Classic stigmata of congenital syphilis SNHL, interstitial keratitis, Hutchinson teeth (notched incisors), mulberry molars, Clutton joints (bilateral painless knee effusions), nasal septal perforation & saddle deformity& frontal bossing. We report on a patient with brain metastasis involving bilateral internal auditory canal from non-small cell lung cancer (NSCLC). A 49-year-old female patient came to our outpatient department with a 3-month history of continuous vertigo. Pure tone audiometry shows sensorineural hearing loss on both sides (A), and bithermal caloric test shows canal paresis of 75% on the right side (B). Magnetic resonance imaging of the brain shows irregular nodular enhancement within both internal auditory canals with leptomeningeal enhancement (arrows) (A); multiple tiny rim enhancing parenchymal metastases (arrows) (B). Magnetic resonance imaging of the brain shows partial reduction of a metastatic mass in the bilateral internal auditory canals (arrows). The vast majority of lesions of the cerebellopontine angle (CPA) and IAC are benign tumors such as vestibular schwannoma and meningioma [7].
Facial nerve palsy was reported as the most common symptom of bilateral IAC metastasis, and facial paralysis on at least one side was observed in all patients with bilateral IAC lesions [8]. In our patient, the suspicion of IAC metastasis was not difficult because lung adenocarcinoma is one of the most common primary sources of brain metastasis, and the patient did not receive any treatment for three months since the diagnosis of the disease.
Thorough history taking and physical examination are crucial in diagnosis of metastatic tumor of IAC, and a high index of suspicion would enhance the correct diagnosis since distinctive radiological features of IAC metastasis may not be observed on MRI.
Discussion: Large vestibular aqueduct syndrome is thought to be the most common identifiable cause of congenital hearing loss.

A 49-year-old woman who had been diagnosed with NSCLC (T2aN1M0) complained of persistent vertigo and bilateral tinnitus for three months.
Pulmonary adenocarcinoma, which constitutes approximately 35% of lung cancer, has been reported to cause brain metastasis in up to 28% of cases [2,3]. However, differential diagnosis between IAC metastasis and primary benign tumors such as vestibular schwannoma is often difficult. Attention should be paid when patients who have or had primary malignancy with high incidence of brain metastasis show symptoms such as vertigo, hearing loss, tinnitus, and facial nerve palsy with rapid progression or sudden onset. The patient had refused all treatments, including surgery and chemotherapy; however, she sought alternative medicine.
Metastasis to the temporal bone from the pulmonary adenocarcinoma is not uncommon, and solitary metastasis to the internal auditory canal (IAC) has been reported [4,5].

The patient exhibited left-beating spontaneous nystagmus, and head impulse test showed a catch-up saccade on the right side. The most common origins of metastasis to the temporal bone are breast cancer, lung cancer, renal cancer, stomach cancer, and prostate cancer [8]. Persistent vertigo and bilateral tinnitus were the chief complaint of our patient, whereas facial paralysis was not observed.
Clinical history of rapidly progressing sensorineural hearing loss accompanied by severe facial paralysis might raise the possibility of IAC metastasis, even though 30% of patients with unilateral IAC metastasis can be asymptomatic [8,10]. However, EGFRtyrosine kinase inhibitor (TKI) would be a favorable treatment option in patients who harbor activating EGFR mutation regardless of leptomeningeal carcinomatosis [12,13].

Development of central nervous system metastases in patients with advanced non-small cell lung cancer and somatic EGFR mutations treated with gefitinib or erlotinib. The patienta€™s hearing loss showed rapid progression bilaterally, and rotatory vertigo with peripheral-type nystagmus developed. Hematogenous dissemination, leptomeningeal carcinomatosis, and direct extension from the adjacent areas are considered as possible routes to temporal bone metastasis, and hematogenous spread accounts for most cases of brain metastasis.
While bilateral sensorineural hearing loss was revealed on PTA, caloric response showed canal paresis on the right side, even though the size of metastatic nodules was comparable bilaterally. It has been reported that a lack of distinctive features on brain MRI in IAC metastasis makes differentiation from benign tumors more difficult [10]. Our patient showed a similar response to EGFR-TKI; she showed a partial response after first-line gefitinib, with progression-free survival of five months.
Magnetic resonance imaging of the brain showed irregular nodular enhancement within both internal auditory canals with leptomeningeal enhancement and multiple intracranial metastasis. We report on a patient with multiple intracranial metastases involving bilateral IAC from pulmonary adenocarcinoma.

Except for headache, no other neurologic symptoms, including facial nerve paralysis, were observed. Bilateral IAC involvement was reported to occur in almost half of patients with IAC metastasis [8].
It was reported that facial paralysis may not be observed even though the facial nerve was infiltrated with metastatic cancer cells in IAC [9]. In general, vestibular schwannoma shows a homogeneous and isointense signal compared to gray matter on both T1- and T2-weighted images, and exhibits strong postgadolinium enhancement. While the tumor progressed after one cycle of second-line pemetrexed, reduction in tumor volume was observed after the patient received third-line erlotinib. The patient was treated with epidermal growth factor receptor-tyrosine kinase inhibitor, and the tumor showed partial response. The route of metastasis into IAC is still unclear, but spread of metastatic lesions into meninges and CSF is generally considered the mechanism of tumor deposits in IAC. The presence of thick linear and extranodular contrast enhancement on MRI may favor metastasis [11].
This was a rare case of multiple brain metastases involving bilateral internal auditory canal from known NSCLC presenting with vertigo and hearing loss. Even distribution of malignant cells bilaterally in the CSF can lead to bilateral IAC involvement [8].
MRI findings of irregular nodular enhancement within the IAC with leptomeningeal enhancement, as shown in the current patient, may be helpful in the differential diagnosis. The patient had been diagnosed four months ago with non-small cell lung cancer (NSCLC, T2aN1M0) at another hospital (Fig.
Magnetic resonance imaging (MRI) of the brain showed irregular nodular enhancement within both IAC with leptomeningeal enhancement and multiple tiny rim enhancing parenchymal metastases (Fig.
Subsequently, she received gefitinib as palliative treatment for primary and metastatic tumor and palliative whole brain radiation therapy to a total dose of 30 Gy in 10 fractions.
However, the patienta€™s hearing showed progressive deterioration despite chemotherapy, and PTA showed total deafness on both sides. The patient complained of aggravation of oscillopsia, and head impulse test showed bilateral catch-up saccade, indicating bilateral vestibulopathy.
