Abstract
ABSTRACT Cavernous sinus metastasis from head and neck cancers is rare. We report FDG PET/MRI findings of cavernous sinus metastases from laryngeal cancer in a 56-year-old woman. The images revealed isointense lesions in the bilateral cavernous sinus on T2-weighted MR, with slight enhancement, and intense FDG uptake. The lesions were confirmed as metastases to the cavernous sinus.

Abstract
Cerebrovascular complications from blunt trauma to the skull base, though rare, can lead to potentially devastating outcomes, emphasizing the importance of timely diagnosis and management. Due to the insidious clinical presentation, subtle nature of imaging findings, and complex anatomy of the skull base, diagnosing cerebrovascular injuries and their complications poses considerable challenges. This article offers a comprehensive review of skull base anatomy and pathophysiology pertinent to recognizing cerebrovascular injuries and their complications, up-to-date screening criteria and imaging techniques for assessing these injuries, and a case-based review of the spectrum of cerebrovascular complications arising from skull base trauma. This review will enhance understanding of cerebrovascular injuries and their complications from blunt skull base trauma to facilitate diagnosis and timely treatment.

Abstract
Orbital pathologies can be broadly classified as ocular, extraocular soft-tissue (non-neoplastic and neoplastic), osseous, and traumatic. In this paper, we discuss the key imaging features and differential diagnoses of congenital and developmental lesions (dermoid cyst, dermolipoma), infective and inflammatory pathologies (pre-septal cellulitis, orbital cellulitis, optic neuritis, chalazion, thyroid ophthalmopathy, orbital pseudotumor), and non-neoplastic vascular anomalies (venous malformation, lymphatic malformation, carotid-cavernous fistula), emphasizing the key role of CT and MRI in the imaging work-up. In addition, we highlight the adjunctive role of ocular ultrasound in the diagnosis of dermoid cyst and chalazion, and discuss the primary role of ultrasound in the diagnosis of vascular malformations.

Abstract
Patients presenting with visual disturbances often require a neuroimaging approach. The spectrum of visual disturbances includes three main categories: vision impairment, ocular motility dysfunction, and abnormal pupillary response. Decreased vision is usually due to an eye abnormality. However, it can also be related to other disorders affecting the visual pathway, from the retina to the occipital lobe. Ocular motility dysfunction may follow disorders of the cranial nerves responsible for eye movements (ie, oculomotor, trochlear, and abducens nerves); may be due to any abnormality that directly affects the extraocular muscles, such as tumor or inflammation; or may result from any orbital disease that can alter the anatomy or function of these muscles, leading to diplopia and strabismus. Given that pupillary response depends on the normal function of the sympathetic and parasympathetic pathways, an abnormality affecting these neuronal systems manifests, respectively, as pupillary miosis or mydriasis, with other related symptoms. In some cases, neuroimaging studies must complement the clinical ophthalmologic examination to better assess the anatomic and pathologic conditions that could explain the symptoms. US has a major role in the assessment of diseases of the eye and anterior orbit. CT is usually the first-line imaging modality because of its attainability, especially in trauma settings. MRI offers further information for inflammatory and tumoral cases. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Abstract
Orbital lesions compose a heterogeneous group of pathologies that often present with non-specific imaging findings on conventional magnetic resonance imaging (MRI) sequences (T1-and T2-weighted). Accordingly, the application of diffusion MRI offers an opportunity to further distinguish between lesions along this spectrum. Diffusion-weighted imaging (DWI) represents the simplest and most frequent clinically utilised diffusion imaging technique. Recent advances in DWI techniques have extended its application to the evaluation of a wider spectrum of neurological pathology, including orbital lesions. This review details the manifestations of select orbital pathology on DWI and underscores specific situations where diffusion imaging allows for increased diagnostic sensitivity compared to more conventional MRI techniques. These examples also describe preferred management for orbital lesions identified by DWI.

Abstract
Carotid cavernous fistula (CCF) is a condition with abnormal flow from the carotid artery to the cavernous sinus. The characteristic clinical findings are ophthalmic monoplegia, ptosis, exophthalmos, chemosis, Horner's syndrome, facial pain, loss of sensation in the distribution of the trigeminal nerve, and headache. Digital subtraction angiography (DSA) is the gold standard modality for evaluating CCF. An 18-year-old patient came with decreased bilateral visual acuity after a traffic accident. CT angiography was performed on the patient and found a dilated right superior ophthalmic vein. CCF is present in the patient. The DSA procedure was performed on the patient, and embolization was performed on the right ophthalmic vein. On post-embolization angiography, the tubular structure is no longer visible, which is bilateral superior ophthalmic vein dilatation.

Abstract
PURPOSE OF REVIEW Surgical deactivation of migraine trigger sites by extracranial neurovascular decompression has produced encouraging results and challenged previous understanding of primary headaches. However, there is a lack of in-depth discussions on the pathophysiological basis of migraine surgery. This narrative review provides interpretation of relevant literature from the perspective of compressive neuropathic etiology, pathogenesis, and pathophysiology of migraine. RECENT FINDINGS Vasodilation, which can be asymptomatic in healthy subjects, may produce compression of cranial nerves in migraineurs at both extracranial and intracranial entrapment-prone sites. This may be predetermined by inherited and acquired anatomical factors and may include double crush-type lesions. Neurovascular compression can lead to sensitization of the trigeminal pathways and resultant cephalic hypersensitivity. While descending (central) trigeminal activation is possible, symptomatic intracranial sensitization can probably only occur in subjects who develop neurovascular entrapment of cranial nerves, which can explain why migraine does not invariably afflict everyone. Nerve compression-induced focal neuroinflammation and sensitization of any cranial nerve may neurogenically spread to other cranial nerves, which can explain the clinical complexity of migraine. Trigger dose-dependent alternating intensity of sensitization and its synchrony with cyclic central neural activities, including asymmetric nasal vasomotor oscillations, may explain the laterality and phasic nature of migraine pain. Intracranial allodynia, i.e., pain sensation upon non-painful stimulation, may better explain migraine pain than merely nociceptive mechanisms, because migraine cannot be associated with considerable intracranial structural changes and consequent painful stimuli. Understanding migraine as an intracranial allodynia could stimulate research aimed at elucidating the possible neuropathic compressive etiology of migraine and other primary headaches.

Abstract
BACKGROUND Cavernous hemangioma represents a rare vascular malformation usually located in the cavernous sinus that could be exceptionally found purely in the intrasellar region. The clinical presentation of intrasellar cavernous hemangioma (ICH), frequently variable and unspecific, poses the patient at risk for misdiagnosis and the clinical consequences of suboptimal treatment. We present a case of ICH and describe the advanced magnetic resonance imaging (MRI) features that should direct toward the clinical suspicion of ICH. CASE PRESENTATION An illustrative case of a 61-year-old man complaining of recurrent headaches and diagnosed with a sellar and parasellar lesion was reported and used as a cue to discuss MRI imaging sequences that may aid in the distinction of ICH from pituitary adenoma and other skull base lesions. Heterogeneous enhancement followed by intense homogeneous enhancement at the dynamic contrast-enhanced sequences ("fill-in" phenomenon), absence of blooming signs at the gradient recalled echo (GRE) T2*-weighted and/or susceptibility-weighted imaging (SWI) MRI sequences, and elevated apparent diffusion coefficient (ADC) values usually characterize ICH instead of pituitary adenoma. CONCLUSION Advanced MRI imaging plays an invaluable role in the pre-operative characterization of skull base lesions. Although rare, skull base surgeons should be aware of the ICH in the differential diagnosis process in case of the intrasellar lesion, and a tailored MRI examination should be performed to direct the patient toward the safest and optimal treatment.

Abstract
Anaplastic lymphoma kinase (ALK)-positive histiocytosis is an uncommon condition, recently considered a separate condition from other histiocytosis by WHO 5th edition. It can involve intracranial structures. This manuscript describes a case of ALK-positive histiocytosis of the cavernous sinus, focusing on the radiologic and pathologic presentation of the entity. Our case had MRI manifestations mimicking meningioma, metastasis, and Langerhans histiocytosis. On CT imaging, benign osseous remodeling of the cavernous sinus was detected, which can be helpful in differentiating it from more common meningioma.

Abstract
The sellar region represents a complex anatomical area, composed of multiple structures of different embryological derivation, including the skull base and the pituitary gland, along with vascular, nervous, and meningeal structures. Masses arising in this region include benign and malignant lesions arising from the pituitary gland itself, but also from vestigial embryological residues or surrounding tissues, that may require different therapeutic approaches. While assessing sellar region masses, the combination of clinical presentation and imaging features is fundamental to define hypotheses about their nature. MR represents the imaging modality of choice, providing information about the site of the lesion, its imaging features, and relation with adjacent structures, while CT is useful to confirm the presence of lesion calcifications or to reveal tumor invasion of bony structures. The aim of this pictorial review is to provide an overview of the common neoplasms and tumor-like conditions of the sellar region, according to the 2021 WHO Classification of Tumors of the Central Nervous System (fifth edition), with an emphasis on the radiologic-pathologic correlation. After a brief introduction on the anatomy of this region and the imaging and pathological techniques currently used, the most relevant MRI characteristics, clinical findings, and pathological data, including histologic and molecular features, will be shown and discussed, with the aim of facilitating an appropriate differential diagnosis among these entities.

Abstract
Abstract
Background
Cavernous haemangioma of the cavernous sinus is an uncommon vascular malformation. It is often confused with other parasellar masses like schwannomas and meningiomas due to overlap in imaging appearance. It is important to pre-operatively diagnose this condition as it is associated with severe intra-operative bleeding.
Case presentation
Here, we report a case of an octogenarian female who presented with left sided progressive ptosis and diminution of vision for one year. Cross-sectional imaging includes computed tomography and magnetic resonance imaging which were not conclusive of cavernous sinus haemangioma. Digital subtraction angiography was done which showed a vascular blush. After corroborating the findings of these imaging investigations, a diagnosis of cavernous sinus haemangioma was concluded. Patient underwent surgery which showed a hypervascular mass. Histopathology was consistent with the imaging diagnosis. Patient was discharged in good stable condition and doing well and is on follow-up in Neurosurgery Out-Patient Department.
Conclusions
The cavernous sinus Haemangiomas are uncommon benign vascular masses. They pose a diagnostic challenge when seen in the parasellar region as the imaging findings of a haemangioma, meningioma and schwannoma in this location can have a significant overlap in the imaging findings. Cross-sectional imaging, digital subtraction angiography and nuclear imaging help in pre-operative diagnosis which is a crucial as the surgery is associated with significant blood loss.

Abstract
Cross-sectional imaging with computed tomography (CT) and MRI are diagnostic examinations useful in the diagnosis of painful ophthalmologic disorders and their potential complications. CT is a first-line imaging study for suspected orbital infections, particularly useful in differentiating preseptal cellulitis and orbital cellulitis and detecting complications such as orbital abscess. When compared with CT, MRI is better for orbital soft tissue evaluation, particularly useful for optic neuritis, ocular diseases such as endophthalmitis, and invasive fungal rhinosinusitis with orbital involvement. CT angiography is the preferred noninvasive imaging modality for the detection and classification of carotid cavernous fistula.

Abstract
INTRODUCTION Gruber's ligament (GL), a surgical landmark, extends from the lateral upper clivus to the petrous apex (PA), forming the superior boundary of Dorello's canal (DC). It overlies the interdural segment of the abducens nerve (CN VI). High-resolution 3D skull base MRI (SB-MRI) demonstrates anatomic details visible to the surgeon, but not well seen on traditional cross-sectional imaging. The aim of this study was to demonstrate visualization of the GL and its relationship to CN VI utilizing contrast enhanced high-resolution SB-MRI. METHODS Two neuroradiologists retrospectively reviewed in consensus the SB-MRIs of 27 skull base sides, among 14 patients. GL detection rate, confidence of detection, and GL length were recorded. When GL was successfully identified, the position of the interdural segment of CN VI within DC was recorded. RESULTS GL was readily identified in 16 skull base sides (59%), identified with some difficulty in 2 skull base sides (7%), and failed to be identified in 9 skull base sides (33%). The mean GL length was 7.1 mm (4.5-9.3 mm). Among the 18 cases where GL was successfully identified, CN VI was readily identified in all cases (100%), coursing the lateral third of DC in 72% of sides, and middle third in the remaining 28% of sides. CONCLUSION GL can be identified in approximately two-thirds of cases utilizing 3D high resolution SB-MRI. CN VI passes most commonly along the lateral third of DC. This is the first report demonstrating visualization of GL and its relation to CN VI, on imaging.

Abstract
Background
The cavernous sinus is a complex space composed of extradural venous plexus within dural folds. Several important structures like the carotid artery, cranial nerves, and sympathetic nerve fibers traverse through this space. Radiological diagnosis may not be definitive and in the context of discordance between clinical and neuroimaging diagnosis, histopathological evaluation becomes essential for diagnosis and management. Literature on the pathological spectrum of lesions is scarce as, with a shift in the treatment paradigm, most small lesions of cavernous sinus are treated with radiosurgery. However, surgical management still plays a role for larger lesions and in radiologically ambiguous cases for planning the definitive management.
Materials and Methods
We retrospectively reviewed all surgically resected lesions of the cavernous sinus over the last two decades (1998–2019). The clinical presentation, neuroimaging features, and histopathological findings were reviewed. Lesions extending from sella and other adjacent areas were excluded.
Results
Thirty-eight cases of isolated cavernous sinus mass lesions were diagnosed over the last two decades (1998–2019). Cavernous hemangiomas (19 cases, 50%) constituted the most frequent pathology, followed by aspergilloma, meningioma, schwannoma, metastatic adenocarcinoma, chondrosarcoma, and chordoma. Overall, 29.4% (10/34) could not be accurately diagnosed on neuroimaging. Of these, four cases of cavernous hemangiomas were mistaken for either meningioma (three cases) or schwannoma (one case). Neither chordoma nor chondrosarcoma was suspected.
Conclusion
This is the first study in literature, enumerating the pathological and imaging spectrum of surgically resected cavernous sinus lesions. Cavernous hemangiomas, metastases and chordomas, and chondrosarcoma posed the greatest difficulty in diagnosis on neuroimaging and the reasons for the same are analyzed. In the context of clinical and neuroimaging discordance in diagnosis, pathological characterization becomes essential for appropriate and timely management.

Abstract
Abstract
Background
Craniofacial monostotic fibrous dysplasia is a rare and usually incidental bone pathology. CT comes to the fore in the diagnosis of monostotic fibrous dysplasia and MRI is used to show its relationship to the neighboring structures. Cavernous sinus inflammation may occur due to infectious and inflammatory causes. Inflammation of unknown cause is called Tolosa–Hunt syndrome.
Case presentation
In this case report, we presented cavernous sinus inflammation accompanying fibrous dysplasia in a 35-year-old female patient, which was seen for the first time in the literature.
Conclusions
The contrast-enhanced MR images are very important for the diagnosis and follow-up of the patient, in the rare presence of association we have shown in this case.

Abstract
The petrous apex (PA) is involved in a myriad of pathological conditions, some of which are exclusive in children. Diagnosis may be difficult due to vague clinical presentation, and local examination is challenging owing to its inaccessible location. This is further complicated by multiple unfused sutures and ongoing PA pneumatization in children. Cross-sectional imaging is vital for the evaluation of the PA lesions, due to their precarious location and proximity to the major neurovascular structures. Several classification systems have been proposed for these lesions based on their site of origin, solid or cystic appearance, surgical or non-surgical (no touch lesions) management, and benign or malignant nature. In this article, we emphasize the distinctive role of different cross-sectional imaging modalities in the diagnosis of pediatric PA lesions, with special attention to normal variants that should not be mistaken for pathology. We also propose a radiological classification and algorithmic approach to aid in the precise diagnosis and facilitate appropriate management of the various PA lesions in children.

Abstract
The role of magnetic resonance imaging (MRI) in diplopia is to diagnose various diseases that occur along the neural pathway governing eye movement. However, the lesions are frequently small and subtle and are therefore difficult to detect on MRI. This article presents representative cases of diseases that cause diplopia. The purpose of this article was to 1) describe the anatomy of the neural pathway governing eye movement, 2) recommend optimal MRI targets and protocols for the diagnosis of diseases causing diplopia, 3) correlate MRI findings with misalignment of the eyes (i.e., strabismus), and 4) help familiarize the reader with the imaging diagnosis of diplopia.

Abstract
The sellar, suprasellar, and parasellar space contain a vast array of pathologies, including neoplastic, congenital, vascular, inflammatory, and infectious etiologies. Symptoms, if present, include a combination of headache, eye pain, ophthalmoplegia, visual field deficits, cranial neuropathy, and endocrine manifestations. A special focus is paid to key features on CT and MRI that can help in differentiating different pathologies. While most lesions ultimately require histopathologic evaluation, expert knowledge of skull base anatomy in combination with awareness of key imaging features can be useful in limiting the differential diagnosis and guiding management. Surgical techniques, including endoscopic endonasal and transcranial neurosurgical approaches are described in detail.

Abstract
Skull base infections are uncommon but can be life threatening without timely recognition. Imaging plays a crucial role because symptoms can be vague and nonlocalizing. Necrotizing otitis externa in diabetic or immunocompromised patients is the commonest cause of skull base osteomyelitis (SBO), followed by sinogenic infections and idiopathic central SBO. Multiparametric magnetic resonance (MR) and high-resolution CT are the mainstays for establishing a diagnosis and estimating disease extent, with MR being superior in ascertaining marrow and soft tissue involvement. Monitoring treatment response, of which imaging is a fundamental part, is challenging, with emerging promising imaging tools.

Abstract
La trombosis de los senos cavernosos (TSC) corresponde a una entidad vascular poco usual, asociada con alta morbimortalidad y secuelas neurológicas. La etiología más frecuente son los procesos infecciosos a nivel de cabeza y cuello, que sirven como puerta de entrada para diferentes microorganismos, generando una respuesta inflamatoria que desencadena el evento trombótico. La enfermedad periodontal caracterizada por inflamación gingival, pérdida de tejido conectivo circundante y eventual del diente está asociada con el desarrollo de enfermedades sistémicas secundarias a los patógenos periodontales y mediadores inflamatorios producidos en la cavidad oral. Estos pueden diseminarse y producir complicaciones por contigüidad como eventos trombóticos a nivel del sistema nervioso central. A continuación, se presenta el caso clínico de un paciente que desarrolló una TSC bilateral después de ser sometido a un procedimiento periodontal.

Abstract
Objective The widely accepted treatment option of a traumatic carotid cavernous fistula (TCCF) has been detachable balloon or coils based fistula occlusion. Recently, covered stent implantation has been proving an excellent results. The purpose of this study is to investigate our experiences with first line choice of covered stent implantation for TCCF at level 1 regional trauma center.
Methods From November 2004 to February 2020, 19 covered stents were used for treatment of 19 TCCF patients. Among them, 15 cases were first line treatment using covered stents. Clinical and angiographic data were retrospectively reviewed.
Results Procedures were technically successful in all 15 cases (100%). Immediate angiographic results after procedure were total occlusion in 12 patients (80%). All patients except two expired patients had image follow-up (mean 15 months). Recurred symptomatic three patients underwent additional treatments and achieved complete occlusion. Mean clinical follow-up duration was 32 months and results were modified Rankin Scale 1–2 in five, 3–4 in five, and 5 in three patients.
Conclusion The covered stent could be considered as fist line treatment option for treating TCCF patients especially in unstable vital sign. Larger samples and expanded follow-up are required to further develop their specifications and indications.

Abstract
Pathology involving the Cavernous Sinus (CS), generally referred to as Cavernous Sinus Syndrome (CSS), can arise from vascular disorders, neoplasms, infections, and non-infectious inflammatory disorders. An acute understanding of the CS and its regional anatomical structures is therefore pertinent in expounding the highly variable clinical manifestations seen in CSS as well as laying the groundwork for surgical intervention. Though the neuroanatomy of the cavernous sinus has been substantially chronicled in literature, their correlation to clinical signs has only been minimally described. This narrative review serves to address this knowledge gap and aims to comprehensively correlate the clinical manifestations of CSS with the relevant neuroanatomy, thereby allowing medical practitioners to better navigate the diagnostic quandary. We conducted a scoping review of the literature concerning CS anatomy and CSS, complied through MEDLINE/OVID and cross-referencing of articles on PubMed and Google Scholar with the keywords cavernous sinus, cavernous sinus syndrome, clinical signs/manifestations, neuroanatomy, CS pathology, Cavernous Sinus Thrombus (CST) and cavernous sinus neoplasms/tumours.

Abstract
Septic cavernous sinus thrombosis (SCST) is a rare, yet severe, process typically arising from infections of the paranasal sinuses (predominately ethmoid and/or sphenoid sinusitis) and less commonly, otogenic, odontogenic, and pharyngeal sources. Clinical symptoms of SCST arise from obstruction of venous drainage from the orbit and compression of the cranial nerves within the cavernous sinus. In the preantibiotic era SCST was considered universally fatal (80-100%); however, with the introduction of antibiotics the overall incidence, morbidity, and mortality of SCST have greatly declined. In spite of dramatic improvements, morbidity and mortality remain high, with the majority of patients experiencing neurological sequalae, highlighting the severity of the disease and the need for prompt recognition, diagnosis, and treatment. Here we review of the literature on SCST with a focus on the current recommendations and recent evidence for diagnostic and medical management of this condition.

[PMID: 33579209 PMCID: PMC7881607 DOI: 10.1186/s12880-021-00556-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 01/28/2021] [Accepted: 02/01/2021] [Indexed: 12/25/2022] Open
Abstract
Background Primary lymphoma of the cavernous sinus is a rare form of extranodal non-Hodgkin lymphoma, of which very few cases have been reported in the published literature. This report presents the MRI findings with apparent diffusion coefficient (ADC) value in an exceedingly rare primary marginal zone B-cell lymphoma (MZBCL) of the cavernous sinus. Case presentation The case in this study is a 59-year-old immunocompetent male patient with a 2-month history of right ptosis and blurred vision. Right third cranial nerve palsy and binocular diplopia were observed upon neurological examination. Preoperative brain CT showed an extra-axial enhancing mass lesion in the right cavernous sinus. On MRI, ipsilateral internal carotid arterial encasement was noted without causing stenosis of the vessel. Isointense signal on T1-weighted and T2-weighted images, homogeneous contrast enhancement, and diffusion restriction were also observed. The mean ADC value of the tumor is 0.64 × 10–3 mm2/s (b value = 1000 s/mm2). Subtotal resection of the tumor was performed, and improvement of clinical symptoms were observed. The pathologic diagnosis of MZBCL was established by immunohistochemical examinations. Conclusions Primary MZBCL of the cavernous sinus is exceedingly rare, and preoperative confirmation poses a major challenge with CT and conventional MRI only. In this case, preoperative quantitative ADC value is shown to offer valuable additional information in the diagnostic process.

Abstract
Background and Purpose Contrast enhancement of the oculomotor nerve in MRI was recently noticed in patients with clinical ischemic isolated oculomotor nerve palsy (iIONP). The opinions about whether this is a sign of inflammation and whether or not to administer steroids vary between doctors. The study aimed to determine the associations between this enhancement and vascular-disease risk factors (VRFs) and inflammatory factors in iIONP patients. Methods The study recruited patients who had experienced iIONP during the previous 2 years. They were divided into groups A and B based on whether or not they exhibited an enhanced oculomotor nerve in MRI of the cavernous sinus using thin-section, fat-suppressed, and contrast-enhanced sequences. VRFs, inflammatory factors, and improvement scores were compared between the two groups. Results Most (71.1%) of the 45 included iIONP patients had enhanced oculomotor nerves in MRI. VRFs, periorbital pain, elevated C-reactive protein and erythrocyte sedimentation rate, the neutrophil-to-lymphocyte ratio, and the platelet-to-lymphocyte ratio were not significantly associated with the enhancement. Four of the five patients in group A exhibited an elevated cerebrospinal fluid (CSF) IgG synthesis rate. The improvement score of eight patients who received 80 mg of methylprednisolone in addition to the routine therapy was not significantly different from the scores of the other patients (p=0.485). Conclusions More than half of the iIONP patients had an enhanced oculomotor nerve in MRI. A few of them also had elevated CSF IgG synthesis rate, but no further evidence for inflammation was found. The administration of steroids seemed to have no benefit other than increasing the blood glucose level.

Abstract
There are a wide variety of inflammatory, infectious, and cystic lesions which may lead patients to seek acute care for facial swelling. Computed tomography (CT) has become the mainstay for imaging in the urgent/emergent setting. However, magnetic resonance imaging (MRI) can also serve as a powerful problem solving tool in the modern era. As volume continues to increase, a wide variety of facial pathology will be encountered by the emergency radiologist. Recognition of both common and uncommon pathology will assist in diagnosis and value-based care. This article serves as an image-rich review of the many causes of facial swelling with an emphasis on key imaging findings and possible complications.

Abstract
BACKGROUND Time-resolved angiography with interleaved stochastic trajectories (TWIST) is a keyhole imaging with frequent sampling of central k-space data and view-sharing for the peripheral k-space of dynamic phases. IT-TWIST is a technique to reconstruct images with a smaller temporal footprint using the same raw data obtained with TWIST by iterative reconstruction. PURPOSE To compare image quality between TWIST and IT-TWIST in 3D pituitary DCE-MRI. STUDY TYPE Retrospective observation study. POPULATION Fifty-one patients (23 men, 28 women) who underwent 3D pituitary DCE-MRI using TWIST between July 2016 and April 2017. FIELD STRENGTH/SEQUENCE 3T/TWIST and IT-TWIST. ASSESSMENT Visual evaluation was conducted for image quality of delineation of the pituitary stalk and posterior lobe during the early arterial phase, cerebral white matter near the sella turcica, and the mass lesion. Bolus sharpness of the pituitary stalk, posterior lobe, and bilateral cavernous sinus was evaluated on the enhancement slope map calculated from TWIST and IT-TWIST. Temporal stability of intensity of the nonenhanced area was evaluated on temporal standard deviation (SD) maps calculated from TWIST and IT-TWIST. STATISTICAL TESTS Paired t-test or Wilcoxon rank-sum test was used to test the differences between TWIST and IT-TWIST in both visual evaluation and region of interest evaluation. RESULTS Scores of visual evaluations for IT-TWIST were significantly better than those for TWIST (P < 0.001) in all items. Enhancement slope for IT-TWIST was significantly higher than that for TWIST in posterior lobe, and right and left cavernous sinus (P < 0.001). Temporal SD for IT-TWIST was significantly lower than that for TWIST in all items, with statistical significance (P < 0.001). DATA CONCLUSION IT-TWIST yielded better visualization, and better enhancement slope, and less temporal SD compared with TWIST in 3D pituitary DCE-MRI. Evidence Level: 4 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2020;51:1497-1506.
