KUSCH, Anne Marie  y  RUIZ GARCIA, Vilma. Giant pneumatization of sphenoid sinus: Report of four cases and review of literature. Rev Med Hered [online]. 2019, vol.30, n.1, pp.45-59. ISSN 1018-130X.  http://dx.doi.org/10.20453/rmh.v30i1.3472.

Sphenoid bone occupies most of the anterior part of the middle part of the skull base, it is compound by a body, two pair of wings (greater and lesser) which are laterally projected from the body and two pterygoid process projected inferiorly and laterally from choana. This bone represents the limit between the anterior and middle cranial fossa. Usually, the sphenoid sinus is located in the sphenoid body, and has a large variation in its pneumatization, ranging from absent to extensive. It is able to extent to different parts of the sphenoid bone or even to surrounding ones. The deep location makes difficult the radiographic diagnosis, especially when conventional radiographic techniques are used. Four cases of a giant pneumatization of the sphenoid sinus are presented observed as a radiological finding.
