Signs and symptoms may include: [8]
Physical rectal examination, high-resolution X-rays and MRI scans can rule out various causes unrelated to the coccyx, such as Tarlov cysts and pain referred from higher up the spine. Note that, contrary to most anatomical textbooks, most coccyxes consist of several segments: 'fractured coccyx' is often diagnosed when the coccyx is in fact ...
Some cysts in the CNS can be asymptomatic (producing or showing no symptoms), depending on their location in the brain or spinal cord. If the cysts develop in critical areas of the central nervous system, they can present one or more of the following symptoms: [6] Pressure in the spinal cord or brain Rupture of nerves around the cyst
There are four types of ovarian cysts — functional cysts, PCOS cysts, benign ovarian tumor and malignant ovarian tumor — that range from harmless to fatal.
Moderate-to-severe cases can cause radicular pain in the legs caused by nerve root compression. [5] The symptoms are usually exacerbated by upright posture and often, but not always, relieved by lying down. Postural headaches can be related to spontaneous spinal cerebrospinal fluid leaks.
