Question

Which one of the following is NOT associated with Cephalhematoma?

• A. Swelling is present at birth
• B. Usually involves parietal and occipital bone
• C. Bleeding is subperiosteal
• D. Usually reabsorbed in 2-3 months

Hint:

Remember that a cephalhematoma is blocked by the suture line and stays within one bone.

Answer 1

The Correct Option is B

Step 1: Understanding the Question.
We need the statement that does NOT match how a cephalhematoma usually behaves.

Step 2: Key Concept.
A cephalhematoma is bleeding that collects under the periosteum covering a skull bone, caused by torn vessels during a difficult delivery. Because the periosteum is firmly attached at each suture line, the swelling always stays limited to a single bone and never crosses a suture, unlike caput succedaneum which can spread across sutures.

Step 3: Detailed Explanation.
Option (A), swelling present at birth, is a true feature seen in these babies and fits the general description of the lump being noticed once the head is examined.
Option (B), usually involves parietal and occipital bone together, does not match the usual pattern. A cephalhematoma is almost always confined to one single bone, most commonly just one parietal bone, and it does not typically spread across two separate bones like the parietal and occipital together, since the periosteal attachment at the suture line blocks that spread.
Option (C), bleeding is subperiosteal, is the defining feature of a cephalhematoma.
Option (D), usually reabsorbed in 2 to 3 months, matches the standard natural course of a cephalhematoma, which slowly resolves as the blood is reabsorbed.

Step 4: Final Answer.
Since a cephalhematoma is normally confined within one single bone and does not usually involve two bones together, statement (B) is the one that is not associated with it. \[ \boxed{\text{Usually involves parietal and occipital bone}} \]
