[Non-aneurysmal subarachnoid hemorrhage: 60 cases].

INTRODUCTION: Spontaneous subarachnoid hemorrhage (SAH) is idiopathic in 15% of cases. They represent a group whose characteristics are different from those with an aneurysmal etiology. We present a retrospective longterm follow up of 60 patients, analyzing symptomatology, complications and evolution and identify a subgroup of patients with a perimesencephalic pattern (PMP) in computed tomography (CT) for their excellent prognosis. METHODS: We collected information on 60 patients admitted to our center between 1992 and 2000 and divided them into three groups, according to neuroimage: 26 had a PMP, 28 showed an aneurysmal pattern (AP), and 6 patients had normal TC, with complete arteriographic study. Length of follow-up was 6-24 months. RESULTS: All of the 26 patients with SAH and PPM pattern were rated grade I-II on the Hunt-Hess scale. None of them had complications during hospital stay and at long term, 22 (84%) were asymptomatic, while 4 (16%) reported cephalea. Out of 28 patients with SAH and AP, 22 were rated Hunt-Hess Scale grade I and II (78%), 5 grade III (18%) and one patient was rated grade IV. Rebleeding caused death in one of them, and two required drainage for hydrocephalia. A total of 68% (19 patients) were asymptomatic and the others complained of cephalea. CONCLUSIONS: We stress the good evolution of nonaneurysmal SAH at short and long term, especially those following a PMP with absence of complication.

[The involvement of the parenchyma of the central nervous system in Behçet disease].

INTRODUCTION: Behçet disease is a systemic form of vasculitis which presents with neurological symptoms with a frequency varying between 16 and 40%. Involvement of the parenchyma has been found to worsen the prognosis in patients with neuroBehçet (NB). OBJECTIVE: To review the clinical features and course of patients with NB involving the parenchyma of the central nervous system (CNS). CLINICAL CASES: Seven patients with Behçet disease and neurological localizing signs were seen in our hospital between 1989 and 1996. The initial diagnosis was of ischemic ictus in five of the seven patients. Both neuroimaging studies and investigation of the cerebrospinal fluid were always pathological in all cases. Vascular studies (arteriography and echo-Doppler of the supra-aortic trunks) were normal. One patient died. Four patients had serious sequelae following treatment. CONCLUSION: NB should be included in the different diagnosis of ictus. Involvement of the parenchyma of the CNS was accompanied by lymphocytic meningitis, perhaps also leading to a worse functional prognosis.

[Purely bulbar hematomas].

INTRODUCTION: Purely bulbar hematomas are not common (0.25%-0.50% of all intraparenchymatous hematomas), probably because of the particular characteristics of the anatomy and hemodynamics of the bulbar circulation. CLINICAL CASES: We selected 18 cases. Three of these were our own and the purely bulbar localization was confirmed by neuroimaging surgical findings and necropsy. Its appearance was related to arterial hypertension, anticoagulant treatment and obvious or occult vascular malformations, although in a considerable proportion (39%) no cause was found. Although arterial hypertension is less important in its etiopathogenesis as compared with other sites of intraparenchymatous hemorrhage, 7 of the patients were hypertensive. The commonest clinical findings were nystagmus (72%), and dysphagia and hypoglossal paralysis (61%). The commonest site was posterior. Arteriography was of little use since this was normal in all the cases in which it was done (72%). The presence of angiographically occult malformations made it advisable to use magnetic resonance and repeat this after the acute phase. Three quarters of the patients were treated medically. Mortality (22%) was lower than the overall rate for posterior fossa hematomas, and the prognosis was better since no survivors had incapacitating sequelae. CONCLUSION: The specific etiopathogeneses, clinical characteristics and course of bulbar hematomas makes it advisable to do a differential study regarding other types of intracerebral hemorrhage.
