DELAYED DIAGNOSIS OF AVM PRESENTING WITH STROKE AND SEIZURES IN A YOUNG NIGERIAN: A CASE REPORT.

BACKGROUND

Brain arteriovenous malformations (BAVM) are a cause of intracerebral haemorrhage (ICH) and seizures especially in young patients. ICH due to BAVMs seem to have relatively better neurologic outcomes compared to other causes of spontaneous ICH as patients often recover fully. In this report we highlight a case of delayed diagnosis of BAVM in a young man who presented with seizures and stroke.

CASE SUMMARY

A 36-year-old man was referred on account of focal, secondarily generalized tonic clonic convulsions. He had suffered a right ICH 3 years before the index presentation. His general physical and neurologic examination were normal. Electroencephalography revealed right sided focal epileptiform discharges and brain MRI revealed a right parieto-occipital AVM. The seizures were controlled with carbamazepine and he was referred for neurosurgical evaluation.

CONCLUSION

BAVMs are an important cause of intracerebral haemorrhage and attendant neurologic morbidity especially in young individuals. Neuroimaging plays a central role in BAVM diagnosis and MRI is of great value where facilities and expertise for conventional angiography do not exist. In some instances, delayed presentation of BAVM cases may be due to relatively better neurologic outcomes in BAVM-related ICH.
