Temporal Bone Plasmacytoma Presenting With a Mobile Third Window

xlomafota13 shared this article with you from Inoreader A Window Into the Whole Story: Temporal Bone Plasmacytoma Presenting With a Mobile Third Window Via The Laryngoscope A 63‐year‐old man presented with imbalance when coughing due to a respiratory tract infection. He had a history of multiple myeloma with a plasmacytoma of the left temporal bone. Examination revealed a positive leftward head impulse test, no spontaneous nystagmus, left‐beating positional nystagmus, and left‐beating Valsalva‐induced nystagmus. Videonystagmography, audiology, and comprehensive vestibular function tests revealed a subtotal left peripheral audio‐vestibular loss. Temporal bone computed tomography showed an unchanged bony erosion of the left labyrinth from 2 years prior. Vertigo subsided after treatment of the respiratory tract infection. Although no tumor progression was evident, coughing had triggered a preexisting third mobile window to declare itself. Laryngoscope, 131:E966–E969, 2021 View on the web Inoreader.
