Meningiomas are common intracranial neoplasms. Meningomas are rarely subjected to fine-needle aspiration (FNA) studies. However, intraoperative squash preparations are commonly done. FNA of meningiomas are usually performed incidentally for cases with a clinical suspicion of some other disease such as metastatic carcinoma. We are reporting two cases, which were referred to our center with a diagnosis of metastatic carcinoma on FNA from swelling of the temporal region. We are discussing the characteristic cytomorphological features, which help in diagnosing meningiomas, the common cytological differentials, and the utility of immunohistochemistry (IHC) on cell block preparations in confirming the diagnosis, especially when there is a clinical differential diagnosis.
