Superficial siderosis of the central nervous system is a rare condition characterized by deposition of haemosiderin in the leptomeninges and in the subpial layers of the brain and spinal cord. With the widespread use of magnetic resonance imaging, an increasing number of cases of superficial siderosis are being discovered, secondary forms being more frequent than idiopathic ones. We report a 78-year-old man in oral anticoagulant therapy, who presented neurosensory hearing loss, gait ataxia and spastic paraparesis. Magnetic resonance imaging suggested the diagnosis of superficial siderosis of the central nervous system, without an evident bleeding source.
The authors report their personal experience with the administration of microdoses of morphine hydrochloride by the intraventricular route through a subcutaneous reservoir for the treatment of paraneoplastic painful syndrome of the cervicofacial region in 38 patients. The results obtained are very encouraging.
A series of 57 patients with root syndromes or compressive myelopathy were operated upon by a modified Cloward technique. No bone grafts were used. The patients were observed for 6 months to 5 years after surgery. Of the 47 patients with radiculopathy, 44 were cured and three complained of minor pains in their arms. Of the 10 patients with myelopathy, three were greatly improved, five were slightly improved, and two remained unchanged. In 100% of these cases, immobilization of the involved interspace occurred within a year. The surgical technique is discussed.

We report the case of a 41-year-old man with an epidermoid carcinoma that had developed on a meningocele with a fistulous tract that chronically drained cerebrospinal fluid. After a review of the literature, we discuss the cause of this rare occurrence. We think that the recurrent discharge of spinal fluid (never complicated by meningitis) may have caused a chronic irritation of the tissues and then the delayed development of a carcinoma, which is similar to a case found in the literature. In our case there was a "flow" of carcinomatous cells along the fistula, which entered the meningocele, invading the subdural space as far as the peduncle. Our patient, who had a benign lesion (meningocele), came under neurosurgical care only after the lesion had degenerated. The malignant degeneration of such a benign lesion emphasizes the need for surgical treatment as soon as possible.

After a short review of the literature regarding aspergillosis, the authors report a case of a 7-year-old child suffering from cerebral aspergillosis with disseminated lesions. The authors emphasize the use of amphotericin B both intraventricularly and intravenously to obtain a longer survival when surgery is impossible because of the presence of multiple abscessual lesions in central nervous system. Authors' experience shows that the intraventricular administration of amphotericin B is well tolerated and does not cause collateral effects of the parenteral way.
The case of a woman with absence of neurological deficits, suffering from visual and auditory hallucinosis caused by a meningioma of the lesser sphenoidal wing, is described. The authors discuss the etiology of the hallucinosis that in the reported case is caused by an impairment of the deep temporal structures.
We report the case of a true aneurysm of the middle meningeal artery (MMA) associated with no other pathological findings. After a review of the literature, we emphasize that this case is not associated either with skull traumas, with vascular hypertension or with Paget's disease of the skull. Histological examination and neuroradiological findings confirm the suspicion that this is a case of true aneurysm of the middle meningeal artery.
