Objective: Evaluation of the UK NEQAS 2008 guidelines for the interpretation of spectrophotometric xanthochromia. Method: A search of the laboratory database for all the xanthochromia test results between May 1st 2008 and May 1st 2009 was performed. Medical charts were reviewed for patients of Hôpital de l’Enfant-Jésus (HEJ) that had at least one detectable pigment (bilirubin, oxyhemoglobin, or methemoglobin). Xanthochromia results obtained with 4 different criteria (Chalmers original, Modified Chalmers, Duiser and UK NEQAS 2008) were compared. Results: We reviewed 41 medical charts (2 patients with duplicate lumbar punctures (LP) for a total of 43 LP). For these 41 patients there were 11 positive xanthochromia results, 5 of which were in concordance with a final diagnosis of subarachnoid hemorrhage (SAH). The diagnosis of the 6 other positive xanthochromia results were as follow: meningeal spread of a lymphoma, cerebral amyloid angiopathy, exertional headache, viral encephalitis with a possibility of petechiaes on the cerebral CT and second LP. Interpretation (negative/positive) of 40/43 LP was identical for the 4 methods. 2 LP were positive with Duiser and UK NEQAS 2008 but negative with Chalmers approaches (final diagnosis: SAH and cerebral amyloid angiopathy). 1 LP was positive only by the Duiser method (viral encephalitis). Conclusions: UK NEQAS 2008 guidelines identified all SAH but are sensitive to traumatic and pathologic meningeal lesions. Except for a case of viral encephalitis with a suspicion of cerebral petechiaes on CT, UK NEQAS 2008 gave xanthochromia results similar to the one in use at HEJ (Duiser). Chalmers original and Modified Chalmers methods missed one of the five SAH.

The present article addresses the definition of cerebral amyloid angiopathy (CAA) and its symptoms based on the analysis of the medical case; the issues of diagnosis and treatment of this pathology are discussed. The Boston criteria, which became the basis for diagnosis, study of clinical manifestations and progression of CAA and approaches to its therapy, are presented. Methods and modes of neuroimaging, including magnetic resonance imaging (MRI), which verify micro cerebral haemorrhage, are described. At the same time, the role and significance of cardiac arrhythmias in the genesis of ischemic stroke are discussed, and scales for assessing the risk of its occurrence are presented. The observation of the neurological, somatic, neuroimaging, neuropsychological status of a 62-year-old patient confirms quite rare combination of probable CAA, paroxysmal atrial fibrillation and repeated hemorrhagic functional apoplexy (FA). The relevance of the case described, is a complex clinical dilemma based on mutually exclusive recommendations for the pharmacological correction of such conditions. It is emphasized that in many multicenter clinical studies on the effectiveness of antithrombotic medication (antiaggregants, anticoagulants) in the treatment and prevention of ischaemic functional apoplexy , an important exclusion criterion is a hemorrhagic stroke in past history (including the multiple changes in haemostasis indicators). Taking into account the obtained clinical and laboratory data in the dynamics, the tactics of treating the described patient were determined. The results of studies related to the treatment of comorbid pathology that should become the subject of the development of a personalized algorithm for managing patients in each specific case, are discussed.

We report the case of long-term follow-up of brain magnetic imaging of cerebral amyloid angiopathy. Cerebral amyloid angiopathy is often considered a major cause of spontaneous intracerebral hemorrhage in the elderly. This case illustrates the markedly progressive clinical and radiological features of the vasculopathic process in 10 years.
