What syndrome is characterized by weak upper extremity pulses, fever, night sweats, arthritis, myalgias, skin nodules, and ocular disturbances in females under 40 years old?

The syndrome described in the question is Takayasu Arteritis, which is an inflammatory condition that primarily affects women under the age of 40. One of the hallmark features of Takayasu Arteritis is the presence of weak upper extremity pulses due to involvement of the aorta and its major branches, leading to stenosis and decreased blood flow to the arms.

Additionally, the systemic manifestations such as fever, night sweats, and myalgias are common in inflammatory diseases. Arthritis and skin nodules can also occur as manifestations of systemic inflammation. Ocular disturbances may result from the involvement of the carotid branches, which can affect blood supply to the eyes.

Takayasu Arteritis is often associated with these clinical features, making it the most fitting diagnosis in this context for a female patient under 40 presenting with such symptoms.
