Acute meningitis can be complicated by intracranial complications commonly and rarely by spinal cord dysfunction. The causes of spinal cord dysfunction are cord compression, ischemic infarction of the cord, and acute myelitis. Magnetic resonance imaging (MRI) of the cord is the choice of investigation which not only helps to rule out any compressive lesion but will also confirm the diagnosis of myelitis. The usual findings of myelitis on MRI spine are the hyperintensities in T2-weighted images that predominantly involve the gray matter and usually extend from the cervical to the lumbar cord. Usually, patients are left with some residual deficits including spasticity, weakness, walking difficulties, and bowel–bladder dysfunction. We report a case of acute meningitis which was complicated by acute transverse myelitis.

| Introduction|| |
Acute meningitis can be complicated by intracranial complications such as cerebrovascular accident, brain edema, hydrocephalus, or hearing impairment, as well as systemic complications, such as septic shock, adult respiratory distress syndrome, or disseminated intravascular coagulation., Spinal cord dysfunction is usually an infrequent complication which is more common in children but has been reported in adults as well., The causes can vary from cord compression to ischemic infarction of the cord and acute myelitis. Cord compression can be due to spinal abscess or hemorrhage following lumbar puncture, whereas cord infarction can be due to vasculitis, shock, herniation, or arachnoiditis. Acute transverse myelitis is a rare cause of myelopathy, with an incidence of 1 to 4 cases/million/year., We report a case of a 34-year-old gentleman with acute meningitis, who developed Acute transverse myelitis as a complication which was confirmed by magnetic resonance imaging (MRI) of the spine.
| Case Report|| |
A 34-year-old man from India male presented with a 3-day history of headache, neck pain, and low back pain. He was previously healthy and had no medical history in the past. He is unmarried and is working as a technical engineer. He is a nonsmoker and nonalcoholic. This was followed by progressive weakness in both legs and unable to pass urine. Neurological examination revealed neck stiffness with paraparesis, with power of Grade 2 in both legs. It was associated with hypotonia and hyporeflexia in both lower limbs with equivocal planters. He had reduced sensation with sensory level at T10. He was admitted as a case of suspected meningitis with signs of spinal cord dysfunction and was started on antibiotics. An urgent cerebrospinal fluid (CSF) examination showed high white blood cell (WBC) of 4278 (90% neutrophils), high protein of 1.88 g/L, low glucose of 2.4 mmol/L (<50% of serum glucose), and Gram stain and culture of CSF were negative. The CSF viral panel, tuberculosis (TB) smears and cultures, and TB polymerase chain reaction were negative.
The power in the lower limbs worsened to zero in few hours of admission; therefore, an urgent MRI spine was done which demonstrated abnormal cervicodorsal signals from C7–D11, representing transverse myelitis [Figure 1]. MRI brain was normal. As the patient showed very slow recovery initially, he was started on steroid and antituberculous medication, but antituberculous medication was stopped after negative culture for TB. Repeated CSF analysis in a week time showed marked improvement with WBC count dropped to 77 (88% lymphocytes) and normalization of glucose and protein. MRI of the spine was repeated after 1 week which showed reduction of abnormal signal intensity. After initial stabilization, he was transferred to a rehabilitation center with tapering dose of steroids and 10 days of antibiotics.

The patient showed marked clinical improvement at the rehabilitation center after 6 weeks of presentation with increase in the power grade of 4/5 in bilateral lower limbs; however, his bladder and bowel control was still absent. Repeat MRI at 6 weeks showed complete resolution of abnormal findings seen before [Figure 2].

| Discussion|| |
Our case report is an example of a rare complication of acute meningitis in adults. The usual causes of spinal cord dysfunction in acute meningitis are compression by spinal abscess, epidural hemorrhage, and ischemic infarction of the cord due to vascular compromise., However, acute myelitis has been reported previously as a cause of cord dysfunction in patients with acute meningitis., Although it is more common in children, it has been reported in adults also. The most frequent initial symptoms are motor symptoms such as quadriplegia or paraplegia, sensory symptoms, and bladder–bowel dysfunction., Spinal cord symptoms become evident from the time of diagnosis of meningitis and last for a variable time and even some patients are left with residual deficits. The most common reported residual deficits are spasticity, weakness, walking difficulties, and bowel–bladder dysfunction. Our patient had slight residual weakness in the lower limbs with bladder and bowel dysfunction.
The cord dysfunction is not related to the causative organism of meningitis as even it has been reported in those cases of meningitis where no organism was isolated.,, In our case, no bacterial organism was isolated, and TB workup and viral screen were also negative. MRI of the spine is critical to evaluate patients with suspected cord dysfunction., MRI of the spine will help to exclude compression as well as to distinguish various types of transference myelitis, as the prognosis, risk of recurrence, and treatment options may differ among these distinct entities.,
The nature and extent of spinal cord dysfunction associated with meningitis in adults was first described by Kastenbauer et al. where the most common finding which was present on MRI T2-weighted images was hyperintensities predominantly involving the gray matter which extended from the cervical to lumbar cord. The MRI of the spine of our patient showed hyperintensities on T2-weighted images extending from C7 to T11 level. A literature review of patients aged 2 years or more with similar complications showed that young children have cervical cord lesions, whereas the majority of adolescents and adults have thoracic or lumbar lesions., Clinical follow-up of these patients suggests that myelitis during acute bacterial meningitis, has an unfavorable prognosis and all patients have some persistent neurologic deficits, regardless of age., Our patient showed significant improvement over a period of few weeks in terms of weakness and spasticity, but bladder and bowel incontinence persisted. A following MRI of the spine in our patient showed complete resolution of the hyperintensities.
| Conclusion|| |
This case demonstrates that myelopathy is an infrequently reported complication of bacterial meningitis in adults that can occur due to vasculitis, infarction, autoimmune myelopathy, or direct infection of the spinal cord. The aim of presenting this case is to consider this complication in patients with meningitis who develop the symptoms of acute cord dysfunction.
