The pattern of lytic or punched-out radiolucent lesions on the skull have been described as resembling raindrops hitting a surface and splashing.
Are lytic lesions always cancer?
They are benign, asymptomatic tumors with a well-defined sclerotic margin. They are usually juxtacortical in location and typically occur in the metaphysis of long bones, and are most common in the under 30 age group.
Are skull lesions common?

What is the difference between a tumor and a lesion?
A lesion describes any area of damaged tissue. All tumors are lesions, but not all lesions are tumors. Other brain lesions can be caused by stroke, injury, encephalitis and arteriovenous malformation.
What is osteoblastic lesion?
Sometimes, the cancer cells release substances that turn on the osteoblasts. This leads to new bone being made without breaking down the old bone broken down first. This makes areas of the bones harder, a condition called sclerosis. The areas of bone where this occurs are called osteoblastic or blastic lesions.
What does myeloma do to your head?
In some patients, large amounts of myeloma protein can cause the blood to “thicken.” This thickening is called hyperviscosity. It can slow blood flow to the brain and cause: Confusion. Dizziness.

What does a tumor on the skull feel like?
These tumors can grow slowly or rapidly. Symptoms of chondrosarcomas depend on their location in the skull base and may include headache, ringing in the ears, and problems with vision, hearing, or balance.

Differential diagnosis is broad which includes both benign and malignant lesions. Majority of these are benign.
What are osteoblastic metastases of breast cancer?
But, when you see multiple lesions, you should consider the diagnosis of osteoblastic metastases. This is the typical appearance of metastatic bone disease from prostate cancer, but in women, treated breast cancer metastases can also have this appearance. Figure 1.
What is a benign cystic lesion of the skull?
Benign cystic lesion of the skull CONCLUSION Osteolytic skull lesions may be the presentation of many pathologies which may vary from infective, benign and malignant tumors. Proper clinical evaluation of the patient must be done including systemic examination for optimum treatment.
What are the abnormalities of fibrous dysplasia of the skull?
The abnormalities are of higher attenuation than the skull. One case features a right-sided skull fracture and a well-marginated lesion with homogeneous dense bone that appears expanded. This appearance of bone is called ground-glass, and it is typical for a benign process in the bone called fibrous dysplasia.
