After the clinical autopsy, she was diagnosed as a malignant form of multiple sclerosis – Marburg disease..

In A, axial T2 gradient eco Within the infarcts, there are hypointense areas sug- gesting the presence deoxyhemoglobin secondary to hemorrhages. Pathogenic variants within TFAP2A or deletion of the entire gene result in the branchiooculofacial (BOF) syndrome. MRI of the brain and orbits is notable for enhancement of the optic nerves on contrast-enhanced T1-weighted images and high signal in the optic nerves on T2-weighted images. Patients with paraneoplastic optic neuropathy typically present with subacute, painless visual loss. Usually, there is often otic capsule demineralization, but other mechanisms, such as labyrinthine compromise or narrowing in the internal auditory canal ( curved arrow) have been proposed as a cause of sensorineural hearing loss in these patients.
Contrast-enhanced axial T1-weighted MR image shows an enhancing mass occupying the IAC (arrow in B) and ex- tending out to the cerebellopontine angle( hipointense mass in axial T2, asterisk in A). The clinical course progressed to tetraparesis, resulting in the latest into bilateral sensorineural hearing loss clinical by affecting the cochlear nuclei in the pons. Grade of papilledemaMale patients, those with high-grade papilledema, and those with decreased visual acuity at baseline were more likely to experience treatment failure. Ophthalmic evaluation also shows the presence of vitreous cells, and retinal angiography demonstrates leakage from the optic disc vasculature. Although there is variability in presentation, a classic triad has been described consisting of optic disc edema, leakage from the optic disc vasculature on retinal angiography, and vitreous cells.
Small, linear or superficial branchial skin defects may heal spontaneously; however, some require surgical intervention. Anophthalmia or severe microphthalmia may require a conformer (a structure, usually plastic, inserted into the eye socket to encourage its growth); nasolacrimal duct stenosis or atresia often requires surgery. Neuroimaging may be normal or show patchy T2 signal changes and enhancement of the optic nerves.
Tekin et al [2009] reported a complex TFAP2A allele (deletion of 18 and insertion of 6 nucleotides) between amino acids 276 and 281 in an individual with BOFS.Table 2. The optic neuropathy is typically associated with multifocal neurologic deficits, including brainstem, spinal cord, or cerebellar dysfunction.
The visual acuity could not be determined reliably, nor could visual field testing be performed.
The majority of patients are seropositive for a serum antibody to a 62 kD neuronal antigen, collapsin response-mediator protein-5 (CRMP-5). The right fundus showed a tilted optic nerve with a swollen optic nerve rim (yellow arrow).
Each child of an individual with BOFS has a 50% chance of inheriting the pathogenic variant. Many of these patients harbor antibodies to the 62kDa collapsin-responsive mediator protein-5 (CRMP-5, also called anti-CV2) [42-44,46].
Prenatal diagnosis for pregnancies at increased risk is possible if the pathogenic variant has been identified in an affected family member.DiagnosisBackground. However, the small number of patients, the extensive number of accompanying symptoms, and the frequent co-occurrence of other antibodies suggest low specificity and sensitivity of CRMP-5 antibodies as markers of paraneoplastic optic neuritis or retinitis associated with SCLC [43].Patients typically present with painless visual loss and optic disc edema [13,43,47]. The branchiooculofacial syndrome (BOFS) is a distinctive craniofacial syndrome first characterized by Lee et al [1982], Hall et al [1983], and Fujimoto et al [1987]. It has a central basic DNA binding region, a carboxy terminus helix-span-helix motif that mediates dimerization, and an amino terminus that contains a transactivation domain [Eckert et al 2005]. There was no headache or other symptoms to suggest temporal arteritis, which would be unusual in any case in a patient of this age. Risk factors for poor visual outcome in patients with idiopathic intracranial hypertension. Nonarteritic ischemic optic neuropathy is thought to be caused by hypoperfusion of the optic nerve by the posterior ciliary arteries in patients with vascular risk factors.

Numerous gene interactions likely underlie the variability in phenotype resulting from molecular defects involving TFAP2A.
Wall M, Falardeau J, Fletcher WA, Granadier RJ, Lam BL, Longmuir RA, Patel AD, Bruce BB, He H, McDermott MP; NORDIC Idiopathic Intracranial Hypertension Study Group. There is a central retinal artery occlusion with pale optic nerve edema and very attenuated arteries.Pearls In the elderly the association of very severe visual loss with ocular ischemia and pallid optic nerve head edema acutely is essentially diagnostic. Details of the molecular findings are reported in Milunsky et al [2008] (patient 3, age 2 years).
Gestri et al [2009] studied the role of TFAP2A pathogenic variants in zebrafish eye morphogenesis that revealed an association with a multitude of ocular pathologies.
Neuropathologic findings demonstrate findings consistent with optic neuritis including perivascular lymphocytic infiltration and demyelination [43,47].In addition to encephalomyelitis and retinitis, other associated paraneoplastic syndromes occurring with PON include cerebellar ataxia [43,46,48-50], a Devic-like syndrome [43,44], and ophthalmoplegia [41,51]. In addition, the pathogenic variants compromised the gene function, thereby sensitizing the developing eye to deleterious mutation of other genes including bmp4 and tcf711a [Gestri et al 2009]. Damberg [2005] found that the AP-2 family may be involved in the regulation of the monoaminergic systems in the adult brain, resulting in neuropsychiatric disorders. Some patients are described with isolated PON [43,47,52-55].PON usually occurs in the setting of known cancer, but occasionally is its first manifestation [15].
Brewer et al [2004] noted that surviving mutated Tcfap2a mice have craniofacial anomalies, abnormal middle ear development, and defects in pigmentation.ReferencesLiterature CitedAhituv N, Erven A, Fuchs H, Guy K, Ashery-Padan R, Williams T, de Angelis MH, Avraham KB, Steel KP. Small cell lung cancer (SCLC) is the most commonly associated cancer, but PON along with anti CRMP-5 antibodies are described in non-small cell lung cancer [54,55], breast cancer [52], thymoma [44], renal cancer [43] and thyroid cancer [43].
