Clinical data of patients with scleritis analyzed by CT and/or MR imaging

Pt	Duration of Symptoms^{^a}	US Performed, Diagnosis	Clinical Diagnosis^{^b}	Imaging Modality	Systemic Disease	Final Diagnosis
1	5 mo	No	Infectious cellulitis	CT	Down syndrome	IOID with scleritis
1	2 mo	No	Infectious cellulitis	CT	Down syndrome	IOID with scleritis
2	3 mo	Yes, disc edema	Optic neuritis	MRI	Not found	Bilateral idiopathic scleritis
3	2 mo	No	Intraorbital mass	CT	Not found	Idiopathic scleritis
4	2 mo	Yes, uveal mass	Choroidal melanoma	CT	Not found	Nodular idiopathic scleritis
5	Acute	No	Infectious cellulitis	CT, MRI	DRM; Colon carcinoma	Infectious orbital disease with panophthalmitis
6	6 mo	No	Infectious cellulitis	CT, MRI	Down syndrome	IOID with sclerouveitis
7	1 mo	Yes, scleritis	Scleritis or tumor	MRI	Granulomatosis with polyangiitis	Autoimmune orbital inflammation with scleritis
8	2 mo	No	Uveitis	CT, MRI	JIA	Autoimmune sclerouveitis
9	3 wk	Yes, inconclusive	Optic pathway condition	CT, MRI	None	Idiopathic scleritis
10	4 wk	No	Optic pathway condition	MRI	None	Idiopathic scleritis

Note:—DRM indicates dermatomyositis; JIA, juvenile idiopathic arthritis; Pt, patient; US, ultrasonography.
↵a Duration of symptoms refers to the time elapsed between onset of symptoms of scleritis (pain, vision disturbances) and the time of imaging.
↵b Diagnosis after ophthalmologic evaluation and ultrasound and before CT and/or MRI.
