Patient's question:
5 Eighteen years old, three days ago, I hit myself on the head with a small hammer. At the beginning, it was a very small bump, but now the bump has covered one-fourth of my head. The brain CT scan images show: no obvious abnormal density in the brain parenchyma, no obvious abnormalities in the sulci and cisterns, and the lateral ventricles have an unnatural shape. Bone window: no obvious signs of skull fracture. The posterior fontanelle gap is wider. There is swelling of the soft tissue on the right frontal top of the scalp. The maxillary sinus and sphenoid sinus show high density. Imaging diagnosis: 1. Brain CT scan shows no obvious abnormalities in the brain 2. Swelling of the soft tissue on the right frontal top of the scalp 3. High density of the maxillary sinus and sphenoid sinus. Past treatment and effectiveness: No treatment has been implemented. What kind of assistance is needed: What does "the shape of the lateral ventricles is unnatural" mean? What does "high density of the maxillary sinus and sphenoid sinus" mean? What should I do now that the bump is getting bigger and bigger?Doctor's answer:
Subcutaneous hematoma, which may be caused by a sudden blood vessel rupture, can occur in the ethmoid sinus and sphenoid sinus if there is broken skin or inflammation, or polyps.Advice: Since it has been 3 days, you can apply cold compresses to the swollen area daily to promote the absorption of the hematoma. Changes in the density of the ethmoid and sphenoid sinuses make it difficult to draw a conclusion. If there is broken skin, no special treatment is needed as it can resolve on its own. For inflammation, use anti-inflammatory medication. It is recommended to wait a few more days and recheck if there is no improvement or if it disappears, then no further action is necessary.
