Further, fine-needle aspiration appears to be safe for suspected hydatid disease. The presence of acellular laminated membranes confirms the diagnosis.\r\n \r\nHowever, FNA should not be used routinely, as imaging and serological tests are noninvasive and usually sufficient to establish the diagnosis.\n"}]}
