Benign Lesions Flashcards
Orbital cavernous hemangioma- what is it?
A collection of small blood vessels surrounded by a fibrous pseudo capsule.
*Large vascular spaces are within the mass, thus the term cavernous.
Orbital cavernous hemangioma- etiology
Congenital venous malformation
Orbital cavernous hemangioma- demographics
Women > men
Dx between ages 30-50
Orbital cavernous hemangioma- unilateral or bilateral
Unilateral
Orbital cavernous hemangioma- symptoms
Bulging or displaced eye. Double vision
Orbital cavernous hemangioma- signs
Proptosis, globe displacement, restricted EOMs
Complications
Compression on the globe and/or ON
Thrombosis
Management
Orbital CT or MRI
If symptomatic or complications, refer out for complete surgical excision.
What is the most common benign orbital tumor in adits?
Orbital cavernous hemangioma
Most common location of Orbital cavernous hemangioma
Within muscle cone of the orbit
Growth of Orbital cavernous hemangioma may accelerate during
Pregnancy
Orbital Varices
Abnormally enlarged vein that becomes dilated with increased venous pressure- during valsalva maneuvers, bending forward, or holding breath.
Orbital Varices etiology
Thought to be congenital venous malformation
Orbital Varices demographics
10-20 years
Orbital Varices unilateral or bilateral
Unilateral
Orbital Varices symptoms
Intermittent bulging eye/displaed eye.
Intermittent double vision.
Signs of Orbital Varices
INTERMITTENT proptosis
INTERMITTENT globe displacement
INTERMITTENT restricted EOM
Pt complaining of double vision and proptosis that comes and goes
Orbital Varices complications
Compression on the globe or ON
Orbital hemorrhage - rapid and painful proptosis
Thrombosis
Orbital Varices management
Orbital CT or MRI
If complications, refer out for surgery
If pt has Orbital Varices, they might also have ___ varicies
Eyelid and conj
Lacrimal gland pleomorphic adenoma (benign mixed cell tumor)
What is it?
Benign tumor of the lacrimal gland due to proliferation of epithelial cells
Ages 30-40 years old.
Symptoms of Lacrimal gland pleomorphic adenoma (benign mixed cell tumor)
Displaced eye, double vision, eyelid swelling and redness.
Signs of Lacrimal gland pleomorphic adenoma (benign mixed cell tumor)
Globe displaced inferior and medially
Restricted EOM
Eyelid edema and redness
Palpable lacrimal gland mass
Lacrimal gland pleomorphic adenoma (benign mixed cell tumor) complications
Malignant transformation
Lacrimal gland pleomorphic adenoma (benign mixed cell tumor) management
Orbital CT or MRI
Refer out for complete surgical excision since it could become malignant
progression of Lacrimal gland pleomorphic adenoma (benign mixed cell tumor)
Slow, painless progression over the course of 12 months.
**rapid progression and pain may indicate malignancy.
