Intracerebral Calcifications Associated with Failure to Thrive and Macular Degeneration in an Adolescent: A Case Report.

BACKGROUND: The clinical picture of intracerebral calcification is so varied that it constitutes an essential element of a wide range of clinical syndromes of variable expression that continue to be described. In this article, we discuss the diagnostic possibilities of basal ganglia calcification considering the association of failure to thrive and macular degeneration in our patient.

CASE: A 17-year-old male patient of Congolese origin consulted us for a pyramidal syndrome consisting of upper limb tremors during mobilization and dysgraphia. The patient also presented with a distance vision disorder for which the ophthalmological examination revealed poor visual acuity in both eyes (2/10) and macular degeneration in the left eye. On physical examination, we noted a short stature with a small head circumference in relation to age. The brain scan revealed the presence of bilateral striato-pallidal calcifications giving the appearance of Fahr's disease. However, the association of delay of stature development with microcrania, macular degeneration with reduced visual acuity and basal ganglia calcifications could suggest a wide range of syndromic hypotheses, the most likely of which is Rajab-type cerebral calcification.

CONCLUSION: The association of failure to thrive, macular degeneration, and cerebral calcification of the basal ganglia is revealed as a particular phenotype compared to cases reported in the literature. An in-depth analysis would be necessary to identify a possible genetic basis.
