Tolosa-Hunt syndrome
Tolosa-Hunt syndrome (THS) is a rare disorder characterized by severe and unilateral headaches with extraocular palsies, usually involving the third, fourth, fifth, and sixth cranial nerves, and pain around the sides and back of the eye, along with weakness and paralysis (ophthalmoplegia) of certain eye muscles.

Tornwaldt cyst
A Tornwaldt cyst is a benign cyst located in the upper posterior nasopharynx.
It can be seen on computed tomography (CT) or magnetic resonance imaging (MRI) of the head as a well-circumscribed round mass lying in the midline. Read more…
Neurodegeneration
Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons.
Many neurodegenerative diseases including Parkinson’s, Alzheimer’s, and Huntington’s occur as a result of neurodegenerative processes. As research progresses, many similarities appear which relate these diseases to one another on a sub-cellular level. Read more…

Cerebral arteriovenous malformation
A cerebral arteriovenous malformation (AVM) is an abnormal connection between the arteries and veins in the brain.
An AVM diagnosis is established by neuroimaging studies after a complete neurological and physical examination.
Three main techniques are used to visualize the brain and search for AVM: computed tomography (CT), magnetic resonance imaging (MRI), and cerebral angiography. Read more…

Pinealoma
Pinealoma is a tumor of the pineal gland.
The pineal gland produces the hormone melatonin which plays a role in regulating circadian rhythms.
A pinealoma may disrupt production of this hormone, and insomnia may result. Read more…
Cerebrospinal fluid
Cerebrospinal fluid (CSF), Liquor cerebrospinalis, is a clear, colorless, salty bodily fluid, that occupies the subarachnoid space and the ventricular system around and inside the brain and spinal cord. In essence, the brain “floats” in it. Read more…

Optic nerve sheath meningioma
Optic nerve sheath meningiomas (ONSM) are rare benign tumors of the optic nerve. 60–70% of cases occur in middle age females, and is more common in older adults (mean age 44.7 years). It is also seen in children, but this is rare. The tumors grow from cells that surround the optic nerve, and as the tumor grows, it compresses the optic nerve. This causes loss of vision in the affected eye. Rarely, it may affect both eyes at the same time. Read more…
