Ecase # 16-C
Dena Kennedy, M.D.
August 5-9, 2002
CC: KW is a 55 YO woman with mid-back and chest pain, numbness in the
legs, weakness, jerkiness, heavy sensation and "feeling like body is melting
away."
HPI: While on recent 2 week trip to Washington, DC she developed aching
in the upper back, cramping and jerking sensations in her legs exacerbated
by stretching or pointing her toes down. She also noted a sensation in
both legs, as if her "nerves were on fire". She complained of a
heavy sensation in the thighs, more noticeable when standing. When she
walked she noted weakness and insecurity as though she might fall. Also
there was a sense of numbness of both side of rib cage and sensation "like
body is melting away."
PMH: stage III non-small cell lung CA on R, S/P radiation Rx, chemotherapy,
RU Lobectomy and excision of chest wall and ribs 2-4, 8/98. No known recurrence
but recent Sx of parasympathetic nervous system asymmetry of face/neck
and UE's; DM II; Obesity; Anemia; Asthma/COPD, hydrosalpinx.
FH: Epilepsy, Parkinson's Dz; Brain tumor; metastatic CA of unknown primary
Rx: Zocor; Vioxx
PE: Unremarkable
VS. Assistance needed to transfer from chair to exam table.
HEENT, Neck, Cor and lungs neg. Back without localized spinal or paraspinal
tenderness.
Neuro: alert and oriented. DTR's 2+ UE, 3+ RLE, 4+ LLE. Babinski's positive.
Sensory exam intact to light touch. Weakness distal greater than proximal.
Lab previous wk: Normal CMP except CO2 19. FBS 108. Lipids excellent.
CPK and aldolase nl. Hct 36.7.
Discussion
She has acute thoracic spinal cord compression until proven otherwise,
most likely from epidural extension of newly recurrent lung CA (unlikely
presentation of expanding hydrosalpinx with relatively acute and rapidly
progressive symptoms) ; diabetic myelopathy a reasonable consideration
as well. Other possibilities (such as spinal stenosis and cord compression
from disc disease, viral transverse myelitis, multiple sclerosis of spinal
cord, etc.) are much less likely.
Emergent evaluation with MRI and emergent treatment with Decadron and
radiation therapy is essential to preserve and improve nerve function
and prevent paraplegia. Time is of the essence
when evaluating and treating patients with this presentation.
MRI confirmed large epidural tumor in the thoracic canal from T1 through
T5 levels with tumor extending to the R T2-T3 foramen into the paraspinal
soft tissues. This tumor showed marked homogenous enhancement with severe
mass effect and edema of the cord. Cervical MRI revealed spondylosis with
degenerative discs and small protrusions. Chest and abdominal CT scans
1 month previously showed old scarring and post-surgical changes plus
minor incidental/non-contributory findings.
This patient responded to emergent radiation and Decadron, with prompt
improvement of symptoms, and was able to maintain ambulatory status. Further
staging evaluation was planned with the hope that treatment might allow
for extended survival, assuming the relapse was limited to the spine,
and would respond to XRT.

Abstract
Spinal cord compression is a relatively common complication of a number
of
malignant diseases. Back pain is the presenting symptom in more than 90%
of
cases. Early recognition and prompt treatment, while the patient can still
walk, are the most important factors in preventing permanent and
debilitating neurologic dysfunction. [References: 12]
