[Acute posterior multifocal placoid pigment epitheliopathy. A rare cause of ischaemic stroke]. | LitMetric

AI Article Synopsis

Article Abstract

Introduction: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is a rare inflammatory disease, generally of unknown aetiology, affecting the choriocapillaris, the pigment epithelium and the outer retina. It predominantly affects young patients and in some cases may involve the central nervous system in the form of strokes or meningoencephalitis. We report the clinical case of a young female with APMPPE that was complicated by stroke and intracranial hypertension.

Case Report: Our patient was a 16-year-old female who began with intense headaches suggesting intracranial hyper-tension, as well as with an acute deficit in the left hemisphere. A magnetic resonance scan of the head revealed embolic or vasculitic lesions in different territories. No evidence of meningoencephalitis was found in the cerebrospinal fluid analysis, but signs of associated intracranial hypertension were observed. The presence of very specific lesions in the posterior pole of the eye led to a diagnosis of APMPPE complicated by ischaemic stroke, probably caused by a vasculitic mechanism. An extensive aetiological study failed to identify a clear precipitating factor underlying the process. Treatment with corticoids was established, with good clinical and radiological progression.

Conclusions: APMPPE is an infrequent condition that generally has a good prognosis. In some cases, however, complications may arise owing to involvement of the central nervous system, and ischaemic stroke secondary to vasculitis is the most severe complication. In young patients with stroke who present visual symptoms and chorioretinital lesions, APMPPE must be considered in the aetiological diagnosis.
