Introduction. Langerhans Cell Histiocytosis (LCH) is a rare chronic granulomatous, usually multisystem disease of elusive etiology, with peak incidence in early childhood and slow progressing course. Isolated brain histiocytosis is a very rare condition and neurological finding does not correlate with the extent of space-occupying anatomical lesions and degenerative changes. Case report. A girl, age 2.5 years was presented with diabetes insipidus and nearly fatal full spectrum isolated brain histiocytosis. Brain magnetic resonance imaging (MRI) showed multiple nodules with perifocal edema, the most prominent in the projection of the hypothalamus/pituitary and the stalk and in the region of the pineal gland. Identical nodules were present in both caudate nucleus and putamen, left insular subcortex, both temporal lobes, tegmental area of the midbrain, central part of pons and medulla, both cerebellar hemispheres and leptomeningeal membranes. The pattern resembled snow balls and flakes. Biopsy showed positivity for vimentin, S-100, CD-68 and CD1a markers. Treatment protocol LCH-III was not successful and a salvage treatment was refused by parents. She appeared again at the age of 7 with growth deceleration and fully developed precocious puberty. The control MRI of the brain revealed similar nodules in certain regression. Due to central precocious puberty, treatment with luteinizing hormone–releasing hormone (LH-RH) analogue was introduced. School performance was mediocre with cocktail-party effect behavior and slower speech. Conclusion. Brain histiocytosis is potentially fatal disease with chronic, variable, slowly progressive course and unpredictable responses to treatment protocols. © 2020 Inst. Sci. inf., Univ.

Background Primary intraventricular meningiomas (IVMs) make up 0.5%–5% of all intracranial meningiomas and represent one of the most challenging lesions in neurosurgery. Methods Between 1990 and 2013, 42 patients (30 female, 12 male; mean age, 43.6 years) underwent resection of their IVM. The removal was performed by a posterior parietal approach in 19 of the 40 lateral ventricle tumors, and 1 third ventricle meningioma. The transcallosal approach was used for 3 meningiomas, and patients with other lesions underwent temporal (7 cases) and temporoparietal approaches (12 patients), respectively. Results The most common presenting signs were increased intracranial pressure (83.3%), visual impairment (78.6%) and cognitive changes (50%). Forty lesions (95.2%) arose in the lateral ventricles, and 2 (4.8%) in the third ventricle, ranging in size from 3 to 10 cm. Total removal was achieved in 39 cases and the pathology report disclosed World Health Organization grade I lesions in 41 cases. Hydrocephalus, cerebrospinal fluid leakage, and cerebral edema were the postoperative complications (7.15%); 1 patient died of respiratory problems not directly related to surgery. Thirty-five patients (83.3%) showed a 6-month Glasgow Outcome Scale of 5. One patient, who underwent partial resection, presented a recurrence after 1 year that remained stable until last follow-up. Conclusions IVMs usually reach a large size before being diagnosed. Surgical treatment is the most suitable option and total removal should represent the main goal of the procedure. The posterior parietal transulcal approach and the temporoparietal approach are the most common surgical routes used in our series. © 2016
