OBJECTIVE
Arachnoid cysts are generally identified incidentally on brain imaging, although they occasionally cause symptoms because of expansion or bleeding. This study aims to describe patients in whom an arachnoid cyst was identified on magnetic resonance imaging (MRI) study performed for the
During the period from 1985 to 1992 we treated 43 patients with intracranial arachnoid cysts (ACs). In this retrospective study we assessed the outcome of these patients with regard to non-specific symptoms such as headaches and epileptic seizures. Twelve patients had headaches of obscure origin and
The causes of postural headache are usually associated with low intracranial pressure. However, there are still rare causes of posture-related headaches that are not associated with low intracraninal pressure and caused by pathologic processes. Herein, we report a patient with giant posterior
BACKGROUND
Headache is a common presenting complaint and has a wide differential diagnosis. Clinicians need to be alert to clues that may suggest an underlying secondary aetiology. We describe a novel case of headache secondary to intracranial hypotension which was precipitated by the rupture of a
Headache related with sexual activity (HAS) is a rare benign headache disorder. HAS is classified into pre-orgasmic and orgasmic headache. Increased intracranial pressure secondary to a Valsalva maneuver during orgasm has been proposed as a possible mechanism for orgasmic headache. We report a
Arachnoid cysts are commonly encountered when neuroimaging is obtained for headaches. Their clinical relevance is not always immediately clear and they may confound medical management.
UNASSIGNED
Arachnoid cysts are found everywhere in cerebrospinal axis, most often in the middle cranial fossa. They are very rare in prepontine location.

In this study, we report a 26-year-old female presenting with a 3-month history of headache and diplopia. On physical examination, she
We describe a diagnostic problem in a young adult with a long history of frequently occurring headache episodes. The cause for these episodes was traced to a rare condition, extensive arachnoid cyst of sphenoid sinus. Extensive lesions of the sphenoid sinus are relatively rare and can cause
To answer the question whether headache in association with a middle cranial fossa arachnoid cyst without other signs warrants surgery, an analysis of five cases is performed. Three of 5 patients became free of symptoms, compared with 15 of 19 (79%) patients that have been collected in the
We report a 34 year old male patient presenting with occipital headache and bilateral shoulder and neck pain. Cranial MRT discloses a large arachnoid cyst ventral to the medulla oblongata. The cyst displaces the caudal medulla oblongata dorsally to an angle of almost 90 degrees without causing
BACKGROUND
Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. However, symptomatic cases have been described, e.g. tumours, particularly pituitary adenomas, malformations, and infections/inflammations. The evaluation of cluster headache is
