesico-ureteric junction calculus

Do ureteric calculi necessarily produce obstruction to the passage of urine in the ureters? These ultrasound and color Doppler images study just this fact..
Observe the ultrasound image of the urinary bladder below: a right vesico-ureteric junction calculus is clearly visible. The patient had severe right ureteral colic too. The right VUJ calculus measures 6 mm. in size.















Color Doppler image shows almost normal right ureteral jet, despite the calculus at the ureteric orifice.















Yet another Doppler image shows another jet emanating from the right ureteric orifice.















The right kidney appears normal- no evidence of obstructive changes here.














The conclusion: small ureteric calculi can produce almost no obstructive changes despite being located at the narrow ureteral orifice into the bladder. But repeated studies by me show this is an exception, rather than the rule. Most ureteral calculi produce partial or major obstruction in the affected ureter.

Sonographic visualization of a large ureteric calculus

The right ureter appears moderately dilated till its lower third (hydroureter) with the ureteral calculus lodged at the junction between the middle and lower thirds. This patient was an elderly female with abdominal obesity. This made ultrasound imaging of the ureteric calculus extremely difficult. However, probe compression over the path of the right ureter helped displace bowel loops and brought the entire ureter into view.














The right kidney shows evidence of moderate hydronephrosis,- the result of long standing ureteric obstruction. (See ultrasound image below):














This patient also had a couple of right renal calculi (only one is visualized in this ultrasound image- below).

Cystic tumors of the ovary:

A serous cystadenoma of the ovary is seldom so well manifested as in this case. This huge cystic lesion had this solitary septum with a vessel well seen on Power Doppler. See more ultrasound images of this case at:
http://www.ultrasound-images.com/ovarian-masses.htm
Here you will find a sonographic pictorial review a variety of cystic masses (cysts) of the ovaries. Among them are mucinous cystadenoma and cystadenocarcinoma and calcific masses like dermoid cyst.

there are interesting ultrasound pictures of functional cysts of the ovaries, hemorrhagic ovarian cysts and the bane of modern women: chocolate cyst or endometrioma of ovary.
