Recurrent meningoencephalitis and ascending myelitis caused by dermal sinus tract of extraordinary length
Abstract:
The case of an infant with a dermal sinus tract, recurrent meningitis, ascending myelitis and a fatal outcome is described. The extraordinary extent of the cord affection with abscesses up to the level of the lower brainstem, and the presence of squamous epithelium within them, is difficult to explain on the basis of current concepts of the formation of dysraphic dermal sinus tracts. Morphogenetic, clinical and radiological aspects are discussed.
Insights
A rare infant case details a dermal sinus tract leading to severe spinal cord disease and death. The extensive cord involvement and presence of squamous epithelium challenge current theories on congenital dermal sinus tract formation.
Area of Science:
- Neurology
- Developmental Biology
- Pathology
Background:
- Dermal sinus tracts are congenital anomalies that can lead to serious neurological complications.
- Recurrent meningitis and myelitis in infants often indicate underlying structural abnormalities.
Observation:
- This case describes an infant presenting with a dermal sinus tract, recurrent meningitis, and ascending myelitis.
- The infant experienced a fatal outcome due to the extensive neurological involvement.
Findings:
- The spinal cord was affected up to the lower brainstem by abscesses.
- Squamous epithelium was found within these abscesses, which is unusual for dysraphic dermal sinus tracts.
- The extent of the cord affection was extraordinary and difficult to explain with current concepts.
Implications:
- This case highlights the potential severity of dermal sinus tracts and the need for early diagnosis and intervention.
- The findings may prompt a re-evaluation of the pathogenetic mechanisms of dysraphic dermal sinus tracts.
- Further research into the morphogenetic, clinical, and radiological aspects of such cases is warranted.
