Pseudotumor cerebral associado ao uso de ciclosporina após transplante renal / Pseudotumor cerebri associated with cyclosporin use following renal transplantation

Pseudotumor cerebral (PC) é uma síndrome, caracterizada pela presença de hipertensão intracraniana (HIC) e sistema ventricular normal. Pacientes submetidos a transplante renal parecem ser mais suscetíveis a desenvolvê-la. devido á terapia com imunossupressores. Ciclosporina (CsA) é uma causa rara de PC, pouco descrita na literatura e que deve ser lembrada no diagnóstico diferencial de HIC e papiledema nesses pacientes. relatamos um caso de um menino de 10 anos, há três anos com enxerto renal, em uso crônico de micofenolato mofetil (MMF), CsA e baixas doses de prednisona que apresentou quadro de cefaléia, vômitos, diplopia e fotofobia. Fundoscopia revelou edema de papila bilateral. Exame do líquor (LCR) e de imagem foram normais. Após exclusão de causas secundárias, foi feito diagnóstico de PC devido ao uso crônico de CsA, que, portanto, foi substituída por Sirolimus. O paciente apresentou melhora clínica progressiva, com resolução do papiledema após três meses.

Pseudotumor cerebri (PC) is a syndrome characterized by the presence of intracranial hypertension (ICH) and normal ventricular system. Patients undergoing renal transplantation appear to be more susceptible to developing it. due to immunosuppressive therapy. Cyclosporine (CsA) is a rare cause of CP is rarely described in literature and should be considered in the differential diagnosis of ICH in these patients and papilledema. report a case of a boy of 10 years, three years ago with renal graft in chronic use of mycophenolate mofetil (MMF), CsA and low doses of prednisone who developed headache, vomiting, diplopia and photophobia. Fundoscopy revealed bilateral optic disc edema. Examination of cerebrospinal fluid (CSF) and imaging were normal. After exclusion of secondary causes, was diagnosed with PC due to chronic use of CsA, which was therefore replaced by sirolimus. The patient presented progressive clinical improvement, with resolution of papilledema after three months.

[Pseudotumor cerebri associated with cyclosporin use following renal transplantation].

Pseudotumor cerebri (PC) is a syndrome characterized by the presence of intracranial hypertension (ICH) and no alteration in the ventricular system. Renal transplanted patients seem more susceptible to develop it due to immunosuppressive therapy. Cyclosporin (CsA) is a rare cause of PC, scarcely reported in the literature, and should be considered in the differential diagnosis of ICH and papilledema in those patients. We report the case of a 10-year-old boy, with a renal allograft for three years, on chronic use of mycophenolate mophetil (MMF), CsA, and low doses of prednisone. The patient presented with headache, vomiting, diplopia, and photophobia. Funduscopy showed bilateral papilledema. Cerebrospinal fluid analysis and imaging tests were normal. After excluding secondary causes, PC was diagnosed based on the chronic use of CsA, which was then replaced by sirolimus. After that, the patient progressively improved, and the papilledema resolved in three months.
