Not necessarily.  I agree that the term "message attachment" is
ill-defined in email, but the existence of an attachment does not
have to imply multipart.  An example is the use of Content-Disposition
which clearly allows one to specify a body part as an attachment.

Therefore, I could have the following:

  To: thomas(_at_)example(_dot_)com
  From: percy(_at_)example(_dot_)com
  Subject: Her is that image I told you about
  MIME-Version: 1.0
  Content-Type: image/jpeg
  Content-Transfer-Encoding: base64
  Content-Disposition: attachment; filename="image.jpg"

  ...

Basically, the main message body is an attachment.
