초록
In contrast to well-known imaging findings of intracranial epidermoid cysts on magnetic resonance imaging, those of intracranial squamous cell carcinoma (SqCC) are relatively unknown. We present a case of coexistence of intracranial SqCC and epidermoid cyst, with consecutive follow up over 14 months. Based on our case, a solid enhancing portion adjacent to a typically-looking epidermoid cyst may become a clue for coexistence of intracranial SqCC. An initial contrast enhancement and/or heterogeneous signal on diffusion weighted imaging may become a useful diagnostic clue, but more importantly, sudden rapid growth is important in formulating diagnosis.
Abstract
In contrast to well-known imaging findings of intracranial epidermoid cysts on magnetic resonance imaging, those of intracranial squamous cell carcinoma (SqCC) are relatively unknown.

Based on our case, a solid enhancing portion adjacent to a typically-looking epidermoid cyst may become a clue for coexistence of intracranial SqCC. An initial contrast enhancement and/or heterogeneous signal on diffusion weighted imaging may become a useful diagnostic clue, but more importantly, sudden rapid growth is important in formulating diagnosis.
