Orbital Intradiploic Giant Epidermoid Cyst

Abstract

e report a case of an intradiploic epidermoid cyst of the lateral orbital wall that resulted in proptosis and downward displacement of the left eye. Computed tomography and magnetic resonance imaging revealed a bone-destroying mass involving the frontal, sphenoid, and zygomatic bones that extended into the orbit, temporalis, and anterior cranial fossa. Complete surgical removal was performed through a lateral orbitotomy. The lateral wall was reconstructed with a porous polyethylene sheet. The cyst has not recurred after 18 months of follow-up.

Diagnosis of an epidermoid retroperitoneal cyst via ultrasound: A case report

“…Surgery is the primary treatment approach for epidermoid RPCs 20,21 . These cystic lesions, despite their benign nature, can present technical challenges during excision due to their proximity to major vessels or adjacent organs 22 . In our case, the lesion was situated adjacent to the caudal vertebra, necessitating careful preparation and presenting a technical challenge during the procedure.…”

Spheno-orbital Lesions—A Major Review of Nonmeningioma Causes

“…The list of our own and published lesions appears in Table 2. 2–99 Published cases of 4 of the listed diagnoses were not reviewed because there is a significant literature on these already (sickle cell crisis with sphenoid infarction, tuberculosis of orbital bone, sphenoid bone dysplasia in NF1, and fibrous dysplasia of bone). During the same period as these new cases were collected from our practices, 97 cases (21 males) of spheno-orbital meningioma were encountered by us.…”

“…Epidermoid cysts may arise within the diploe of the greater wing of the sphenoid bone. [2][3][4][5][6][7][8][9] They generally present in mid to late adulthood with slowly progressive symptoms of mass effect, and rarely infection 4 or hemorrhage. 6 They are usually large lesions that expand the GWS, with smooth corticated bone, which may be thickened or eroded in the orbit, temporal fossa, or middle cranial fossa.…”

Endoscope-Assisted Removal of Post-Traumatic Orbital Epidermoid Inclusion Cyst: A Useful Adjunct

“…Orbital lesions should be approached based on their location within the orbit. Open methods such as orbitotomy and craniotomy have been advocated ( 5 , 6 ). However, a combined open and endoscopic approach provided superior visualization in our case.…”
