ABSTRACT: Background: Rare pathological conditions are frequently a diagnostic challenge in intensive care. Posterior-reversible encephalopathy syndrome (PRES) is a clinical and imaging diagnosis recently individualized. It occurs in various conditions such as collagenosis or vasculitis of the central nervous system, electrolytic disorders and the use of cytotoxics or immunosuppressive treatment. It is responsible for non-specific neurological manifestations such as confusion, coma, convulsions or visual disturbances. The diagnosis is suggested by brain magnetic resonance imaging (MRI). The lesions correspond to vasogenic edema and are therefore generally reversible after etiologic treatment and control of blood pressure. Aim: This clinical case aims to show the diagnostic complexity of rare pathologies in the intensive care unit. Case presentation: We present a case of a 14-year-old child received in the pediatrics department for generalized tonic-clonic convulsions with tongue biting in a febrile context. Malaria was negative, with hyperleukocytosis, slightly elevated C-reactive protein, anemia and hypokliemia, lumbar puncture was performed and all cerebrospinal fluid examinations revealed nothing. The seizures were controlled by titrated cumulative doses of diazepam with a total of 12mg, antibiotic therapy with ceftriaxone, corticotherapy with dexamethasone 12mg and blood transfusion without any improvement in his condition. He was then transferred to intensive care where the clinical and paraclinical assessment highlighted a neurological deficit Glasgow coma scale of 12/15 and biological hyponatremia. Brain CT-scan was normal. Hydroelectrolytic equilibration was undertaken, antibiotics continued, anti-comital prophylaxis and general resuscitation measures were provided. He regained consciousness on the 3rd day. On the 4th day, he presented high blood pressure and on the 5th, a resumption of convulsions without any obvious biological disorder, cerebrospinal fluid control was once more non-pathological. An MRI was performed and revealed Posterior-reversible encephalopathy syndrome. Conclusion: Posterior-reversible encephalopathy syndrome is a rare disease. It is necessary to keep rare diseases in mind.
