The pain and dysfunction associated with a loss of innervation by the spinal accessory nerve has motivated surgeons to modify the classic radical neck dissection. A prospective study of 109 patients who underwent either a radical neck dissection or a modification of it with preservation of the spinal accessory nerve revealed that those patients in whom the nerve, muscle, and vein were preserved had less dysfunction (30 percent) than those with nerve preservation only (50 percent) or classic radical neck dissection (60 percent). In addition, even when the functional disability was the same, there was less associated pain with nerve-sparing procedures. Furthermore, a large group of patients (40 percent) who underwent classic radical neck dissection had minimal disability. Given these results, a prospective study of recurrence data in these patients is indicated.

Background: Occult papillary thyroid carcinoma (PTC) refers to the PTC accidentally found due to its occult lesions. Classic, as the most common subtype of PTC, is usually considered to have a low degree of malignancy and a favorable prognosis. Currently, the American Thyroid Association Management Guidelines adopted active surveillance (AS) as an alternative to immediate surgery in some low-risk PTC patients with less than 1 cm in diameter.

NUT carcinoma is a rare, aggressive malignancy characterized by chromosomal rearrangements involving the NUTM1 gene. We present the case of a 47-year-old male with a history of hypertension, diagnosed with NUT carcinoma originating in the ethmoid sinus and accompanied by extensive neck metastases. The patient underwent a left modified radical neck dissection and endoscopic nasal tumor excision, followed by concurrent chemoradiotherapy.

A 36-year-old woman with a history of neck swelling was diagnosed with papillary thyroid carcinoma, a common but typically slow-growing thyroid cancer with a good prognosis. Despite frequent lymph node metastasis, mortality rates are low. This cancer can rarely spread to unusual areas like the axillary region.

Aneurysms of the middle cerebral artery (MCA) account for up to 40% of all unruptured intracranial aneurysms [1-3] and 14% to 20% of ruptured ones. [4-5] Giant MCA aneurysms are rare, representing 10% of cases [6], but carry an aggressive natural history, with the UCAS Japan study reporting an annual rupture rate of ∼ 17%. [7].
