Download - Tumefactive Demyelination
• Tumefactive demyelinating lesions (TDL) is an acute, inflammatory presentation of large acute demyelinating lesions (>2 cm) that can be associated with mass effect17.
• TDLs are rare but can mimic brain neoplasms or abscess because of their associated edema within the cerebral hemisphere18.
• TDLs are also known as tumefactive multiple sclerosis lesions, tumor-like demyelinating lesions, demyelinating pseudotumor18.
• They primarily affect females, ages 2 through 70 with the average age being 37.
• Tumefactive demyelination is a rare neurological disorder that can present with multiple symptoms: cognitive, sensory, motor, visual and cerebellar.
• Patients with visual symptoms may initially present with sub- acute or acute vision loss but may not have any associated neurological symptoms at the time.
• This case will discuss the clinical quandaries of suspecting demyelinating changes.
BackgroundVision loss, visual field loss, decreased color vision
and pallor of optic nerves warrants an urgent
work-up, both ophthalmic as well as systemic.
• DDX: optic neuritis/ optic neuropathy
• ischemic, inflammatory, infectious, compressive,
neoplastic or hereditary etiology.
• Inflammatory demyelinating disease spectrum
• Multiple sclerosis (MS), neuromyelitis optica
spectrum disorder (NMOSD), acute
disseminated encephalomyelitis (ADEM)
• Within the MS category - tumefactive
demyelinating lesions
• Tumefactive lesions may be the initial
presentation of relapsing MS seen in about 50-
70%7.
• TDLs occupy more space and can cause seizures,
hemiparesis, neglect or encephalopathy7.
In this case of tumefactive demyelination, time may be a factor in getting the best visual outcome. MS can appear with ocular related symptoms early on. • Clinical presentations can vary from mild
symptoms to severe.• Presentation can vary from typical MS cases.• In some cases, asymptomatic patients remained
untreated and were shown to improve on their own.
• Our patient reported her symptoms worsening over 2–3-month period, justifying treatment.
Treatment: IV Solumedrol + Plasma Exchange (PLEX)• It is imperative to have a clear history of
patient’s presenting symptoms and associated review of systems.

VARICELLA ZOSTER VIRUS ASSOCIATED WITH PRESEPTAL CELLULITISSamantha Wang O.D. and Zanna Kruoch O.D., F.A.A.O.
Malcom Randall VA Medical Center, Gainesville, FL
ABSTRACTThis is a case report of a patient with varicella-zoster infection with a
secondary bilateral preseptal cellulitis. This report highlights secondary
bacterial infections as one of the possible complications of a varicella
infection.
CASE HISTORYDemographics: 67-year-old Asian male
Chief Complaint
Periorbital pain and eyelid swelling OU that began 5 days prior.
Symptoms constant and severe
Ocular History: Unremarkable
Medical History: Unremarkable
Medications: Oral valacyclovir 1000 mg BID prescribed by primary
care provider 3 days prior
EXAM FINDINGSGross Examination: Crusted necrotic vesicular scab-like lesions
localized to the right forehead and right upper eyelid.
Adnexa: Bilateral periorbital edema and erythema OD>OS (Figure 1)
Figure 1
EOMs, CVFs, Pupils: Could not be assessed due to the severe eyelid
swelling and pain
BCVAs: Unable to be recorded OD, 20/50 OS
No ocular involvement OU to the extent seen
DISCUSSIONVaricella-Zoster Virus (VZV)
About
• A human herpes virus that causes varicella (chickenpox) as a
primary infection followed by latency in peripheral ganglion.1
• The latent VZV may reactive to cause herpes zoster (shingles).1,2
Classic Sign
• Right or left-sided vesicular rash that follows a characteristic
dermatomal distribution.
Ocular Complications
• Postherpetic neuralgia, stromal keratitis, giant cell arteritis,
vasculopathy, and secondary bacteria infections especially in
immunocompromised individuals.1,2,3
Treatment and Prevention
• Oral antivirals and vaccinations
Preseptal CellulitisAbout
• Infection located anterior to the orbital septum involving
periorbital region.4
• Most commonly caused by trauma, insect bites or spread of a
systemic infection.5
• Most common organisms isolated are the Staphylococcus and
Streptococcus species. Very rarely, associated with VZV
(secondary bacterial infection). 4,5,6
Demographics and Prognosis
• More common in childhood and with good prognosis. However,
if left untreated can cause severe complications including
orbital cellulitis, orbital abscess, and cavernous sinus
thrombosis.7
Signs
• Periorbital erythema, edema, and eyelid swelling. Vision and
pupils are usually normal. Typically, no proptosis or
ophthalmoplegia that is seen in orbital cellulitis.7,8
Treatment
• Oral antibiotics in mild infections, hospitalization and
intravenous antibiotics in severe cases.
CONCLUSION AND CLINICAL PEARLS
1. A VZV infection can lead to many complications and secondary
infections.
2. Prompt recognition and initiation of treatment can prevent the
spread of infection and potentially be life-saving.
DIFFERENTIAL DIAGNOSESVZV associated with orbital cellulitis, VZV associated with
preseptal cellulitis, Severe post-herpetic neuralgia from
VZV
INITIAL ASSESSMENTVZV associated with Bilateral Orbital Cellulitis.
TreatmentImmediate hospitalization referral for IV antibiotics. Return for follow-
up two weeks later.
Hospital Notes“A CT scan of his face had shown moderate soft tissue edema
overlying the right lateral orbital region without any focal fluid
collection. There was no sign of fluid crossing the sinuses or orbital
septum”
Patient was diagnosed with preseptal cellulitis, received IV
vancomycin and cefepime for 3 days, and then discharged with oral
clindamycin to take for 7 days.
Two-Week Follow-UpSignificant improvement in both signs and symptoms. Patient still had
vesicular scab-like lesions localized to the right forehead and right
upper eyelid; however, the bilateral eyelid swelling completely
resolved (Figure 2). Rest of the exam was unremarkable.
