Question

The patient came with proptosis, restriction of eye movements, and was Euthyroid. What could this be from ?

• A. Orbital Cellulitis
• B. Orbital Lymphoma
• C. Orbital pseudotumor
• D. Thyroid ophthalmopathy

Answer 1

The Correct Option is C

The presented symptoms are indicative of an orbital condition. Let's evaluate each option:

• Orbital Cellulitis: This condition typically presents with proptosis and restricted eye movement due to infection. However, it is often accompanied by fever and systemic signs of infection, which are not mentioned here. The patient is euthyroid, meaning thyroid function is normal, which does not correlate with this diagnosis.
• Orbital Lymphoma: This can cause proptosis and eye movement restriction but typically grows slowly and might not cause acute symptoms. Also, euthyroid status does not exclude lymphoma but it makes it less likely given the symptom profile.
• Orbital pseudotumor: Also known as idiopathic orbital inflammation, this condition can cause proptosis and restricted eye movements. It is characterized by inflammation not associated with systemic disease or infections and often occurs with normal thyroid function. Being euthyroid fits well with this diagnosis.
• Thyroid ophthalmopathy: Also known as Graves' orbitopathy, it often presents with proptosis and eye movement restriction, related to thyroid dysfunction. However, the patient is euthyroid, which does not fit the common presentation of thyroid eye disease.

Considering the symptoms and the euthyroid status of the patient, Orbital pseudotumor is the most likely diagnosis.
