“…Lack of signal suppression on a fluid-attenuated inversion recovery (FLAIR) sequence, high signal intensity on diffusion-weighted imaging (DWI) and hypointensity on ADC maps are the most relevant MRfeatures and help eliminate diagnostic uncertainty. 9 Hypointense signal on ADC maps seen in this patient is due to motion restriction of proton within the cyst. 6 Macroscopically, epidermoid cysts are usually located intradurally.…”

Posterior Fossa Intradiploic Epidermoid Cyst: A Case Report

Epidermoid cysts are rare, benign congenital tumours of ectodermal origin which typically present between the third to fifth decade. These tumours comprise approximately 0.2-1.8% of all intracranial tumours. Though these pearly tumours are potentially curable, subtotal resection may lead to catastrophic complications such as recurrence, granulomatous meningitis and carcinomatous degeneration of cyst wall. We herein report the case of a 36-year-old man who presented with an unusual mixed density posterior fossa epidermoid cyst on imaging studies. Total removal not only cures both tumour and seizure attack in this case but also preserves patient’s neurological function.

“…Após injeção de contraste pode ter um reforço fino na periferia da lesão, provavelmente devido à inflamação perilesional ou transformação maligna 16,33 . O exame de RM nas sequências de densidade FLAIR e por difusão, tem papel importante no diagnóstico diferencial, na avaliação pré-operatória e no seguimento pós-operatório 4,33 .…”

O cisto epidermoide é um tumor congênito benigno e originário do ectoderma. Ocorre na terceira e quinta década de vida. Corresponde aproximadamente a 0,2 a 1,8% dos tumores intracranianos. A forma de cisto epidermoide intradiploico é considerada rara. Ocorre mais nos ossos occipital, parietal e frontal. Raramente apresenta degeneração maligna. O tratamento ideal é exérese total e cursa com bom prognóstico. Os autores descrevem um caso de cisto epidermoide intradiploico gigante localizado no osso occipital, associado à síndrome cerebelar, submetido à exérese total, apresentando bom prognóstico

Intradiploic inclusion cysts are exceedingly rare in the pediatric population. The authors present a 16-year-old male patient who presented with a large growing calvarial mass with a preoperative diagnosis of fibrous dysplasia based on radiologic imaging. Craniectomy followed by autogenous reconstruction was performed. Histopathological examination revealed a relatively small inclusion cyst of the intradiploic space, surrounded by reactive bone. This patient demonstrates a highly unusual presentation of a rare entity, and the authors discuss the diagnosis and management of intradiploic inclusion cysts.
