Diencephalic idiopathic gliosis: an unusual hypothalamic syndrome of dermopathy, diarrhea and growth arrest.

Abstract

This case report of a 16-year-old girl describes the association of chronic diarrhea and lower limb dermopathy with an unusual and widespread gliosis within hypothalamic and other diencephalic structures. This syndrome to our knowledge has not been previously reported. Hypothalamic disease was suggested during life by examination findings of sustained hypothermia, altered sleep-wake cycles and abnormal cortisol diurnal rhythms. Profound growth arrest from the age of 8 yr (growth velocity < 1.4cm/yr) despite normal levels of growth hormone and response to physiological stimuli were additional unusual features. Autopsy after sudden death at 16 yr showed extensive gliosis in hypothalamic and adjacent diencephalic structures with proportionately little neuronal loss--suggesting an unidentified stimulus to glial proliferation. In the absence of evidence of other organ dysfunction it is suggested that dermopathy and chronic diarrhea in this case may have an autonomic basis. The impaired tissue response to growth hormone could be due to chronic hypothermia or involvement of some other (unidentified) hypothalamic factor regulating growth velocity.
