    Notes: Abstract We present a case involving a microsurgical approach to solving the problem of a medical cerebral artery (MCA) occlusion occuring after GDC coiling of an internal cerebral artery (ICA) bifurcation aneurysm in a 40 year old woman. We describe the clinical course of the case and discuss technical possibilities and risks of clipping a coiled aneurysm. One key to success is awareness of changes in the aneurysm's properties after coiling. With loss of elasticity the aneurysm had the effect of a tumor fixed on the vessel. The apposition of the aneurysm to the wall of the vessel, as well as the aneurysm's rigidity and increase of intracranial pressure after subarachnoideal hemorrhage (SAH), may lead to occlusion of the vessel. In cases of an mandatory operation due to the occlusion of a main arterial stem after coiling, it is primarily crucial to perforate the aneurysm's fundus, remove the coils, and, finally, to clip the slack neck of the aneurysm. An attempt to precisely prepare and clip the aneurysmal neck without removing the coils could result in the rupture of the aneurysm's neck.

    Notes: Abstract We describe the case of a 16-year-old boy with idiopathic hydrocephalus, who developed cranial subdural hygromas and subsequent cranial subdural hemorrhage after a shunting procedure. Sciatica and radicular lumbar pain initially seemed to be unrelated to the preceeding implantation of a ventriculoatrial shunt. CT scan revealed a sharply demarcated hyperdensity in the lumbar subdural space with compression of the cauda equina. Differential diagnosis considerations included vascular malformations, vascular tumors, benign tumors of meninges or nerve sheets, ependymoma, lymphoma, and metastases. MR investigation did, in fact, clearly recognize this hyperintense space-occupying lesion as blood in the subdural space which outlined the cauda equina. We believe that the spinal subdural hematoma in our case represented an extension of intracranial subdural haemorrhage fluid into the spinal subdural space.

    Notes: Abstract Our report describes the uncommon case of a 61 year old female patient who underwent a left parietooccipital craniotomy and extirpation of a malignant tumor. Histological examination revealed a metastatic carcinoma of mammary origin intimately intermingled with a calcified oligodendroglioma WHO II. The preexisting oligodendroglial part had been detected four years before, but since then had been misinterpreted as a glious scar resulting from a previous brain trauma. Three years before neurosurgical intervention, the patient had undergone a left side mastectomy. The histological finding at that time was a solid breast tumour WHO T1N0. The occurence of cerebral mixed neoplasias and possible causal factors are discussed.
