The neck hump, also called buffalo hump, is a postural change that develops in the dorso-cervical area due to different causes such as postural issues, some of diseases, medications, obesity and genetic factors.

Clinically Relevant Anatomy[edit | edit source]

Posterior and Side Views of the Neck

The posterior region of the neck predominantly includes subcutaneous fat and skeletal muscle. [1]

See the page of the cervical anatomy or more pages on the cervical anatomy category for understanding more.

Aetiology[edit | edit source]

  1. Cervical Lipodystrophy: Refers to a metabolic change seen in HIV-infected patients receiving highly active antiretroviral therapy. Due to lipohypertrophy, localized abnormal fat accumulation may occur in the dorso-cervical area. [2]
  2. Dowager’s Hump: It refers to the curvature with a Cobb angle of more than 40 degrees in hyperkyphosis. [3] It can be due to muscle weakness or sensory deficits [4] and if left untreated can lead to functional limitations, increased risk of falls and vertebral fractures, and low quality of life. [3]
    Buffalo hump is one of the signs of Cushing's Syndrome.
  3. Cushing's Syndrome: One of the signs of this syndrome is supraclavicular/dorsocervical fat pad (buffalo hump) with a prevalence rate of 50%. [5]
  4. Madelung's Disease: Also known as Launois-Bensaude Syndrome [6], is a rare disorder of adipose metabolism and refers to multiple, symmetrical lipomatosis / benign symmetric lipomatosis. [7][8] Nonencapsulated lipomas (fatty masses) can present in different parts of the body, including the neck. [9]
  5. Osteoporosis: One of the clinical symptoms of osteoporosis in older adults is dowager’s hump. [10]
  6. Obesity: A study [11] showed a meaningful difference between the obese and control group with more cases of adipomastia, and buffalo hump seen in the obese group.
  7. Genetics: Although any specific gene to cause buffalo hump has not been declared, it is known that some people may have a genetic predisposition to obesity and fat accumulation in certain areas of the body, thus having buffalo hump.
