[A prospective study of subarachnoid hemorrhage in Navarra].

The authors evaluate subarachnoid hemorrhage (SAH) in the autonomous community of Navarra during 3 years. Ninety-five patients were evaluated (mean age (MA) 51.47 years). They were divided in groups depending on angiographic findings. Thirty-four had an intracranial aneurysm (MA 5%.23 years) with a female preponderance (66.7% vs 33.3%). Eight patients had an arteriovenous malformation (AVM) (MA 33.7 years); in 35 patients the angiographic study was negative (MA 44 years) and in 18 angiography was not carried out (MA 66.66 years). Computed tomography was positive in 40% of patients and there was a correlation between the amount of blood in the cisterns and poor outcome of patients after 6 months. In the discussion, the authors emphasize the high incidence of SAH without angiographic findings.

Computerized tomography in primary hyperammonemia.

Urea cycle enzymopathies are rare in the literature. They are accompanied by neurological disorders somehow related to the increase in blood ammonia. Reviewing the possible physiopathological course we present a case in which during an eight month period severe cerebral atrophy developed, more intense in the occipital region but totally sparing the posterior cranial fossa structures.

[Cystic pancreatic tumours and pseudo-tumoural lesions].

Cystic lesions of the pancreas are infrequent, estimated at only some 1% of all pancreatic tumours and at some 10% of all pancreatic cysts. The pre-operational diagnosis is important for a suitable treatment, with valuable radiological techniques available today such as ultrasound, computerised tomography and magnetic resonance. In spite of this we have to accept that we are facing a group of tumours whose diagnosis is difficult, due to the great variety of cellular types existing within them.
