RESUMEN
There is no standard of care for management of Rathke cleft cysts (RCCs), and protocol for spontaneous rupture or residual capsule fragments is not well documented.Our case involves a Caucasian man in his 80s who presented with muscle weakness, fatigue, bitemporal hemianopia and pain. Further examination demonstrated decreased thyroid and cortisol levels. MRI revealed a 1.6×1.5×1.3 cm sellar homogenous mass with extension into the suprasellar cistern. While the size of the cyst was rather large, a decision was made to follow conservatively with serial MRI. At 3 years, the mass had spontaneously regressed. The patient was asymptomatic without imaging evidence of RCC recurrence at 4-year follow-up.Classic indications for surgical intervention in suprasellar cysts were subtle in our patient and his advanced age made us take a conservative approach. Current data are lacking regarding management of RCCs presenting with endocrine dysfunction. Our case suggests that RCCs presenting with endocrine dysfunction may be managed conservatively with serial imaging-based monitoring.

BACKGROUND: The novel coronavirus disease 2019 (COVID-19) can be associated with various neurological manifestations, including cerebrovascular disease, seizures, peripheral nerve disease, and encephalitis. Intracranial abscess related to COVID-19 is rare but illustrates a serious complication in the studied cases. OBSERVATIONS: The authors report 3 cases of patients presenting with COVID-19 complicated by sinusitis with associated intracranial abscesses. Each patient underwent craniotomy with washout and sinus debridement during their hospital stay. All 3 patients improved to their baseline following treatment. Similar outcomes have been observed in other cases of intracranial abscess associated with COVID-19 infections. LESSONS: Patients achieved significant improvement following evacuation of the abscess and intravenous antibiotics. Further investigation is needed to determine treatment in relation to COVID-19, and the authors recommend following the standard treatment of intracranial abscess at this time.
RESUMEN
BACKGROUND: Inflammatory pseudotumors (IPTs) are rare benign conditions of unknown etiology that can affect any part of the body. IPTs are most commonly associated with Immunoglobulin G4 (IgG4)-related disease. Central nervous system IPTs, especially with pituitary involvement, are even rarer entities. The presence of an IgG4-negative pituitary IPT with simultaneous extracranial involvement has not been reported. CASE REPORT: We present the case of a 41-year-old female with past medical history of rheumatoid arthritis and a diagnosis of pituitary IPT with coexisting sphenoidal (extracranial) involvement mimicking a pituitary macroadenoma at presentation. The patient underwent multiple consecutive biopsies, and an extensive workup prior to establishing the diagnosis. Laboratory work-up showed normal serum IgG4 and unremarkable liver function tests. CONCLUSION: Pituitary lesions with simultaneous sphenoidal involvement in patients with IgG4-negative systemic inflammatory disease should raise the clinical suspicion for intracranial IPTs, as these tumors can mimic aggressive counterparts causing adjacent bony erosion, and local invasion.

BACKGROUND: The computed tomography angiography (CTA) "spot sign" is a well-recognized radiographic marker in primary intracerebral hemorrhage (ICH). Although it has been demonstrated to represent an area of active hemorrhage or contrast extravasation, the exact pathophysiology remains unclear. Vascular mimics of the spot sign have been identified; however, those representing pseudoaneurysm and small vessel aneurysm have rarely been reported. OBSERVATIONS: A 57-year-old female with a past medical history of hypertension and diabetes mellitus presented with 2 weeks of acute-onset, worsening headache. Computed tomography scanning showed a right interior frontal lobe intraparenchymal hemorrhage. CTA demonstrated a punctate focus of hyperattenuation within the hematoma, consistent with a spot sign, which corresponded to a distal anterior cerebral artery pseudoaneurysm on a cerebral angiogram. The patient subsequently underwent emergent resection of the pseudoaneurysm and hematoma evacuation without complications. Her postoperative course was unremarkable without acute concerns or residual symptoms at the 4-month follow-up. LESSONS: The authors present a unique case of a distal anterior cerebral artery pseudoaneurysm presenting as a spot sign in a relatively young patient without underlying vascular disease. Given the need for emergent intervention, intracranial pseudoaneurysm is an important diagnosis to consider in the presence of a spot sign in atypical clinical presentations of primary ICH.
RESUMEN
PURPOSE: Acute subdural hematomas are frequent, highly morbid, and affect all age groups. The most common mechanism of injury is a low-velocity fall, and the incidence of the disease is growing due to increasingly aggressive antithrombotic and anticoagulant therapies. In this study, we aimed to share our experience with the endoscopic-assisted evacuation of acute subdural hematoma, a less invasive procedure compared to standard craniotomy. METHODS: We retrospectively reviewed data of all consecutive patients aged 18 years and older who underwent endoscopic-assisted evacuation of acute-on-chronic subdural hematoma at our institution from 2015 to 2019. Preoperative, intraoperative, postoperative, and follow-up data were collected and reported. Statistical tests were done using Python statistical packages. RESULTS: Of the 35 patients that underwent this procedure, 32 were 18 years and older. The median age was 69.5 years and 37.5% were female. Twenty patients (62.5%) were on antiplatelet therapy, and six patients (18.75%) were on anticoagulants upon presentation. A fall was the most common cause of trauma (71.88%). The median operative time was 107 minutes. The median length of stay in days and Glasgow Coma Scale (GCS) at discharge were 8.5 and 15, respectively. There were no surgical site infections or in-hospital mortality in this series. At the latest follow-up, the median GCS and modified Rankin Scale were 15 and 1, respectively. CONCLUSION: Evacuation of acute-on-chronic subdural hematomas can be performed safely and efficiently via a smaller craniotomy and with the assistance of an endoscope. This may represent a less invasive alternative than standard craniotomy/craniectomy in selected patients.
RESUMEN
OBJECTIVE: Glioblastomas multiforme (GBMs) are the most common primary CNS tumors. Epidemiologic studies have investigated the effect of demographics on patient survival, but the literature remains inconclusive. METHODS: This study included all adult patients with intracranial GBMs reported in the surveillance epidemiology and end results (SEER)-9 population database (1975-2018). The sample consisted of 32,746 unique entries. We forecast the annual GBM incidence in the US population through the year 2060 using time series analysis with autoregressive moving averages. A survival analysis of the GBM-specific time to death was also performed. Multivariate Cox proportional hazards (PH) regression revealed frank violations of the PH assumption for multiple covariates. Parametric models best described the GBM population's survival pattern; the results were compared to the semi-parametric analysis and the published literature. RESULTS: We predicted an increasing GBM incidence, which demonstrated that by the year 2060, over 1,800 cases will be reported annually in the SEER. All eight demographic variables were significant in the univariable analysis. The calendar year 2005 was the cutoff associated with an increased survival probability. A male survival benefit was eliminated in the year-adjusted Cox. Infratentorial tumors, nonmetropolitan areas, and White patient race were the factors erroneously associated with survival in the multivariate Cox analysis. Accelerated Failure Time (AFT) lognormal regression was the best model to describe the survival pattern in our patient population, identifying age >30 years old as a poor prognostic and patients >70 years old as having the worst survival. Annual income >USD 75,000 and supratentorial tumors had good prognostics, while surgical intervention provided the strongest survival benefit. CONCLUSIONS: Annual GBM incidence rates will continue to increase by almost 50% in the upcoming 30 years. Cox regression analysis should not be utilized for time-to-event predictions in GBM survival statistics. AFT lognormal distribution best describes the GBM-specific survival pattern, and as an inherent population characteristic, it should be implemented by researchers for future studies. Surgical intervention provides the strongest survival benefit, while patient age >70 years old is the worst prognostic. Based on our study, the demographics such as gender, race, and county type should not be considered as meaningful prognostics when designing future trials.

OBJECT: Surgical site infection (SSI) after cranioplasty can result in unnecessary morbidity. This analysis was designed to determine the risk factors of SSI after cranioplasty in patients who received a decompressive craniectomy with the autologous bone for traumatic brain injury (TBI). METHODS: A retrospective review was performed at two level 1 academic trauma centers for adult patients who underwent autologous cranioplasty after prior decompressive craniectomy for TBI. Demographic and procedural variables were collected and analyzed for associations with an increased incidence of surgical site infection with two-sample independent t tests and Mann Whitney U tests, and with a Bonferroni correction applied in cases of multiple comparisons. Statistical significance was reported with a P value of <â0.05. RESULTS: A total of 71 patients were identified. The mean interval from craniectomy to cranioplasty was 99âdays (7-283), and 3 patients developed SSIs after cranioplasty (4.2%). Postoperative drain placement (Pâ>â0.08) and administration of intrawound vancomycin powder (Pâ=â0.99) were not predictive of infection risk. However, a trend was observed suggesting that administration of prophylactic preoperative IV vancomycin is associated with a reduced infection rate. CONCLUSIONS: The SSI rate after autologous cranioplasty in TBI patients is lower than previously reported for heterogeneous groups and indications, and the infection risk is comparable to other elective neurosurgical procedures. As such, the authors recommend attempting to preserve native skull and perform autologous cranioplasty in this population whenever possible.

Microglia are the primary immune cell of the CNS, comprising 5-20% of the â¼60 billion neuroglia in the human brain. In the developing and adult CNS, they preferentially target active neurons to guide synapse maturation and remodeling. At the same time, they are the first line of defense against bacterial, fungal, and viral CNS infections. Although an extensive literature details their roles in rodents, less is known about how they function in humans because of the difficulty in obtaining tissue samples and the understandable inability to extensively study human microglia in situ. In this study, we use recent advances in the study of brain microenvironments to establish cultures of primary human microglia in a serum-free medium. Postsurgical samples of human brain were enzymatically and mechanically dissociated into single cells, and microglia were isolated at high purity by positive selection using CD11b Ab-coated microbeads. The CD11b+ cells were plated on poly-l-lysine-coated surfaces and bathed in serum-free DMEM/F12 supplemented with three essential components (TGF-ß, IL-34, and cholesterol). Under these conditions, microglia assumed a ramified morphology, showed limited proliferation, actively surveyed their surroundings, and phagocytosed bacterial microparticles. In the presence of LPS, they assumed a more compact shape and began production of proinflammatory cytokines and reactive oxygen species. LPS on its own triggered release of TNF-α, whereas release of IL-1ß required costimulation by ATP. Thus, human microglia maintained in a defined medium replicate many of the characteristics expected of native cells in the brain and provide an accessible preparation for investigations of human microglial physiology, pharmacology, and pathophysiology.

BACKGROUND: Multifocal rosette-forming glioneuronal tumors (RGNTs) are challenging to manage. Gross total resection is often impossible, and data on adjunctive therapies are limited. We reviewed cases of multifocal RGNTs in the literature with special focus on dissemination patterns and management. METHODS: A literature review was conducted using PubMed and the key words "(multifocal OR multicentric OR satellite OR dissemination) AND glioneuronal." RESULTS: There were 21 cases of multifocal RGNTs identified. Follow-up was available in 18 cases at a median of 17 months. Progression-free survival and overall survival at 1 year were 84% and 94%, respectively. Of all cases, 43% had cerebrospinal fluid (CSF) dissemination, 48% had intraparenchymal spread, and 10% had both. The presence of CSF dissemination led to palliative care and/or death in 20% of cases (n = 2). None of the cases with intraparenchymal spread progressed. Radiotherapy was used in 50% of cases with CSF dissemination, chemotherapy was used in 20%, and CSF shunting was used in 36%. No tumors with intraparenchymal spread required adjunctive therapy or shunting. CONCLUSIONS: RGNTs with CSF dissemination are more likely to behave aggressively, and early adjunctive therapies should be discussed with patients. Tumors with intraparenchymal spread grow slowly, and maximal safe resection followed by observation is likely sufficient in the short term. Long-term behavior of multifocal RGNTs is still unclear.

OBJECTIVE: Penetrating brain injury (PBI) is the most lethal of all firearm injuries, with reported survival rates of less than 20%. The projectile trajectory (PT) has been shown to impact mortality, but the significant lobar tracks have not been defined. The aim of this retrospective case-control study was to test for associations between distinct ballistic trajectories, missile types, and patient outcomes. METHODS: A total of 243 patients who presented with a PBI to the Saint Louis University emergency department from 2008 through 2019 were identified from the hospital registry. Conventional CT scans combined with 3D CT reconstructions and medical records were reviewed for each patient to identify distinct PTs. RESULTS: A total of 65 ballistic lobar trajectories were identified. Multivariable regression models were used, and the results were compared with those in the literature. Penetrating and perforating types of PBI associated with bitemporal (t-statistic = -2.283, p = 0.023) or frontal-to-contralateral parietal (t-statistic = -2.311, p = 0.025) projectile paths were universally found to be fatal. In the group in which the Glasgow Coma Scale (GCS) score at presentation was lower than 8, a favorable penetrating missile trajectory was one that involved a single frontal lobe (adjusted OR 0.02 [95% CI 0.00-0.38], p = 0.022) or parietal lobe (adjusted OR 0.15 [95% CI 0.02-0.97], p = 0.048). Expanding or fragmenting types of projectiles carry higher mortality rates (OR 2.53 [95% CI 1.32-4.83], p < 0.001) than do nondeformable missiles. Patient age was not associated with worse outcomes when controlled by other significant predictive factors. CONCLUSIONS: Patients with penetrating or perforating types of PBI associated with bitemporal or frontal-to-contralateral parietal PTs should be considered as potential donor candidates. Trauma patients with penetrating missile trajectories involving a single frontal or parietal lobe should be considered for early neurosurgical intervention, especially in the circumstances of a low GCS score (< 8). Surgeons should not base their decision-making solely on advanced patient age to defer further treatment. Patients with PBIs caused by nondeformable types of projectiles can survive multiple simultaneous intracranial missile trajectories.
RESUMEN
BACKGROUND: Gliadel placement in glioblastoma resection, particularly with concurrent chemoradiation, has demonstrated an improvement in survival. There have been several reported adverse effects, some of which lend to significantly increased morbidity and mortality. With only two other cases described in literature, cerebral vasospasm secondary to carmustine-impregnated wafers is an extremely rare side effect. CASE DESCRIPTION: We report the case of a 51-year-old female who presented with the left lower limb paresis 8 days after high-grade glioma resection provoked by carmustine wafer placement. CONCLUSION: We urge surgeons to reconsider placement of carmustine wafers in nations where the surgical resection cavity includes exposed large cerebral vasculature. We also propose the early identification of this devastating complication in the postoperative period by maintaining a high clinical suspicion and prompt utilization of computed tomography and digital subtraction angiography in the management and treatment of these patients accordingly.
RESUMEN
OBJECTIVE: We present the application of the BrainPath endoport-assisted microsurgical device (EAMD) as a treatment modality for patients with severe intraventricular hemorrhage (IVH) secondary to spontaneous supratentorial intracerebral hemorrhage (sICH). METHODS: Patients with severe secondary IVH (defined as Graeb score [GS] >6) who presented to Saint Louis University Hospital, St. Louis, Missouri, United States, from 2017 to 2019 were treated with the minimally invasive approach for IVH evacuation using the atraumatic BrainPath aspiration system. RESULTS: Three patients (2 men and 1 woman) with a mean age of 54 years were included in this study. The mean preoperative GS was 10.0 with a modified GS of 23.3. The mean postoperative GS was 4.0 (P = 0.001) with a modified GS of 10.67 (P = 0.001). There were no complications related to the surgery itself in any of the reported cases. CONCLUSIONS: BrainPath EAMD evacuation of severe IVH secondary to sICH appears to be a safe and effective treatment modality that significantly increases the extent of IVH clearance, which could also lead to improved long-term patient outcomes.

BACKGROUND: Developments in frameless neuronavigation and tubular retractors hold the potential for minimizing iatrogenic injury to the overlying cortex and subcortical tracts, with improved access to the ventricular system. The objective of the present study was to evaluate the surgical outcomes after resection of third ventricular colloid cysts using an integrated neuronavigation and channel-based approach. METHODS: We performed a multicenter retrospective analysis of surgical Outcomes after surgical resection of third ventricular colloid cysts via a transtubular trans-sulcal approach. RESULTS: A total of 16 patients were included, with a mean age of 42 years (range, 23-62 years). The mean maximum diameter of cysts was 14 mm (range, 7-28 mm), and preoperative hydrocephalous was present in 12 patients (75%). Gross total resection was achieved in all 16 cases. Of the 12 patients, 4 (25%) had undergone septum pellucidotomy, in addition to cyst resection. No case had required conversion to open craniotomy. No perioperative mortalities occurred. Three patients (18.8%) had developed transient memory deficits, 1 of whom had also developed a pulmonary thromboembolism. The median length of hospital stay was 4 days (range, 2-18 days). All the patients reported resolution of preoperative symptoms at the 1-month follow-up examination. Only 1 patient (6.25%) had required insertion of a ventriculoperitoneal shunt. The median follow-up duration was 6.5 months (range, 3-24 months), and no recurrences were observed. CONCLUSION: Use of a channel-based navigable retractor provided a minimal trans-sulcal approach to third ventricular colloid cysts with the benefit of bimanual surgical control in an air medium for definitive resection of third ventricular colloid cysts.

OBJECTIVE: To investigate if the implementation of white matter (WM) fiber tractography by diffusion tensor imaging in presurgical planning for supratentorial tumors proximal to eloquent WM tracts can alter a neurosurgeon's operative strategy. METHODS: A retrospective review was conducted of patients with supratentorial brain tumors within eloquent WM tracts who underwent diffusion tensor imaging (DTI) tractography as part of their preoperative assessment. These patients were classified into 3 different DTI groups per the radiology reports: group 1, intact WM tracts; group 2, deviated and/or displaced WM bundles; and group 3, patients with an established WM injury (interrupted and/or destroyed tracts). A blinded prospective behavioral study followed, in which 4 neurosurgeons reviewed the preoperative images at 2 different times (magnetic resonance imaging without DTI, followed by a review of the DTI). They provided estimations about the DTI group of each individual eloquent WM category in every patient, and their planned surgical approach. RESULTS: Fifteen patients (mean age, 58.3 years) were included in the study. The neurosurgeons provided a correct DTI group estimation in 53%, 60%, and 57% of the cases that involved motor/sensory pathway tracts, optic tracts, and language tracts, respectively. The neurosurgeons underestimated DTI group 3 in the motor category and in the optic category 75% of the time. DTI did not alter the planned surgical approach. CONCLUSIONS: DTI WM tractography helped neurosurgeons to correctly identify patients with interrupted motor and optic pathway tracts so they could be more aggressive with the extent of tumor resection, despite its inability to alter the operative approach.

Primary intraosseous cavernous hemangiomas are rare skull lesions that are not typically known to involve the orbital bones or the dura. We describe a rare case of a fronto-orbital bone cavernous hemangioma with extension into the dura. A 68-year-old female presented with a one-year history of diplopia with discomfort around her left orbit. Magnetic resonance images demonstrated a mass in the left frontal skull extending into the orbital rim. The patient underwent a craniotomy for tumor resection. Dural invasion was found intraoperatively. Gross total resection and reconstruction were achieved. On the postoperative follow-up, the patient was asymptomatic. Primary calvarial intraosseous cavernous hemangiomas are most commonly located in the frontal and parietal bones. These lesions typically involve only the outer table of the skull. In lesions involving the orbit and dura, excision with cranioplasty can provide symptomatic relief with good cosmetic outcomes.
RESUMEN
Cutaneous spindle cell malignancy is associated with a broad differential diagnosis, particularly in the absence of a known primary melanocytic lesion. We present an unusually challenging patient who presented with clinical symptoms involving cranial nerves VII and VIII and a parotid-region mass, which was S100-positive while lacking in melanocytic pigment and markers. Over a year after resection of the parotid mass, both a cutaneous primary lentigo maligna melanoma and a metastatic CP angle melanoma were diagnosed in the same patient, prompting reconsideration of the diagnosis in the original parotid-region mass. Next-generation sequencing of a panel of cancer-associated genes demonstrated 19 identical, clinically significant mutations as well as a high tumor mutation burden in both the parotid-region and CP angle tumors, indicating a metastatic relationship between the two and a melanocytic identity of the parotid-region tumor.
RESUMEN
BACKGROUND: The surgical management of supratentorial intracerebral hemorrhages (ICH) remains controversial due to large trials failing to show clear benefits. Several minimally invasive techniques have emerged as an alternative to a conventional craniotomy with promising results. OBJECTIVE: To report our experience with endoport-assisted surgery in the evacuation of supratentorial ICH and its effects on outcome compared to matched medical controls. METHODS: Retrospective data were gathered of patients who underwent endoport-assisted evacuation between January 2014 and October 2016 by a single surgeon. Patients who were managed medically during the same period were matched to the surgical cohort. Previously published cohorts investigating the same technique were analyzed against the present cohort. RESULTS: Sixteen patients were identified and matched to 16 patients treated medically. Location, hemorrhage volume, and initial Glasgow Coma Scale (GCS) score did not differ significantly between the 2 cohorts. The mean volume reduction in the surgical cohort was 92.05% ± 7.05%. The improvement in GCS in the surgical cohort was statistically significant (7-13, P = .006). Compared to the medical cohort, endoport-assisted surgery resulted in a statistically significant difference in in-hospital mortality (6.25% vs 75.0%, P < .001) and 30-d mortality (6.25% vs 81.25%, P < .001). Compared to previously published cohorts, the present cohort had lower median preoperative GCS (7 vs 10, P = .02), but postoperative GCS did not differ significantly (13 vs 14, P = .28). CONCLUSION: Endoport-assisted surgery is associated with high clot evacuation and decreases 30-d mortality compared to a similar medical group.

BACKGROUND: Traumatic intracranial aneurysms (TICAs) of the posterior circulation in the pediatric populations are rare. Only a few reports in the literature document basilar artery TICA in the pediatric population. These cases were typically associated with a clival fracture and commonly diagnosed weeks to months after trauma. We present a case of a patient with a basilar TICA diagnosed after a motor vehicle collision treated with staged trapping and review of the literature. CASE DESCRIPTION: We present a case of a 14-year-old boy who sustained a high-speed motor vehicle collision and developed a basilar trunk TICA identified on admission. Initially, the patient underwent craniotomy for proximal sacrifice of the basilar artery in hope for spontaneous thrombosis of the aneurysm through flow reversal. Endovascular options were reviewed and felt to be less feasible than surgical trapping. Due to continued filling through the right posterior communicating artery, the second surgery was performed to distally trap the aneurysm. The aneurysm was opened, showing some thrombosis and the absence of flow. Repeat magnetic resonance imaging did not reveal any new infarction, and the patient was discharged with neurologic improvement over time. At 1 year, he was able to ambulate unassisted and had a modified Rankin Scale score of 3. CONCLUSION: Development of a TICA may be more acute than literature previously suggested. Treatment consists of a wide range of options and should be considered, especially in the pediatric population, to prevent rupture. Trapping can be performed safely if adequate collateral flow is present in the setting of a large basilar artery aneurysm.

BACKGROUND: Hemangioblastomas (HGBs) are the most common primary intra-axial posterior fossa tumor in adults. Although spontaneous hemorrhage of these tumors is exceedingly rare, despite their vascular nature, we describe a case of recurrent hemorrhage with associated tonsillar herniation, and demonstrate that a surgical approach can provide a suitable outcome. CASE DESCRIPTION: A 54-year-old female with von Hippel-Lindau (VHL) syndrome presented with acute loss of consciousness and Glasgow Coma Scale (GCS) was 4. Computed tomographic (CT) images demonstrated large volume subarachnoid hemorrhage of the posterior fossa with intraventricular extension and intraparenchymal hemorrhage involving the right cerebellar tonsil. Magnetic resonance imaging (MRI) displayed three lesions in the posterior fossa, two near the hemorrhage site. Patient underwent suboccipital craniectomy with a decent recovery followed by radiosurgery as she refused resection. A second hemorrhage occurred ultimately prompting surgical resection of the three posterior fossa lesions, with a reasonable postoperative course. CONCLUSION: Hemorrhage of HGBs of the posterior fossa can present in conjunction of tonsillar herniation. Re-hemorrhage appears to be likely if prior acute hemorrhage has occurred. A stepwise approach of surgical decompression and resection may provide the best outcome.
RESUMEN
BACKGROUND: Central nervous system vasculitis (CNSV) is a rare disorder, the pathophysiology of which is not fully understood. It involves a combination of inflammation and thrombosis. CNSV is most commonly associated with headache, gradual changes in mental status, and focal neurological symptoms. Diagnosis requires the effective use of history, laboratory testing, imaging, and biopsy. Catheter angiography can be a powerful tool in the diagnosis when common and low-frequency angiographic manifestations of CNSV are considered. We review these manifestations and their place in the diagnostic algorithm of CNSV. SUMMARY: We reviewed the PubMed database for case series of CNSV that included 5 or more patients. Demographic and angiographic findings were collected. Angiographic findings were dichotomized between common and low-frequency findings. A system for incorporating these findings into clinical decision-making is proposed. KEY MESSAGE: CNSV is a diagnostic challenge due to the absence of a true gold standard test. In the absence of such a test, catheter angiography remains a central piece of the diagnostic puzzle when appropriately employed and interpreted.
