3 or 6 o’clock
9 or 12 o’clock

4. T1W
STIR

5. Lesion seen on the MRI is likely:
Fibroadenoma
Fat necrosis
Lobular cancer
Lymph node (note the bean-like shape, fatty hilum)

6. Case 3 CC ML

Crainocaudal view
Mediolateral view
Mediolateral oblique view
Exaggerated craniocaudal view

11. Case 7

T2W
Post Contrast

16. Diagnosis please: Invasive lobular cancer DCIS Fibrocystic disease
Mucinous cancer

All of the above

17. Case 10

18. Case 10 Chorioangioma of placenta
Most common neoplasm of placenta consisting of vascular mass arising from chorionic tissue
Larger than 5cm have increase rate of complications: polyhydramnios,CCF,pretem labor, IUGR
USG reveals well circumscribed hypoechic lesion around cord insertion site.
Always look for fetal hydrops

19. Case Diagnosis!

20. Case 11 Bicornuate uterus
The right cornu appears hyperintense on both T1&T2WI. Left cornu is normal. No e/o hematometra

21. Case 12 Where is the mass coming from ?

22. Case12 Cervical fibroid
A large well defined mass is seen to arise from cervix. It causes displacement of uterus superiorly and to the right
Multiple hyperintense areas within it are due to cystic degeneration

23. Case 13

24. Case 13 Hydropic degeneration of placenta
Embryonic demise
Multiple hpoechoic lesions are seen in placenta s/o degenerative /hydropic changes secondary to fetal demise
b HCG titres were declining

25. Case 14

26. Case 14 Ovarian fibroma
Well defined lesion in right ovary, hypointense on both T1 &T2WI
Fbroma is sex cord stromal tumor with low grade malignant potential
Hypo/hperechoic on USG. Variable appearance according to presence of fibrous content

27. Case 15 Diagnosis!

28. Case15 Ovarian hyperstimulation syndrome
Ovarian Hyperstimulation Syndrome (OHSS) is a potential complication of ovarian induction therapy
Imaging reveals bilateral ovarian enlargement with thichened endometrium and free fluid.
It could be life threatening hence early diagnosisis imperative
