Two Lesions in the Junctional Zone Impinging on the Endometrium
This patient presents with menorrhagia. Two echogenic nodules (overlaid in green) are seen in the subendometrial layer, (junctional zone). They are in close proximity and do appear to have appositional relationships with the endometrial stripe. They appear to and distort the endometrial lining. These findings could account for the patient’s menorrhagia. Note that the uterus is retroverted Included in the differential diagnosis are submucosal fibroids, and dystrophic changes in prior foci of adenomyosis. An MRI would be helpful in further characterizing these lesions in the subendometrial layer

Hemorrhage into the Endometrial Cavity
The ultrasound is from a 33 year old female who had a cervical biopsy and then showed complex fluid in a distended endometrial cavity. the findings are consistent with hematocolpos, but in the appropriate clinical setting could represent pyocolpos

Post Cesarian Section Hemorrhage in Endometrial Cavity

Hemorrhage into Pelvic Cavity
 The CTscan is from a 28 year old female following a cesarian section showing a small amount of blood in the endometrial cavity and two large collections anterior to the low uterine segment. It is likely that the blood is from the incision of the LUS. A Hematocrit level is characterized by a clot (maroon)/fluid (serum yellow) level. Free fluid anterior to the liver is also noted.

Hemorrhage into Pelvic Cavity
 84070c.8s The CTscan is from a 28 year old female following a cesarian section showing a small amount of blood in the endometrial cavity and multiple large collections in the pelvist. It is likely that the blood is from the incision of the LUS. Hematocrit levels are characterized by sedimented red cells (maroon)/fluid (serum yellow) level. Free fluid (lighter yellow) is also noted.

Left Sided Ruptured Hemorrhagic Cyst with Free Blood in the Pelvis and Bleeding onto the Greater Omentum RLQ (pink)
This CT scan is that of a 27 year old female who presented with acute lower pelvic pain in mid cycle.  The findings of free blood in the pelvidss (maroon) the cyst (yelloow) with an enhancing rim9Bright red) and spillage of b;lood onto the greater omentum (pink let anterior) are consistent with a ruptured hemorrhagic cyst .

MRI

(T1/T2: II, ID, BD, BB, DD (I-iso, D-dark, B-bright)
Hyperacute – minutes to hours (DD => II)
– T1WI – hematoma hypointense (deoxyHb) => isointense
– T2WI – hematoma hypointense (deoxyHb) => isointense
Acute – 0-2 days (ID => BD)
– deoxyhemoglobin in intact RBCs with surrounding edema
– T1WI – hematoma isointense, low signal intensity (SI) edema
– T2WI – hematoma decreased SI at center, high SI edema
Subacute – 2-14 days (BB)
– deoxyhemoglobin changes to methemoglobin from outer to inner
– T1WI – outer core shows increased SI
– T2WI – Outer core shows increased SI due to shortened T1, longer T2
Chronic – 14 days (BB => DD)
– hemosiderin laden macrophages at periphery
– T1WI – inner core now also increased SI, rim has low SI
– T2WI – inner core also has increased SI, rim has low SI
Chronic – months later (DD)
– hemosiderin laden macrophages at periphery
– T1WI – mostly iso-/decreased SI, rim has lower SI
– T2WI – markedly hypointense rim has low SI – “blooms” with greater T2-weighting
