trauma, prolonged fever, unexplained weight loss, anorexia, cough, hemoptysis,
prolong use of steroid or close contact with known TB patient.
7. History of present illness (Cont.)
With the above complaints, he visited Mugda Medical college hospital and then
referred to Neurosurgery department ,DMCH for better management.
42. Laminoplasty
Various methods commonly used for laminoplasty.
(a) Single-door suture
technique. (b) Double-door allograft. (c) Single
door
allograft. (d) Single-door plate fixation.
46. Points in favour Points against
Schwannoma Most common nerve sheath mass
•
"dumbbell-shaped' transforaminal mass
• Hemorrhage, cystic, or fatty degeneration
• Solitary spinal lesion more likely schwannoma than NF
• Bony remodeling– Thinned pedicle
.
• No uniform enhancement pattern
Neurofibroma • Target sign
• Hemorrhage, cystic, or fatty degeneration
Bulky multilevel spinal nerve root tumors
in patient with
stigmata of neurofibromatosis type 1
extramedullary
ependymoma
Ependymoma: Unusual
differential for a totally
No Cap sign: Hemosiderin at cranial or
caudal margin
Editor's Notes
Reflexes can be graded
0= absent
+-= present only with reinforcement
1+=present but depressed
2+= Normal
3+= increased
4+= clonus
Showing iso to hypointense lesion at the level of C7 and D1 vertebra with fusiform dilatation of spinal cord at this level.
Hyperintense signal change above the lesion up to C6 and below the lesion up to D2 vertebra
Cervical lordotic curvature is straightening with normal disc space .
Anterior and posterior CSF column is maintained.
Rest of the spine screening is normal.
Showing iso to hyperintense lesion at the level of C7 to D1 vertebra with fusiform dilatation of spinal cord at this level.
Showing iso to hypointense oval shaped lesion at the level of C7 to D1 with peripheral hyperintense signal change extending superiorly up to C6 and inferiorly up to D2 vertebra
Homogenous contrast enhanced ovoid shaped lesion at the level of C7 to D1 vertebra.
Iso intense lesion in the central portion of the spinal cord with poorly demarcated outline
Iso to hyperintense lesion in the central portion of the spinal cord with poorly demarcated outline
Homogenous contrast enhanced circular lesion on central portion of the cord
• Target sign more common with NF than schwannoma
• Hemorrhage, cystic, or fatty degeneration more common
with schwannoma
Solitary spinal lesion more likely schwannoma than NF
Bony remodeling due to large intraspinal or
transforaminal mass
– Thinned pedicle, enlarged neural foramen, vertebral
body scalloping, widened interpedicular distance
Spinal Meningioma
• Thoracic tumor in female patient is more likely meningioma
• dural "tail"
• calcification
Broad dural attachment
• Strong homogeneous enhancement
Neurofibroma
Bulky multilevel spinal nerve root tumors in patient with
stigmata of neurofibromatosis type 1
Target sign on T2WI
Ependymoma
Cap sign: Hemosiderin at cranial or caudal margin
