Introduction
• Neurological involvement is a frequent
occurrence in SLE.
• Associated with increase in morbidity and
mortality.
• About 50% of SLE patients have
neuropsychiatric phenomena at some time
during their illness.
Introduction
• NPSLE extremely difficult to diagnose wide variety of neuropsychiatric symptoms
of the disease
• Neuro-imaging has become important in
the evaluation of SLE patients with
neurologic symptoms.
AIMS & OBJECTIVES:
To describe the MR imaging pattern in children
and young adults with neuro psychiatric
involvement in systemic lupus erythematosus
(NPSLE).
Materials and methods
• Design:
– Retrospective case analysis.
• Methodology:
– Patients of systemic lupus erythematosus who
presented with neuro-psychiatric symptoms.
– Detailed history & clinical examination done in
all patients.
– All patients fulfilled the criteria of 1999
consensus document of ACR that defines the
neurologic and psychiatric manifestations of
SLE.
Materials and methods
• MRI brain performed on 1.5 Tesla system.
• Axial Tl-weighted images (TR: 570 ms; TE: 14 ms;
four excitations),
• Axial proton density and T2-weighted images
(TR 2735/2500 ms; TE 102 ms; two excitations).
• Coronal FLAIR sequences (TR: 8000ms TE :110ms)
• Diffusion imaging (TR 5700 ms TE139ms)
• MR scans were read by two neuroradiologists
who were blinded for the clinical information.

Total patients = 14.
Mean age = 15.21 years (Range: 7-25 years).
Male: female = 5:9.
Mean duration of onset of illness: 2.4 yrs.

Discussion
• Incidence : 14% to 75 %
• Manifestations can range from mild to severe
• NPSLE events occur at the disease onset or
within 1-2 years after SLE diagnosis
Primary NPSLE
directly attributed to active disease
< 40 %
Secondary NPSLE
cause unrelated to SLE

Discussion

• White mater damage
• Infection
Summary
• Findings in young and children similar to
adults.
• Supratentorial involvement more common.
• Average time of onset of NPSLE 2 yrs.
• Atypical findings must be kept in mind to
avoid misinterpretation.
