21-year-old female with an acute onset of a unilateral sixth cranial nerve deficit. Brain MRI showed at least a dozen white matter lesions, one of them contrast-enhancing. Sensory evoked potentials showed a bilateral increase in latency. Multiple sclerosis was diagnosed, and the patient was treated by corticosteroids, followed by improvement of symptoms. The first follow-up revealed no focal neurological signs with a history of a transitory unilateral lower limb hyposthenia. On the second visit, a horizonto-rotatory nystagmus and irregular paraesthesia in the right toes are documented.

11-months-old male showed signs of tumefaction in the left frontotemporal region. An ultrasound showed a solid noncalcified neoformation, and a brain CAT scan showed a small solid lesion resulting in erosion of the cranial theca both in the external and internal table. Based on clinical status and tomodensitometric appearance, the diagnosis of suspected eosinophilic granuloma or hystiocytosis X was made, and a surgical curettage of the craniolacunia was recommended in order to comfirm the diagnosis.

65-year-old male experienced loss of consciousness, and a CT scan showed a left temporal mass which was confirmed by MRI. The patient underwent Stereotacti biopsy of mass, and Histological examination gave a diagnosis of anaplastic astrocytoma. He started chemoradiation with fotemustine (nitrosourea alkylating agent). Repeated MRI showed progression with mass effect, mild uncal herniation and enlarging ventricles. He has stable expressive aphasia and hemisyndrome, lethargy and decreased motivation. His treatment was switched from phenobarbital to levetiracetam.
