Radiology Spotters

1. spotters

3. Torch infection
• Intracranial Calcifications
• CMV: Periventricular calcifications
• Toxoplasmosis: Diffuse, scattered intracranial
calcifications
• Hydrocephalus & Ventriculomegaly
• Seen in Toxoplasmosis and CMV

5. • Hirayama disease
• Rare, non-progressive lower motor neuron
disorder
• Neutral and flexion MRI showing anterior
translation of posterior dura on flexion MR
with flow voids and associated cord thinning

7. Cervical myelomeningiocele
• Absent posterior neural elements of cervical
vertebrae with herniation of the cord through
this defect to project into large
myelomeningocele

9. Vestibular Schwannoma
• “Ice Cream Cone” Appearance on MRI:
• Scoop = mass in the cerebellopontine angle (CPA)
• Cone = extension into the internal auditory canal (IAC)
• Clinical Findings:
• Unilateral sensorineural hearing loss (most common)
• Tinnitus
• Imbalance or vertigo
• Possible facial numbness or weakness (if large tumor
compresses CN V or VII)

11. Pericallosal lipoma
• T1 hyperintense fat intensity lipoma noted in
the peri callosal region
• Associations:
• Corpus callosum agenesis or dysgenesis
• Other midline anomalies (e.g., interhemispheric
cysts)

13. Erdheim-Chester Disease (ECD)
• Rare non-Langerhans cell histiocytosis
characterized by xanthogranulomatous infiltration of
multiple organs, especially bones, kidneys, and CNS.
• Classic Imaging Sign: Hairy Kidney Sign –
symmetric perirenal soft tissue infiltration on CT/MRI
due to retroperitoneal involvement

15. Jeune Syndrome (Asphyxiating Thoracic
Dystrophy)
• Radiological Hallmark: Bell-shaped narrow thorax
with short, horizontally oriented ribs—leads to
respiratory distress in infancy.
• Skeletal Dysplasia: Rare autosomal recessive
condition with shortened long bones, polydactyly,
and renal/liver involvement in some case

17. Agenesis of carpous callosum
• Congenital absence (partial or complete) of the
corpus callosum causing variable
neurodevelopmental symptoms like seizures and
developmental delay.
• Radiology: Neurosonogram shows widely spaced,
parallel lateral ventricles with absent cavum septum
pellucidum and elevated frontal horns (“racing car”
sign)

19. Ewings sarcoma
• Malignant bone tumor commonly affecting
diaphysis of long bones in children and adolescents.
• Classic radiological sign: "Onion-skin" periosteal
reaction on X-ray due to layered new bone
formation.

21. Ebstein anomaly
• Congenital malformation with apical displacement
of the tricuspid valve leaflets causing “atrialization”
of the right ventricle.
• Chest X-ray shows a “box-shaped” enlarged heart
with cardiomegaly and a prominent right atrium.
