Chorio-Amnion Separation
DEFINITION COMPLICATIONS
Chorioamniotic separation (CAS) is an intra-uterine event which can occur in pregnancy and is characterised by separation of placental (chorion) and fetal (amnion) membranes.
Sonographic detection of a small chorioamniotic membrane separation especially before 14 weeks gestation is considered a benign incidental finding. A careful search for aneupliodic and other developmental anomalies is often recommended if a spontaneous chorioamniotic separation is detected after 14 weeks.
Recognised complications following a large separation include :
1. Miscarriage2. In utero fetal death umbilical
cord complications3. Pre-term delivery4. Amniotic band formation

DEFINITION GCTTS ULTRASOUND FINDINGS ARE
Giant cell tumours of the tendon sheath (GCTTS), also known as pigmented villonodular tumour of the tendon sheath (PVNTS) or extra-articular pigmented villonodular tumour of the tendon sheath, are uncommon and usually benign lesions that arise from the tendon sheath. It is unclear whether these lesions represent neoplasms or merely reactive masses.
Ultrasound Ultrasound is useful as it allows not
only the characterisation of the lesion but also is able to demonstrate the relationship with the adjacent tendon. On dynamic scan, there is free movement of the tendon within the lesion. Typically they appear as: associated with the volar surface of
the digits does not move with flexion or
extension of adjacent tendons usually homogeneously hypoechoic,
although some heterogeneity may be seen in echotexture in a minority of cases
most will have some internal vascularity

LEVATOR SLING The levator ani, also known as the muscular pelvic diaphragm, is the musculotendinous sheet that forms the majority of the pelvic floor, supports the pelvic viscera, and aids in the urinary and faecal evacuation as well as maintaining continence.
The levator ani has three main components, each of which is paired :
1. pubococcygeal (pubovisceral) muscle1. subparts: puboperineal,
pubovaginal, puboanal2. iliococcygeus muscle3. puborectalis muscle

URETEROCELE
Ureterocoeles represent congenital dilatation of the distal-most portion of the ureter. The dilated portion of the ureter may herniate into the bladder secondary to the abnormal structure of vesicoureteric junction (VUJ).Epidemiology
SIMPLE URETEROCELE TYPES
URETEROCELE
There are two main types of ureterocoele, both of which are the result of cystic ectasia of the subepithelial portion of the ureter as it inters the bladder.• Simple: a ureterocoele
that occurs at a VUJ in a normal position.
• Ectopic: that which occurs at a VUJ whose site is abnormal.
