Amniotic Sheet (Synechia) vs Amniotic Band Amniotic Sheet Echogenic thick septa just like a separating septum in twin pregnancy, A broad base attached to uterine wall, free edge but not free‑floating No attachment to fetal parts, Often shows Doppler flow along the membrane Benign and incidental finding, but can influence fetal lie, Always a single sheet. Amniotic Band (ABS) Thin, irregular, free‑floating strands Attaches to fetal parts restricting movement Can cause constriction rings, amputations, craniofacial defects No Doppler flow It is associated with fetal abnormalities Case example: At 34 weeks, a scan shows a thick septum arising from the placental edge and extending across the uterine cavity to the anterior wall. This is a classic amniotic sheet; It is formed when the amnion drapes over a uterine synechia. An amniotic sheet is a normal variant with no fetal risk whereas an amniotic band is pathological and can cause serious fetal deformities. Amniotic sheet 👇👇

THE “KEYHOLE SIGN” YOU SHOULD NEVER MISS ON FETAL ULTRASOUND 🚨 ​🔑 THE KEYHOLE SIGN is an important prenatal ultrasound finding in male fetuses suggestive of Posterior Urethral Valves (PUV). 📸 On ultrasound, the dilated posterior/proximal urethra along with a distended urinary bladder create a configuration that resembles a keyhole, hence the name. 📍 Posterior Urethral Valves (PUV), also known as Congenital Obstructing Posterior Urethral Membranes (COPUM) represent the most common cause of congenital urethral obstruction in male infants and can lead to obstructive uropathy, bladder dysfunction, and even long-term renal compromise if not addressed. #Ultrasound #FetalUltrasound

The tau sign represents the appearance of a persistent primitive trigeminal artery on the sagittal plane of an angiogram or on sagittal MRI. It resembles the Greek letter τ, pronounced "tau." 🚨 SIMPLE QUIZ 1. The vertical and anterior horizontal limbs of "tau" are formed by the ____________ artery. 2. The posterior horizontal limb is formed by the ________________ artery.

1/Do radiologists sound like they are speaking a different language when they talk about MRI? T1 shortening what? T2 prolongation who? Here’s a translation w/an introductory thread to MRI.

✅حقن المخدر الموضعي تحت الجلد خلف الـ lateral malleolus راح يخدر الـ sural nerve، وهذا العصب أصلاً عصب حسي بحت ما فيه وظيفة حركية، وهو يجي من تفرع الـ tibial nerve والـ common fibular nerve مع بعض، ويمشي من الجزء الخلفي للساق لين يوصل لمنطقة الكعب الخارجي ويطلع على ظهر القدم من الجهة الخارجية وحتى الخنصر، يعني الـ lateral aspect of the foot والـ little toe هي المنطقة اللي راح تتخدر، والفايدة من هالحقنة إنك تقدر تسوي أي إجراء جراحي أو تشخيصي في هالمنطقة بالذات زي عمليات الـ lateral foot، أو تثبيت كسور في منطقة الـ 5th metatarsal، أو حتى أخذ خزعة من الجلد في هالمنطقة، وأحياناً يستخدمونه في حالات الـ chronic pain اللي تكون في توزيع هذا العصب زي الـ sural neuritis، والحقنة نفسها سهلة وآمنة لأن العصب يمشي مع الـ small saphenous vein خلف الـ lateral malleolus مباشرةً، ف الـ landmark واضح وما تحتاج ultrasound في الغالب.

✅Diffuse leptomeningeal glioneuronal tumor (DL-GNT). 💡Think of it when you see widespread leptomeningeal nodules with cystic-like components in a child. It can mimic infection or metastatic spread, but slow progression and this pattern should raise suspicion. doi.org/10.3390/diagno…
