Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Summary

A rare case of extradural tuberculous granuloma causing progressive quadriparesis was successfully treated with anti-tuberculous drugs. This finding highlights an unusual presentation of spinal tuberculosis.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Spinal Cord Pathology

Background:

  • Spinal tuberculosis (TB) is a significant cause of morbidity, often presenting as vertebral osteomyelitis or intradural-extramedullary lesions.
  • Extradural spinal TB granulomas are exceptionally rare, with limited documented cases in medical literature.

Observation:

  • A 49-year-old female experienced a 7-month history of progressive quadriparesis.
  • Imaging revealed a circumferential extradural lesion at the cervicomedullary junction and upper cervical cord.
  • The lesion was surgically debulked, and histopathology confirmed tuberculous granulation tissue.

Findings:

  • The patient's neurological deficits resolved following a course of anti-tuberculous drug therapy.
  • Post-treatment imaging demonstrated complete resolution of the granulomatous lesion.
  • Literature review did not identify similar cases of extradural tuberculous granuloma presenting as a primary spinal lesion.

Implications:

  • This case expands the spectrum of spinal tuberculosis presentations.
  • It underscores the importance of considering tuberculosis in the differential diagnosis of spinal cord compression, even with atypical extradural locations.
  • Early diagnosis and appropriate anti-tuberculous treatment can lead to favorable neurological outcomes.
