Which of the following tumors is not commonly known to increase size during in pregnancy ?: (A) Glioma, (B) Pituitary adenoma, (C) Meningioma, (D) Neurofibroma
Answer is A. Let us have a look at each option one by one
Pituitary adenoma (option b): Enlargement of both microadenomas and macroadenomas (> 10 mm) is seen during pregnancy, less in case of microadenoma and more in case of macroadenoma.
Williams 23/e, p 1140
“Neurofibromas and meningiomas although brain tumors are not specifically related to gestation, meningiomas, angiomas and neurofibromas are thought to grow more rapidly with pregnancy.”
COGDT 10/e, p 398
“Lesions of neurofibromatosis may increase in size and in number as a result of pregnancy.”
Williams 23/e, p 1191
I did not get any text specifically mentioning the relationship between glioma and pregnancy but by exclusion the answer is Glioma.
