RESUMO
Arachnoid cysts are extra-cerebral, intra-arachnoidal cerebrospinal fluid collections - the most frequent congenital developmental intracranial cystic lesions. They are often diagnosed incidentally during imaging exams acquired for different reasons, and are usually asymptomatic. Rare complications are post-traumatic rupture with consequent subdural haematomas. Spontaneous bleeding should be acknowledged as a rare but possible complication of this benign lesion. We report on the case of a patient presenting with a giant arachnoid cyst extending to the left frontal, temporal and parietal lobes associated with acute subdural haematoma without history of trauma.

To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history. Computed tomography and magnetic resonance scans supposed the presence of an abscess caused by a foreign intraorbital body, confirmed by surgical findings.
