This is the peripheral component of the complex mass that was seen in the right adnexa. It appears to be an enlarged and heterogeneous right ovary with peripherally

displaced follicles - this is classical for torsion.

This is a normal appearance of the right ovary .

Color Doppler demonstrates normal flow within the right ovary

The left ovary is enlarged, has an abnormal gray scale appearance and appears heterogeneous .

There is scant internal and peripheral flow .

Gray-scale sagittal image reveals right ovary to be enlarged (7 cm) with peripheral follicles and areas of increased echogenicity

Color Doppler demonstrates no flow within the ovary .

Power Doppler confirms almost no flow in the ovary .

OVARIAN TORSION

OVARIAN TOSION

TORSION

There is a complex mass seen in the right adnexa. The right ovary is not seen separate from the

Spectral analysis demonstrates a normal arterial waveform. The venous waveform however, could not be obtained, implying that the venous supply is probably compromised .

The complex heterogeneous mass is again noted in the right adnexa. It is predominantly hypoechoic with a few cystic areas within the mass.

The contralateral left ovary appears normal and shows prominent follicles within .

This is the peripheral component of the complex mass that was seen in the right adnexa. It appears to be an enlarged and heterogeneous right ovary with peripherally displaced follicles - this is classical for torsion.

Case Isolated left tubal torsion

The uterus with the normal endometrial stripe is notedIsolated left tubal torsion

There is a hypoechoic structure seen in the left adnexa that appears cystic, contains low-level internal echoes,some debri and thin septae. The mass shows good posterior

enhancement. Isolated left tubal torsion

The cystic structure is noted again and shows very thin, barely perceptible walls. The patient had probe tenderness while scanning

this structure Isolated left tubal torsion

The cystic structure is noted again displaying the homogeneous low-level internal echoes Isolated left tubal torsion

Case Left ovarian torsion

This is a normal appearance of the right ovary .

Color Doppler demonstrates normal flow within the right ovary Left ovarian torsion

The left ovary is enlarged, has an abnormal gray scale appearance and appears heterogeneous. Left ovarian torsion

There is scant internal and peripheral flow. Left ovarian torsion

Case ovarain torsion Gray-scale sagittal image reveals right ovary to be enlarged (7 cm) with peripheral follicles and areas of increased

echogenicity

Color Doppler demonstrates no flow within the ovary .

Power Doppler confirms almost no flow in the ovary .

a) Transverse ultrasonography shows a solid right adnexal mass; b) Longitudinal ultrasonography shows a tubular right ovarian vein extending superiorly from the adnexal mass towards the inferior vena cava (IVC). c) Transverse ultra-sonography shows thrombus in the right ovarian

vein adjacent to the IVC. Blood flow was visible in the IVC on colour Dopplerbut not in the ovarian vein

a) CT through the lower abdomen shows low attenuation thrombus distending the right ovarian vein. b) CT at the level of the kidneys shows thrombus extending into the IVC. c) CT shows a solid adnexal mass adjacent to

the enlarged uterus . Post-partum ovarian vein thrombosis POVT

a) CT through the lower abdomen shows low attenuation thrombus distending the right ovarian vein. b) CT at the level of the kidneys shows thrombus extending into the IVC. c) CT shows a solid

adnexal mass adjacent to the enlarged uterus .

Multiple tiny follicles are seen scattered throughout the right ovary /PCO .

Multiple, small follicles are seen scattered in the right ovary/PCO .

Multiple follicles are seen scattered in the left ovary. A densely echogenic area showing significant posterior acoustic shadowing is noted in the ovarian stroma/PCO

This image shows an echogenic ovarian mass. The posterior margins of the mass are obscured. These features along with the calcification seen in the previous image are suggestive of an ovarian dermoid .

PYOSALPNIX

TOA after 1o days

PYOSALPNIX

left TOA The uterus appears normal. A large cystic mass is seen in the left adnexa which demonstrates homogeneous, low-level internal echoes. The left

ovary is not visualized separate from this mass .

The cystic mass has a smooth wall except for one loculated area that exhibits thick irregular walls. The medial wall of the locule demonstrated blood flow

on Doppler [not shown here] .

The complex adnexal cyst is noted again, demonstrating low level internal echoes. A thin septum is seen extending from the wall. The mass

appears to be contained within the left ovary (compressed ovarian tissue is seen around the entire periphery) .

The right ovary is seen in this image and exhibits a small cyst with septations .

The right ovary in a different plane shows multiple cystic areas, some of which are septated. The

rest of the ovarian tissue appears somewhat inhomogenous.

Pubic osteomyelitis with an abscessheterogeneous soft tissue mass is noted anterior-inferior to the urinary bladder in the region of

the symphysis pubis, indenting the bladder contour. The bladder wall appears thickened adjacent to the lesion. The uterus appear normal .

Pubic osteomyelitis with an abscessThe heterogeneous soft tissue mass is noted again in this parasagittal image. Irregular echogenic areas are noted caudal to the mass. These echogenic areas cause complete shadowing beneath

them

Pubic osteomyelitis with an abscessThis image shows the extent of the mass more clearly. The mass appears to involve the superficial soft tissues.

The irregular echogenic areas are also seen more prominently here

Pubic osteomyelitis with an abscessThe mass in this transverse view shows a hypoechoic center. This is suggestive of

necrosis .

Pubic osteomyelitis with an abscess Color Doppler shows some flow within the mass .

Pubic osteomyelitis with an abscess Color Doppler of the mass in a different plane

Left ovarian abscess and related IUCD in situ

The endometrial cavity shows a linear, high amplitude echo. This possibly represents a retained piece of the IUCD.

Left ovarian abscess and related IUCD in situ The linear echo within the endometrial cavity is noted again in this image

Left ovarian abscess and related IUCD in situ complex left adnexal cystic mass is noted. The mass is septated and the left ovary could not be identified separately from it .

Left ovarian abscess and related IUCD in situ The left sided cystic adnexal mass exhibits thick septations. The fluid within the mass shows inhomogeneous echoes within .

Left ovarian abscess and related IUCD in situ The septated cystic left adnexal mass is seen again. The thick septations appear quite

irregular, raising a suspicion for neoplasm

Left ovarian abscess and related IUCD in situ The transvaginal scan better demonstrates the internal characteristics of the complex mass in the left adnexa. The thick septae and the inhomogeneous echoes in the

different fluid compartments of the mass are better appreciated in this view
