First reported case of hydrocephalus in jointly diagnosed bacterial meningitis and a colloid cyst: how Ockham's razor became Hickam's dictum.

We report the first case in the literature of acute hydrocephalus due to a simultaneous diagnosis of bacterial (not asceptic) meningitis and a colloid cyst. Diagnosing disease is the cornerstone skill of a medical practitioner. Both education and experience allow for sharpening of this skill throughout years of medical practice.

Spinal paraganglioma presenting with raised intracranial pressure: a note on the diagnosis and post-operative management.

Background: Spinal paragangliomas are tumors of neuroendocrine origin that present with symptoms of mass effect or neurosecretion but rarely involve the central nervous system. Raised intracranial pressure and papilledema are therefore unusual presentations of a spinal paraganglioma.

Methods: We review the case of a 54-year-old man who presented with headache and visual disturbance.
