Clinical and tomographic aspects of 29 cases of phakomatose in Guinea

The purpose of this report is to describe 29 cases of phakomatosis including 18 cases of tuberous sclerosis (Bourneville) and 11 cases of neurofibromatosis (von Recklinghausen) observed over a 10-year period at the Neurology Department of the University Hospital Centre in Conakry, Guinea. Findings during this period were consistent with those classically reported in the literature: high frequency of advanced skin lesions coalescing into massive tumours, occurrence of seizures of all types and development of a wide variety of complications as a result of late diagnosis. Our experience underscores the need for follow-up and surveillance of these patients by somatic studies based on neurological, ophthalmologic and tomographic data depending on clinical findings.
