Occipital condyle syndrome (OCS) involves unilateral pain in the occipital region and ipsilateral hypoglossal nerve palsy and was first described almost 35 years ago during an analysis of 43 patients with skull base metastasis. In this report, we describe the clinical, radiological, and cytological characteristics of a non-smoker female patient with lung adenocarcinoma and OCS.
A previously healthy 60-year-old woman presented to us with right pleuritic chest pain and left occipital headache. She also complained of difficulty maneuvering food boluses in her mouth. A clinical examination revealed left hypoglossal nerve palsy [Figure 1]a; Supplementary Video 1]. Contrast-enhanced computed tomography scan of the thorax showed a 4 cm × 4 cm lobulated mass in of the right upper lobe [Figure 1]b with ipsilateral hilar and mediastinal adenopathy and pleural effusion. Magnetic resonance imaging (MRI) of the brain revealed altered signal intensity (T1 hypointense; T2 hyperintense) in a well-defined expansile intraosseous lesion involving the left occipital condyle [Figure 1]c. Pleural fluid cytology showed adenocarcinoma [Figure 1]d. A diagnosis of Stage IV non-small cell lung cancer (adenocarcinoma; T2aN2M1b) was made. No mutations in the epidermal growth factor receptor or rearrangement of the anaplastic lymphoma kinase gene were detected. The patient was started on pemetrexed–cisplatin chemotherapy and zoledronate, with simultaneous radiation to the skull base. After four cycles of chemotherapy, her tongue movements improved, MRI of the brain showed resolution of the lytic lesion, and there was a partial response as per the Response Evaluation Criteria in Solid Tumors (48.8% reduction in the size of the primary lesion was observed). The patient subsequently received another cycle of platinum doublet followed by maintenance pemetrexed. The timeline of events in the case is provided in [Table 1].

The hypoglossal nerve which innervates the tongue muscles exits the posterior cranial fossa just anterior to the occipital condyles. In disorders affecting the lower motor neurons of the hypoglossal nerve, the unopposed action of the contralateral genioglossus muscle causes the tongue to deviate to the affected side. Due to close proximity, lesions affecting the occipital condyle may also affect the hypoglossal nerve. OCS is a rare but stereotypic syndrome which is usually caused by metastatic disorders; however, chronic inflammatory states such as tuberculosis and granulomatosis with polyangitis have also been described as etiologies. Lung cancer is an unusual cause for OCS with four previously reported cases (including two cases of adenocarcinoma histology).,,,
This case report highlights the importance of scrupulous history taking and astute clinical examination and the incessant scuffle between Occam's razor and Hickam's dictum. In this particular case, we see the former taking an edge over the latter. Though we were not able to derive a tissue for cytological diagnosis from the expansile intraosseous lesion, the improvement in the weakness of tongue muscles, and resolution of the same on MRI following chemotherapy, indicates the metastatic nature of the lesion.
