Spinal Cord: Cross-sectional Anatomy

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Summary

Neurobrucellosis, a rare complication of Brucella infection, can cause unusual deep gray matter lesions. Early treatment with antibiotics led to significant clinical and radiological improvement in a patient with this condition.

Background:

Brucellosis is a zoonotic infection with diverse clinical manifestations.
Neurobrucellosis is a rare but serious complication, often presenting as meningitis or cranial neuropathies.
Demyelinating lesions are recognized in neurobrucellosis, but deep gray matter involvement is atypical.

Observation:

A 27-year-old man with recent Middle East travel presented with fever, altered behavior, and hemiparesis.
Cerebrospinal fluid analysis revealed elevated protein with sterile bacterial cultures.
Cranial MRI demonstrated bilateral white matter and basal ganglia hyperintensities.

Findings:

Serum Brucella agglutination titer was significantly elevated (320 IU).
The patient received a 4-month course of antibiotics including ceftriaxone, doxycycline, and rifampicin.
Clinical improvement and reduction in MRI lesions were observed after 3 months of treatment.

Implications:

This case highlights the unusual presentation of neurobrucellosis with deep gray matter involvement.
Prompt diagnosis and appropriate antibiotic therapy are crucial for favorable outcomes in neurobrucellosis.
Further research is needed to understand the pathogenesis and optimal management of atypical neurobrucellosis presentations.
