“…In our case, the patient presented with paralysis of the palate and anesthesia of the pharynx along with Horner's syndrome, which makes Villaret syndrome and Tapia syndrome different. [5][6][7][8] The hypoglossal and glossopharyngeal nerves pass through the space between the transverse process of the atlas and the styloid process, which is populated by tumor cells, as seen on MRI. Involvement of the occipital condyle, jugular foramen, and hypoglossal foramen by inflammatory exudates, tumors, and local tissue trauma can lead to similar presentations.…”

Jugular foramen syndrome is an uncommon condition with a wide range of possible causes. We present a rare case of Villaret syndrome as an example of jugular foramen syndrome and illustrate a clinical-radiological approach for diagnosing jugular foramen syndrome. The morphological similarities between mesenchymal tumors such as rhabdomyosarcoma and phyllodes seen in our patient make immuno-histochemical (IHC) characterization essential for a definitive diagnosis. Jugular foramen syndromes, including Vernet syndrome, Collet Sicard, Villaret, Tapia, Jackson, and Schmidt, can manifest with multiple cranial nerve deficits in contiguous areas. In our case, the patient exhibited palate paralysis, pharyngeal anesthesia, and Horner's syndrome, thereby highlighting the differential diagnoses of Villaret syndrome and Tapia syndrome.

“…Recently, a contrast-enhanced 3D-T1-turbo spin-echo (TSE) black-blood sequence has gained attention, showing optimal diagnostic performance in depicting cranial nerve enhancement as it suppresses signals from vessels, including the near venous plexuses, and provides an increased contrast-to-noise ratio [ 9 , 10 ].…”

Cranial nerve enhancement is a common and challenging MRI finding that requires a meticulous and systematic evaluation to identify the correct diagnosis. Literature mainly describes the various pathologies with the associated clinic-radiological characteristics, while the radiologist often needs a reverse approach that starts from the radiological findings to reach the diagnosis. Therefore, our aim is to provide a new and practical pattern-based approach to cranial nerve enhancement, which starts from the radiological findings and follows pattern-driven pipelines to navigate through multiple differential diagnoses, guiding the radiologist to reach the proper diagnosis. Firstly, we reviewed the literature and identified four patterns to categorize the main pathologies presenting with cranial nerve enhancement: unilateral linear pattern, bilateral linear pattern, unilateral thickened pattern, and bilateral thickened pattern. For each pattern, we describe the underlying pathogenic origin, and the main radiological features are displayed through high-quality MRI images and illustrative panels. A suggested MRI protocol for studying cranial nerve enhancement is also provided. In conclusion, our approach for cranial nerve enhancement aims to be an easy tool immediately applicable to clinical practice for converting challenging findings into specific pathological patterns.

“…In general, high-contrast signal-to-noise ratio of 2D spin-echo sequences allows optimal evaluation of fat planes, whereas 3D-T1 gradient sequences are useful for their high spatial resolution and relative speed. Compared to gradient-based sequences, 3D turbo spin-echo sequences, both T1 and T2 weighted, offer intrinsically lower susceptibility artifact and has demonstrated promise in skull base and cranial nerve imaging, both intracranially and extracranially [ 18 – 20 ]. Some authors also advocate for use of balanced SSFP sequences with and without gadolinium to evaluate the extraforaminal cranial nerves, as the enhancement of surrounding structures, such as venous plexuses or pathology, better distinguishes them from the intrinsically hypointense, non-enhancing cranial nerve [ 13 ].…”

CT and MRI findings of tongue ptosis and atrophy should alert radiologists to potential pathology along the course of the hypoglossal nerve (cranial nerve XII), a purely motor cranial nerve which supplies the intrinsic and extrinsic muscles of the tongue. While relatively specific for hypoglossal nerve pathology, these findings do not accurately localize the site or cause of denervation. A detailed understanding of the anatomic extent of the nerve, which crosses multiple anatomic spaces, is essential to identify possible underlying pathology, which ranges from benign postoperative changes to life-threatening medical emergencies. This review will describe key imaging findings of tongue denervation, segmental anatomy of the hypoglossal nerve, imaging optimization, and comprehensive imaging examples of diverse pathology which may affect the hypoglossal nerve. Armed with this knowledge, radiologists will increase their sensitivity for detection of pathology and provide clinically relevant differential diagnoses when faced with findings of tongue ptosis and denervation.
