MRI
Abnormalities

2. INTRACONAL
EXTRAOCULAR
MELANOMA
. It is characteristic
that during intervals
of venous
hypertension varices
expand

3. CAVERNOUS
HAEMANGIOMA
Solitary ,well
circumscribed
lesion,mostly in
lateral intraconal
space

4. ORBITAL CAVERNOUS
HEMANGIOMA

5. OPTIC NERVE GLIOMA
•Seen with
tubular
enlargeme
nt with
kinking of
optic
nerve

6. OPTIC NERVE GLIOMA
• Axial T1 • Axial T2 • Coronal T1 Gd+

8. PLEOMORPHIC ADENOMA
LACRIMAL GLAND
• Smooth,
encapsulated
outline
• Excavation of
lacrimal gland
fossa without
destruction

9. ORBITAL
RHABDOMYOSARCOMA
. On MRI, RMS
appears as a
well-defined,
homogenous
mass

10. PET-MRI

11. pediatric and pregnant oncologic
patients with need for follow-up
studies, can take advantage of the
reduced radiation exposure of
PET/MRI compared to PET/CT.
These advancements hold promise
for superior diagnostic capabilities,
improved image quality with reduced
PET-image noise, more accurate
co-registration of PET-data with MRI

12. Patients
with lymphomas,
neuroblastomas and soft tissue
sarcomas
may benefit from PET/MRI
evaluation.

13. Orbital Ultrasound

14. Ultrasound is
one of the
most common
imaging tests
to confirm a
child has
retinoblastoma
.
