A 34 year old woman came with left ear discharge and left sided hearing loss since two months. On examination, past pointing and dysdiadokinesia were positive on the right side. The Romberg’s test was negative. Her gait was normal.
The plain CT scan of the skull shows an ill-defined lesion at the left jugular foramen and the adjacent petrous bone eroding causing irregular bone erosion. The MRI of the brain shows a heterogeneously T2 hyperintense lesion at the left petrous bone extending into the left jugular foramen. Cerebral angiography shows hypervascular tumoral blush supplied by hypertrophied tumoral feeders from the left occipital artery, ascending pharyngeal artery and middle meningeal artery.
The Romberg test is named after German neurologist Moritz Heinrich Romberg (1795-1873). He developed the test in the 19th century to help diagnose neurological issues related to late-stage syphilis, specifically tabes dorsalis
