✓ A 51-year-old woman became unconscious 19 hours after the onset of a headache. Computerized tomography disclosed an intracerebral hematoma in the left temporal lobe, with ventricular penetration. Angiography demonstrated the characteristic appearance of cerebrovascular moyamoya disease as well as an aneurysm-like shadow in the left temporal lobe, which proved on histological examination to be a pseudoaneurysm.

✓ Two patients with benign intracerebral cysts are reported and a brief review of the literature is given. Although computerized tomography (CT) scanning is useful in detecting a variety of intracerebral cysts, the CT findings are not specific for any lesion. An exploratory operation with establishment of an adequate route of drainage and a histological examination of the cyst wall are mandatory in the management of patients with a progressive but benign lesion.

✓ A 20-year-old woman presented with a 3-year history of intermittent focal headaches and a generalized seizure. Computerized tomography demonstrated a hypodense ring-enhancing cystic right parietal lobe lesion. At operation, a chocolate-colored cyst was excised which on histological examination proved to be endometriosis.

✓ Cerebral myiasis with a 10-day history of convulsions due to an intracerebral hematoma caused by a Hypoderma bovis larva is reported in an 8-year-old child. Computerized tomography (CT) showed the hematoma in a right parieto-occipital location. The H. bovis larva and the extensive intracerebral hematoma were discovered during surgery. Among human parasitoses, cerebral myiasis is rare: a review of the literature revealed only two reports, one published in 1969 and one in 1980. This is the first case that has been diagnosed as cerebral myiasis with exact identification of the Hypoderma bovis larva both from the CT scans and at surgery in a patient during life.

✓ A patient is reported who presented with manifestations of a space-occupying lesion in the left temporal lobe thought to be a metastasis, but on radiological examination and surgical exploration appeared to be a diffuse infiltrative glioma. Some 21 months earlier he had received a course of fast neutron therapy to a carcinoma of the left parotid gland. Diagnosis by microscopic examination revealed changes characteristic of delayed radiation necrosis.

✓ Two cases of cryptic vascular malformation that were not demonstrated by cerebral angiography were detected by computerized tomography. One of these patients had a cavernous angioma in the fourth ventricle with recurrent subarachnoid hemorrhages, and the other harbored a small arteriovenous malformation and intracerebral hematoma. The usefulness and limitations of computerized tomography in the identification of cryptic vascular malformations are discussed.

✓ The majority of patients with intracranial hemorrhage associated with moyamoya disease have been described as having subarachnoid hemorrhage (SAH), but it seems doubtful that moyamoya disease causes primary SAH. Computerized tomography (CT) has revealed that most of the hemorrhage found in cases of moyamoya disease is intracerebral or intraventricular. The authors have reviewed 54 cases of intracranial hemorrhage confirmed by CT, including nine of their own, and found that in all but one the bleeding was intracerebral or intraventricular. The single case of SAH was due to rupture of a saccular aneurysm associated with moyamoya disease. It may be concluded from these results that moyamoya disease does not cause primary SAH per se.

✓ The authors present the case of a 20-year-old woman with right-sided temporal intraparenchymal meningioma originating from underlying meningioangiomatosis. The patient manifested temporal-type seizures as the initial symptom. She had no stigmata of neurofibromatosis Type 2. Neuroradiological studies revealed an intraaxial, contrast-enhancing lesion in the right temporal lobe. After gross-total removal of the tumor, histological examination revealed a transitional meningioma with surrounding neural parenchyma and features of meningioangiomatosis. Although there were no signs of anaplasia, necrosis, or increased mitosis, tumor islands were observed in the adjacent neuropil. The rare association of meningioangiomatosis and meningioma is discussed, along with radiological and surgical findings.

✓ Eighty-two cases of cerebrovascular moyamoya disease were studied by cerebral angiography and computerized tomography. Occlusive lesions were demonstrated not only in the anterior circulation but also in the posterior circulation, and they were associated with the development of an abnormal vascular network (moyamoya vessels). Although occlusive lesions do occur in the vertebrobasilar system, the vertebrobasilar system also acts as a source of collateral channels to the anterior circulation in this disease.

✓ A case of craniopharyngioma originating in the sphenoid bone is presented. The tumor probably originated in the midline from epithelial cell rests along the path of the involuted craniopharyngeal duct. There was bone invasion and destruction of the floor of the middle fossa with intradural extension of tumor into the left temporal lobe. Survival from onset of symptoms was 37 years. Irradiation probably played a significant part in this patient's long survival. Modern techniques now in use might achieve cures with surgically unresectable intrasphenoidal craniopharyngiomas.
