Solitary Langerhans cell histiocytosis orbital lesion: case report and review of the literature

Solitary eosinophilic granuloma is a rather benign and localized form of Langerhans's cell histiocytosis. Definitive diagnosis is made by histopathology including immunohistochemical detection of S-100, HLA-DR and CD1a antigens. We report the case of a twenty-five year old boy presented with headache and orbit's pain. A CT scan showed a left supero-lateral orbital mass with evidence of bone erosion. The different options of treatment are discussed and the literature is reviewed

Cerebrotendinous xanthomatosis (van Bogaert-Scherer-Epstein disease): CT and MR findings.

PURPOSE: To describe the CT and MR findings in the brain and spinal cord of patients with cerebrotendinous xanthomatosis and to seek possible correlations between clinical, biochemical (cholestanol levels), and neuroimaging findings. METHODS: Ten patients with well-defined clinical and biochemical diagnoses of cerebrotendinous xanthomatosis were examined. Brain CT was performed in eight cases. In all patients MR was obtained using spin-echo and gradient-echo sequences. In eight patients spine MR was also performed. RESULTS: Neuroradiologic findings included diffuse cerebral and cerebellar atrophy. In half the cases, atrophy of the brain stem and corpus callosum was also found. In the majority of patients cerebellar bilateral focal lesions and mild white matter signal alterations were present. Spinal cord MR did not show signal abnormalities or atrophy. CONCLUSIONS: We found cranial alterations in patients with severe neurologic impairment, but there was no correlation with cholestanol plasma levels. No spinal cord abnormalities were present
