Tumors of the cerebellopontile angle; considerations on 10 cases

Cerebellopontine angle tumor

Cerebellopontine angle (CPA) lesions account for up to 10% of all intracranial tumors.

Types

The most common CPA lesions are vestibular schwannomas (70-80%), meningiomas (10-15%) and epidermoid cysts (5%). CPA tumors are estimated to be the secondary cause for up to 9.9% patients with trigeminal neuralgia.

First use of fluorescein sodium guided resection

Fluorescein sodium guided resection

The first use of fluorescence for brain tumour surgery was in 1948 by G.E. Moore 1) using fluorescein sodium, a strongly fluorescing and non-toxic agent.

First description of Parsonage-Turner Syndrome

The Parsonage Turner syndrome is named after Maurice Parsonage and John Turner and published in the Lancet by Parsonage and Turner .

The condition, subsequently coined Parsonage-Turner Syndrome, had been previously described in the literature as far back as 1897 with many similar clinical presentations of the syndrome reported prior to the extensive study of the syndrome by Parsonage and Turner.
Parsonage Turner syndrome is also known as acute brachial neuropathy and acute brachial radiculitis.
Other names used are Parsonage–Aldren–Turner syndrome, neuralgic amyotrophy, brachial neuritis, brachial plexus neuropathy, or brachial plexitis.
