A Case of Cerebellar Metastasis Mimicking Vestibular Neuritis: Yeong Joon Kim, Chang Hoi Kim, Hwan Ho Lee; Res Vestib Sci. 2015;14(4):143-146.

Abstract PDF: Vestibular neuritis is characterized by rapid onset of vertigo, nausea and vomiting without neurological symptoms or signs, but central vestibular lesions can cause similar symptoms and signs. A 66-year-old woman previously diagnosed with ovarian cancer initially presented with vertigo. The patient had typical symptoms and signs of vestibular neuritis. As time proceeded, the patient presented with bilateral catch-up saccade and the symptoms and signs of cerebellar dysfunction. Magnetic resonance image and computed tomography scan showed brain metastasis surrounded by edematous lesion. We report an ovarian cancer patient with metastasis mimicking vestibular neuritis with a review of related literature.

Cerebellopontine Metastatic Carcinoma of Small Cell Lung Cancer Mimiking Vestibular Neuritis: Young Hyo Kim, Kyu Sung Kim, Yoon Seok Oh, Hoseok Choi; J Korean Bal Soc. 2007;6(2):226-229.

Abstract PDF: A 77-year-old man visited our department because of dizziness from one month ago. Dizziness was continuous and non-whirling and this type of dizziness was the first time. He also complained of tinnitus and hearing impairment of the right ear. On physical examination, he showed spontaneous left-beating horizontal and torsional nystagmus and rightward head thrust was positive. He was admitted under the first impression of right vestibular neuritis. On inner ear MRI, there was a well-demarcated 2.5×2.3 cm sized mass of right cerebellopontine angle. This mass showed somewhat low signal intensity in both T1 and T2-weighted image and modest enhancement with Gadolinum. And approximately 4.5×3 cm sized mass could be seen in the simple chest roentgenogram. On chest CT, there was a poorly demarcated 3×2.5 cm sized mass in left lower lobe of lung. The patient was diagnosed as small cell lung cancer with brain metastasis by Per-Cutaneous Needle Aspiration of lung. In spite of radiotherapy and concurrent chemotherapy, he expired after 5 months.

A Case of Isolated Unilateral Abducens Nerve Palsy Caused by Clival Metastasis from Rectal Cancer: Won Hee Chung, Jeong Ho Park, Sun Ah Park, Ki Bum Sung; J Korean Bal Soc. 2006;5(1):78-80.

Abstract PDF: A wide variety of abnormalities, both primary to the nerve itself and secondarily involving the nerve, can cause isolated abducens nerve palsy. Skull base lesions are also regarded as possible causes of isolated abducens nerve palsy but clival metastasis from systemic malignancy has rarely been reported. We report a case of isolated abducens nerve palsy caused by clival metastasis from rectal cancer. Key Words : Abducens nerve palsy, Metastasis, Skull base, Rectal neoplasm
