They kill them & the brain does not grow.Without brain mass the skull doesn't enlarge as fast =microcephaly. Many adults & older kids have few if any symptoms with zika.

Yes.: Adults can develop extracranial germ cell tumors. These can be either benign or malignant. Behavior of these tumors depends upon the location / the organ (site) in which the tumor develops and upon the microscopic and molecular-genetic features of the individual tumor.

Viral exposure +: fThe epidermoid tumors have been around or a long time in association with viral exposure to HPV. Sloan Kettering began as a hospital for treating advanced cervix Ca. It also occurs in the oral cavity from smoking and alcohol abuse as one can see in the lung from excessive smoking. Antivirals and reduction in smoking can diminish incidence of this disease. ...Read more
Unlikely: There is a definite association between herpes simplex type 2 and recurrent (mollaret's) meningitis, but encephalitis would be very unusual in an immune competent host. On the other hand, genital herpes can be due to type 1, and that can certainly, but uncommonly, produce meningitis, encephalitis or meningoencephalitis unpredictably. ...Read moreSee 2 more doctor answers
No: Benign lung nodules are not rare and are found during routine chest x-rays or, more likely ct scans. The most common are hamartomas or adenomas that are totally innocent if they are in the outer lung as usual but can block a lung if they are in one of the bronchial tubes. Although, pet scans can help determine that these are benign, some require surgical removal to assure that they are benign. ...Read more
Why is pituitary adenoma infratentorial in adult tumors but craniopharyngioma is supratentorial in childhood?
Sella Turcica: The tentorium cerebelli separates the cerebellum from the cerebrum. Supratentorial means ABOVE the tentorium and Infratentorial means BELOW. The pituitary gland sits in a special area called the hypophyseal fossa or sella turcia which is technically neither. Craniopharyngioma and pituitary adenoma grow SUPRATENTORIALLY in almost all cases, but rarely invade the clivus into the posterior fossa. ...Read more

Yes: When saying "catch", you would need to be more specific. As far as being a carrier, yes, they can, unless they had as a child. As far as having symptoms of it, much less likely, as it is common in children and adults have probably had it even if it was not diagnosed as such. ...Read moreSee 1 more doctor answer
Comparison to fordyce spots/warts/herpes: fordyce spots occur in larger numbers (50-100's) whereas herpes/warts are fewer in number? Is this correct?
Partly: It varies. Fordyce spots are visible sebaceous(sweat)glands that are a normal variant. They appear as rice sized tiny papules raised above the surface of the skin. Typically they are very numerous on the scrotum and vulva and less so on the penile shaft. When few in number they can be confused with HPV or warts. You can see pictures of all 3 conditions by going to Google Images. ...Read moreSee 2 more doctor answers
Bilateral lung nodules,Atelectasis prior papilloma thyroid CA.Pituitary Adenoma,Chiari Malformation,FMD,enlarged common bile duct no stones. Genetic?
Maybe genetic: Probably should have genetic consult. Forinstance Chiari malformation, fibromuscular dysplasia, and thyroid cancer can be associated with neurofibromatosis. Lung nodules are non specific and can be from some infections but also metastatic disease sometimes from papillary thyroid cancer. You may want to consult a geneticist physician. ...Read more
Have hashimoto's; demyelinating brain lesions, one atypical; benign vertebral lesions, one atypical hemangioma. R these connected, or possible MS too?
Not connected: Hemangiomas and multiple sclerosis lesions can be difficult to differentiate on mri.
