Soft Spot On Top Of Head (Definition)

In an infant, the space where two skull-bone sutures join forms a membrane-covered "soft spot" called a fontanel (fontanelle). The fontanels allow for growth of the skull during an infant's first year. The fontanels should feel firm and very slightly curved inward to the touch. A tense or bulging fontanel occurs when fluid builds up in the skull cavity or when pressure increases in the brain (increased intracranial pressure). When the infant is crying, lying down, or vomiting, the fontanels may look like they are slightly bulging, but they should return to normal when the infant is in ...Read more

What is the definition or description of: Bulging fontanel?

Increased Pressure: A bulging fontanelle (soft spot on baby's head) is most likely due to increased intracranial pressure. This may be due to a number of factors, including head bleeds, an intracranial mass, or a defect in cerebral spinal fluid production/flow. It is a "safety valve" for babies, and it lets physicians know that a work-up needs to be performed quickly to determine the cause. ...Read more

My 6mnth LG'sp fontanelle is slightly bulging this morning. She is not feverish or fussy. She is eating & drinking as normal. Should I be concerned?

I wouldn't worry: Kudos that you're noticing these things. Don't get too obsessive. And no need to be pressing it really. Imagine if someone were messin' with your fonatanelle! Your baby is fine. If they change their behavior, develop a fever, a rash, diarrhea, strong odor to their urine, or reduce their feeding habits then, time to visit the pediatrician.

Hello iam 29 years man and i sm suffering from flu. I noticed little bulge in my lymph node in the neck of left side(under msndible) is it normal?

Lymph node: Yes, it is normal to have an enlarged lymph node under the mandible when you have the flu. The lymph nodes enlarge near the site(s) of infection while they are producing more white blood cells to fight the infection. In this case, enlargement is a healthy sign of a good immune response. It may take weeks for the lymph node swelling to resolve, so don't expect it to disappear immediately. ...Read more

What do you know about fontanel early closure?

What do you know about fontanel early closure?

Enough...: The anterior fontanelle usually closes between 7 and 21 months. Early closure (before 6 months) causes concern that perhaps other areas of the skull might be fusing too early and that leads to abnormal head growth (plagiocephaly). It can easily evaluated with a head x-ray. I have seen many cases and even with the fontanelle closed early the others are open. Surgery can fix if a problem is there. ...Read more

Is it normal for 1 year old and 2 month baby s fontanel to close because my nephew s fontanel is already closed and is it effect tooth formation?

That is normal: The frontal fontanel is typically completely closed by 18-24 months, but often feels hard/sealed by your fingers by around 1 yr, some a bit earler, some later. During routine infant exam, docs/nurses check this and so if baby has been growing, developing normally, without concern from his doc, I believe he is well/normal. Watch him do wonderful stuffs as he grows! Enjoy and good luck. ...Read more
