Abstract

Introduction The pineal gland is a common location for intracranial germ cells, but dermoids are not commonly observed in this area. In the present paper, we discuss the clinical and radiological features as well as the treatment and outcome of this cyst in a 6-year- old child with a pineal dermoid cyst.

Case Presentation The patient presented with chronic headache 6 months before admission in 2018. On the first admission, an enhanced lesion with a small cyst was detected in brain imaging. Magnetic resonance imaging (MRI) of the brain at follow-up (2 months after the first presentation) showed enlargement of the cyst size with compression on the adjacent structures. Radical excision of the tumor was performed after the endoscopic biopsy due to pressure exerted on the adjacent structures.

Conclusion Dermoid cyst should be considered as a differential diagnosis for enhanced lesions of the pineal region.

Resumo

Introdução A glândula pineal é uma localização comum para as células germinativas intracranianos, mas dermoids não são frequentemente observados nesta área. No presente artigo, discutimos as características clínicas e radiológicas, bem como o tratamento e a evolução desse cisto em uma criança de 6 anos com cisto dermóide pineal.

Apresentação do caso O paciente apresentou cefaleia crônica 6 meses antes da admissão em 2018. Na primeira admissão, uma lesão acentuada com um pequeno cisto foi detectada na imagem do cérebro. A ressonância magnética (RM) do cérebro no seguimento (2 meses após a primeira apresentação) mostrou aumento do tamanho do cisto com compressão das estruturas adjacentes. A excisão radical do tumor foi realizada após a biópsia endoscópica devido à pressão exercida nas estruturas adjacentes.

Conclusão O cisto dermóide deve ser considerado um diagnóstico diferencial para lesões acentuadas da região pineal.
