Case 1
This lesion is likely to be located at: 6 or 12 o’clock (midline on the cc view) 3 or 9 o’clock 3 or 6 o’clock 9 or 12 o’clock
T1W STIR
Lesion seen on the MRI is likely: Fibroadenoma Fat necrosis Lobular cancer Lymph node (note the bean-like shape, fatty hilum)
Case 3 CC ML
The next step in following up these calcifications is: Nothing (Classic layering calcifications on lateral view, amorphous on CC, Milk of Calcium) Ultrasound Follow up in 6 months Biopsy
Case 4
Impression of report would be BIRADS 1 BIRADS 2 BIRADS 3 BIRADS 4 (Spiculated mass)
Case 6 The view that includes the most breast parenchyma is: Crainocaudal view Mediolateral view Mediolateral oblique view Exaggerated craniocaudal view
Case 7
A lesion showing this enhancement curve on breast MRI is most likely to be: Normal breast parenchyma Fibrocystic change Fibroadenoma Invasive cancer (rapid rise with early washout, < 4min) Type 1 Progressive Type II plateau Type III washout
Case 8 R breast 12
The most probable diagnosis: Fibroadenoma Simple Cyst (not anechoic) Ductal cancer (usually hypoechoic and irregular with shadowing) Fat necrosis
Case 9 Mucinous tumor (bright on T2) Mucinous tumor T1W Fibrocystic change T2W Post Contrast
Diagnosis please: Invasive lobular cancer DCIS Fibrocystic disease Mucinous cancer 2 and 3 3 and 4 1,2 and 3 All of the above
Case 10
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
Case 11 Diagnosis!
Case 11 Bicornuate uterus The right cornu appears hyperintense on both T1&T2WI. Left cornu is normal. No e/o hematometra
Case 12 Where is the mass coming from ?
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
Case 13
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
Case 14
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
Case 15 Diagnosis!
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
