Imaging SBA Module 5 Flashcards
Round pneumonia
Doesn’t always have air bronchograms
Osteoid osteoma
Lucent lesion with periosteal reaction.
Pain at night.
Wilms
Compress rather than invade local structures.
Can invade/spread via renal vein and IVC to lungs.
Rare to affect spinal canal (neuroblastoma does this)
Unicornate uterus
Relative lateral lie of uterus with dysmenorrhoea.
MRI recommended
Mesoblastic nephroma vs cystic nephroma
Mesoblastic can present or be seen in antenatal or neonatal period
Prepubertal uterus dimensions (5yo)
AP diameter 1cm, CC length 2.5-4cm
Ix for suspected neuroblastoma on US
CT chest, MRI head, neck, abdo, pelvis,
MIBG, skeletal scintigraphy
Adrenocortical carcinoma
Large suprarenal mass
Macroglossia (associated with Beckwith Weidermann)
Acne/precocious puberty
Uterus didephys
2 uterine horns separated by cleft of solid tissue with no communication.
Can cause unilateral obstruction and renal agenesis.
Can cause hydrometrocolpos
Additional drugs used in Meckels scan
Pentagastrin, Glucagon, Cimetidine
Hypoplastic left heart assoiciated with
Aortic coarctation in 80%
Bochladek hernia
90% of congenital diaphragmatic hernias.
Associated with neural tube defects, malrotation and cardiac defects
Osgood schlatter
Partial avulsion of tibial tubercle is not always seen on XR.
MRI: Increased size and signal in the patellar tendon on T1 and T2, distension of deep infrapatellar bursa and avulsion injury.
Thyroglossal duct cyst
Cystic structure, moves with tongue, no more than 2cm from midline
Pilocytic astrocytoma
Cyst with nodule, often midline in 3rd ventricle, brainstem or optic chiasm.
3rd ventricle ones can cause hydrocephalis, raised ICP and 6th nerve palsy
TTN
Small pleural effusions and increased interstitial fluid with normal lung volumes.
Associated with C section
