Mucocele of the sphenoidal sinus is a rare lesion often mistaken for a pituitary tumour. A case first misdiagnosed as pituitary tumour is described. Additional radiography including CT findings led to the correct diagnosis. The treatment of sphenoidal mucoceles is surgical. The sublabial trans-septal route has proved to be an excellent approach.

Thirty-two patients with transitory ischemic attacks (TIA), 55 with cerebral infarction (minor stroke) and one with a disturbing bruise underwent carotid endarterectomy during a 4 year period. Within the first 2 weeks postoperatively, 10 patients (11%) had developed new neurological symptoms from the operated side. Two patients died postoperatively due to major stroke and 2 patients developed persistent neurological deficits, yielding a total operative mortality and permanent morbidity rate of 4.5%. In the other 6 patients, the neurological signs and symptoms disappeared completely within one month. During a follow-up for an average of 21 months, the only symptoms from the operated side were TIA in 2 patients, while 3 patients developed TIA and 5 infarctions from other vascular territories.

We report a patient who had raised serum and amniotic fluid alpha-fetoprotein levels at 16 weeks gestation. Ultrasonography revealed an apparently normal fetus and amniography displayed a soft tissue tumor in front of the fetus. The tumor turned out to be a placental haemangioma, when an apparently healthy girl weighing 2.88 kg was born at term.
The value of carotid angiography during operation in the surgical treatment of arteriovenous malformation is illustrated by 4 patients. After obliteration of the main supply to the malformation the blood may be redistributed to possible smaller feeding vessels now dilated and more clearly demonstrable than preoperatively. In some cases, angiography both preoperatively and during operation may be needed for a demonstration of the whole malformation with all its feeding vessels. Angiography during operation reduces the need for postoperative angiography.
Preliminary experiences of computed tomography of the head are reported in a material of 213 patients. The majority of examined lesions includes intracranial tumours and cerebrovascular lesions.
A radiologic method for assessment of the patency of ventriculo-atrial shunts is described together with a safe technique for gas encephalography of patients with ventriculo-atrial shunt. Despite discontinuity the shunting system may be functioning.
Computer tomography has been applied in a material of six patients meeting the criteria for cerebral death. The primary intracranial pathology, haemorrhages, infarction and contusions were demonstrable. No generalized reduction of the attenuation characteristic of infarction was found in spite of angiographic arrest of the intracranial circulation. Compression and obstruction of small brain vessels may in some cases be the primary cause of arrest of the brain circulation in cerebral death and not an increase of the intracranial pressure to levels approaching or surpassing the mean systemic arterial pressure.

One hundred seventeen patients, 31 with TIA and 86 with cerebral infarction, had angiographically verified atherosclerosis within the relevant carotid artery territory and normal CSF. They were treated with anticoagulants for a mean of 11.1 months. No TIA but 1 cerebral infarction, appearing during inadequate anticoagulant therapy, was registered. Seventy-six of the patients, 20 with TIA and 56 with infarction, were followed for a mean of 4.4 months after cessation of anticoagulants or during inadequate antinecessitating re-institution of anticoagulant therapy. Long-term, anticoagulant treatment can be recommended in carefully selected patients with TIA, and also with infarction in the carotid territory.
