RESUMEN
This report presents the imaging appearances of an uncommon case of intradiploic frontal bone aneurysmal bone cyst (ABC) in a 10-year-old girl. ABCs are rare in the calvarium. The radiological and aetiopathological differences between the more commonly occurring ABCs of the long bones and vertebrae, and their rarer counterparts in the calvarium and facial bones, have been discussed. Unique also to this case is the reconstruction performed using the outer table of the bone flap after excising the tumour.

A 50-year-old female presented with a right acoustic schwannoma colocated with a cerebellopontine angle arachnoid cyst. The arachnoid cyst was distinct from the arachnoid cap surrounding the acoustic schwannoma. Initial excision of the arachnoid cyst created the space required to excise the schwannoma. The acoustic schwannoma had surprisingly dense adhesions to the brainstem, probably due to the constant pressure exerted by the cyst displacing the tumor towards the brainstem. The acoustic schwannoma was excised by meticulous dissection. Such a coexisting lesion should be suspected when a large cystic collection surrounds an acoustic schwannoma. Initial excision of the arachnoid cyst will prevent excessive cerebellar retraction.

This is a case of Aspergillus infection in a twenty year old male presenting as an insidiously growing intradural spinal cord tumour with signs of cord compression. There was no definite portal of entry and the patient had no signs of immunsuppression. It is believed that such a case has not been previously reported. The lesion resembled a benign tumour on preoperative imaging and intraoperative consistency and vascularity. The lesion was successfully and completely resected. MR images of this unusual lesion are presented.
