Özet
Objective: The purpose of the study both meningocele and myelomeningocele reviewing the clinical and pathological findings as well as to discuss the pathological diagnosis. Material and methods: Meningocel and myelomeningocele were retrived from the pathology files. Forty three cases with detailed clinical and radiological data were selected. Masson's trichrome performed on original sections from paraffin blocks. All sections from each case were reviewed. Results: There were 34 cases of myelomeningocele, 9 cases of meningocele. F/M ratio was 1.2 to 1. The age range of patients were from newborn to 4 months. 90% of cases were in the lumbosacral region. 31 cases of myelomeningoceles, and 3 cases of meningoceles were hydrocephalus. Chiari II malformation was seen in 88% of myelomeningocels and in 22% of meningoceles. Three patients had a clubfoot deformity. Microscopically, epithelial changes included ulceration, loss of appendages. Mesodermal findings included fibrosis (90% of cases), adipose tissue (62%), hypertrophic smooth muscle (18%), skeletal muscle (4%) and increased numbers of blood vessels (79%). Subepidermal calcification was noted in 2 cases. Neuroectodermal features, neuropil-like matrix and ependymal lining were noted in 34 and 15 cases respectively. Nerve fibers were identified varied from easily identifiable large myelinated nerve trunks to slightly increased numbers of fibers in 83% of the cases. Conclusion: Both clinical and pathological differences were seen among myelomeningoceles. These malformations involve ectoderm, neuroectoderm, and mesoderm. Definition of the pathological aspects of dysraphism will potentiate the understanding of these anomalies.
