Brain contusion (bruise) is a type of intracerebral hemorrhage (bleeding within the brain tissue itself) and common in the setting of traumatic brain injury (TBI).
The pituitary gland is a small gland that sits in the sella turcica, a saddle-shaped depression located in the bone at the base of the skull. It produces hormones that control many different processes in the body, including metabolism, growth and reproduction. A nodule is a growth or lump in the body that could be benign (non-cancerous) or malignant (cancerous).
The pituitary gland is a small gland that sits in the sella turcica, a saddle-shaped depression located in the bone at the base of the skull. It produces hormones that control many different processes in the body, including metabolism, growth and reproduction. Pituitary adenomas are the most common benign growth of the pituitary that may appear as a nodule, and sometimes hormone production can be affected. Pituitary adenomas can occur at any age, but are most common in people in their 30s or 40s. When an adenoma is less than 1 cm, it is called a microadenoma.
This is a common anatomic variant (estimated 10-30% of people) where the carotid artery (instead of the basilar artery) supplies blood to the posterior cerebral artery of the brain. This is a congenital (present from birth) condition, and no further follow-up or evaluation is needed for this finding
Pituitary tumors are unusual growths that develop in the pituitary gland. This gland is an organ about the size of a pea. It's located behind the nose at the base of the brain. Some of these tumors cause the pituitary gland to make too much of certain hormones that control important body functions. Others can cause the pituitary gland to make too little of those hormones. Most pituitary tumors are benign.
Pneumonia is a viral and/or bacterial infection of the lungs. Symptoms include fever, dyspnea (shortness of breath), productive cough (coughing that brings up mucus), pleuritic pain (pain in the chest when inhaling and exhaling) and hemoptysis (blood in the mucus).
