Case Reports
An association between cerebral aneurysm re-bleed and CT angiography--more than a coincidence?
Rupture of cerebral aneurysm during CT angiogram is a rare occurrence. Here we present such a case where an aneurysmal re-rupture during CT angiogram was demonstrated.

We describe the case of a 29-year-old farmer who developed upper limb radiculopathy followed by myelopathy in his lower limbs. MRI findings suggested cervical disc prolapse with cord changes. Despite a successful anterior cervical decompression and fusion his symptoms rapidly returned. Further investigations ultimately diagnosed underlying neurosarcoidosis.

Tumours in the petroclival region have been a challenge to neurosurgeons. We present a cohort of 24 patients with petroclival meningioma (PCM) and trigeminal schwannoma (TS) in the petroclival region with extension to the middle fossa which were removed with the temporal base intradural transpetrosal (TBIT) approach. ⋯ Surgical strategy for PCM and TS in the petroclival region should be tailored to individual patients. The TBIT approach may improve the exposure of tumours in the petroclival region. A clear description of the 'safe area of intradural petrosectomy' appears to decrease the risk associated with petrosectomy procedure in the TBIT approach.

We report two cases of cervical spondylotic myelopathy (CSM) with extensive T2-weighted intramedullary changes noted on preoperative imaging extending far beyond the level of compression. A delayed resolution 2 years after cervical oblique corpectomy was noted in both cases. This short report cautions against diagnosing this unusual magnetic resonance imaging (MRI) finding as an intramedullary tumour, demyelination or an inflammatory process.
