RESUMO

La ET es un trastorno multisistémico autosómico dominante que se caracteriza por displasia celular y tisular en varios órganos (cerebro, corazón, piel, ojos, riñones, pulmones) que constituyen una fuente importante de morbilidad y mortalidad. Las manifestaciones comunes incluyen tubérculos corticales, nódulos subependimarios, astrocitomas subependimarios de células gigantes, convulsiones, rabdomiomas cardíacos, AML renales, hamartomas retinianos, linfangioleiomiomatosis pulmonar, angiofibromas faciales, manchas de hojas de ceniza, parches de Shagreen, discapacidad intelectual y trastorno del espectro autista. Se presenta a continuación la resolución de un caso problema grave de una paciente que llega a la consulta al hospital público, con severa incapacidad para mantener la permeabilidad de la válvula nasal externa, a expensas de formación harmartomatosa grave, de años de evolución, fétida y sangrante, decidiéndose tomar conducta quirúrgica urgente y agresiva dada las condiciones de la lesión, la poca colaboración de la paciente y el contexto familiar de la misma que presenta además trastornos conductuales asociados a manifestaciones neurológicas de la enfermedad (retraso madurativo)


ET is an autosomal dominant multisystem disorder characterized by cellular and tissue dysplasia in several organs (brain, heart, skin, eyes, kidneys, lungs) that constitute a major source of morbidity and mortality. Common manifestations include cortical tubercles, subependymal nodules, subependymal giant cell astrocytomas, seizures, cardiac rhabdomyomas, renal AML, retinal hamartomas, pulmonary lymphangioleiomyomatosis, facial angiofibromas, ash leaf spots, shagreen patches, intellectual disability, and autism spectrum disorder. This paper presents the resolution of a serious problem case of a patient who attends the consultation of a public hospital, with severe inability to maintain the patency of the external nasal valve, at the expense of severe harmartomatous formation, of many years of evolution, fetid and bleeding, deciding to undertake urgent and aggressive surgical conduct given the conditions of the lesion, the lack of collaboration of the patient and the family context of the same, which also presents behavioral disorders associated with neurological manifestations of the disease (maturational delay).

RESUMO

PURPOSE: To evaluate the efficacy and safety of transarterial embolization (TAE) with n-butyl cyanoacrylate (nBCA) for juvenile nasopharyngeal angiofibroma (JNA). MATERIALS AND METHODS: A retrospective review was performed on patients with JNA who underwent TAE and endoscopic resection between 2020 and 2022. Patients embolized with nBCA were identified, and those embolized with microspheres were set as the control group. Data on demographics, symptoms, tumor characteristics, blood loss, adverse events, residual disease, and recurrence were collected, and case-control analysis was performed for the 2 groups. Differences in characteristics between the groups were tested using the Fisher exact and Wilcoxon tests. A generalized linear model (GLM) was used to analyze the univariate and multivariate influences on blood loss. RESULTS: Twenty patients were included in this study: 13 in the microsphere group and 7 in the nBCA group. The median blood loss was 400 mL (interquartile range [IQR], 200-520 mL) in the nBCA group and 1,000 mL (IQR, 500-1,000 mL) in the microsphere group (P = .028). The GLM confirmed lower blood loss in the nBCA group (relative risk, 0.58 [0.41-0.83]; P = .01). A residual tumor was found in 1 patient in each group (7.7% vs 14.3%; P = 1.000). Recurrence was not observed in any patient. None of the patients experienced adverse events during embolization. CONCLUSIONS: TAE of advanced JNA with nBCA glue is safe and effective and can significantly reduce intraoperative blood loss compared with microspheres.

RESUMO

Preoperative embolisation of juvenile nasopharyngeal angiofibromas (JNAs) is a well-established treatment that reduces intraoperative blood loss and improves surgical outcomes. While the bulk of arterial supply to the tumour is derived from the external carotid system, some degree of contribution from the internal carotid artery (ICA) is common. ICA branch embolisation in this setting has previously been avoided due to concerns over ischaemic neurological complications, possibly contributing to the increased intraoperative blood loss observed in patients with tumours with ICA supply. There is a marked paucity of reports of embolisation of ICA branches supplying JNA in the medical literature. We present a case of successful embolisation of an aberrant pharyngeal branch of the ascending pharyngeal artery arising from the proximal cervical ICA, which was making a significant contribution to tumour blood supply in a male adolescent with a very large JNA.

RESUMO

OBJECTIVES/HYPOTHESIS: Somatostatin receptors (SSTRs) are highly expressed in neuroendocrine tumors and is exploited for its imaging and treatment. SSTRs expression is also demonstrated in diverse benign and malignant tumor cell types and proliferating peri-tumoral vessels. Similarly, Juvenile Nasopharyngeal Angiofibroma (JNA) expresses different SSTRs and may be utilized for its imaging and treatment using DOTA, 1-Nal3-octreotide (DOTANOC)-PET/CT scan. STUDY DESIGN: Prospective cohort. METHODS: Nineteen clinico-radiologically diagnosed primary JNA patients underwent a 68 Ga-DOTANOC PET-CT scan. Using a dedicated PET/CT scanner, a low-dose head and neck spot CT scan was performed after 45 to 60 minutes of intravenous injection of 2 to 3 mCi(74-111 MBq) of DOTANOC. The primary objective was to assess the intensity and pattern of DOTANOC uptake in these patients. RESULTS: DOTANOC expression was noted in all cases (n = 19) of primary JNA (100%). The mean (SD) DOTANOC SUVmax ratio of tumor and background was 6.9+/-1.4(range, 3.8-9.5). Intra-cranial extension in all 13/19 patients was prominently visualized due to the absence of DOTANOC uptake in the brain. Compared to the background all stages of JNA showed significant DOTANOC uptake (P < .0001). No difference in uptake between advanced-stage tumors and early tumors was noted (P = .47). A statistically non-significant negative trend was noted for decreasing uptake with increasing age (Spearman correlation coefficient, r = -0.19). CONCLUSIONS: This first study of 68 Ga-DOTANOC-PET/CT scan in JNA demonstrates consistent and reliable uptake activity in all patients irrespective of age and stage. This opens up possibilities to physiological diagnostic imaging with a promise of greater specificity and sensitivity and may have applications in ambivalent diagnostic situations such as the detection of recurrence.

RESUMO

OBJECTIVE: Preoperative embolization of juvenile nasopharyngeal angiofibroma (JNA) is usually performed by the occlusion of branches of the external carotid artery (ECA). However, a significant proportion of JNAs also receive blood from the internal carotid artery (ICA). The objective of this study was to report on the feasibility and clinical impact of superselective embolization of ICA branches in complex cases of JNA. METHODS: This was a single-center retrospective study of all patients operated on for JNA between 2000 and 2018. The patients treated with embolization of branches of the ICA were identified. The results in terms of complications, intraoperative blood loss, and rate of residual disease were analyzed and compared to those of a control group of patients treated only with embolization of ECA branches and matched by age, stage, angiographic pattern, surgical approach, and previous surgery. RESULTS: Ninety-two patients were included. Embolization of branches of the ICA was attempted in 14 cases of advanced or recurrent tumors and was ultimately possible in nine cases. There were no complications after embolization. The mean intraoperative blood loss was 1428 mL. Residual disease was found in three cases (33%). There was no significant difference compared with the control group (mean intraoperative blood loss = 1355 mL, residual disease = 4 (44%); all P > .05). CONCLUSION: In this retrospective study, we report the feasibility of superselective embolization of ICA branches in selected cases of JNA. There was no observed benefit of this technique in terms of intraoperative bleeding or decreased risk of residual disease. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E775-E780, 2021.

RESUMO

Juvenile nasopharyngeal angiofibroma (JNA) is a hypervascular, blood-supplied, benign tumour affecting the sinuses, nasal cavity, nasopharynx and the base of the skull. For intraoperative hemostasis, pre-operative embolism is a common and recommended procedure, but it has serious disadvantages, such as additional radiation exposure, anesthesia, and the risk of iatrogenic complications associated with the occlusion of the central artery of the retina, orbital and middle cerebral arteries. This article presents a report on successful radical removal of the widespread SAS without resorting to preoperative embolization, but with intraoperative transnazal endoscopic clipping of the internal maxillary artery (IMA).

RESUMO

We report the case of a patient with recurrent pterygo-palatal angiofibroma and its treatment. A 21-year-old male patient had a long history of recurrent epistaxis with progressive nasal obstruction. He was diagnosed with an angiofibroma centered in the right pterygo-palatine fossa. Initially, he underwent surgical excision with removal of the entire tumor. The evolution was clinically good with no signs of recurrence on the cervico-facial scan of control (CT). Nine months after, he presented a reappearance of epistaxis. A cervico-facial MRI was performed and showed a recurrence of the tumor process, which this time was considered inextirpable, hence the decision to opt for radiotherapy with intensity modulated radiation therapy (IMRT). He has improved clinically with a clear reduction in tumor mass on CT scan. This technique represents an interesting alternative to overcome anatomical complexity of the region, cover the tumor and preserve the organs at risk.

RESUMO

OBJECTIVE: To report trends in Juvenile Nasopharyngeal Angiofibroma (JNA) hospitalizations and identify key factors affecting treatment outcomes and cost of care in JNA patients. METHODS: The Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database was queried for all cases of JNA between the years of 1997 and 2016. Key factors extracted were patient demographics, geographic region, hospital size, teaching status, elective admissions, and number of diagnoses and procedures performed during the hospitalization. These elements were correlated to length of stay (LOS) and cost-per-day (CPD) using a multiple linear regression (MLR). Regional variation in JNA diagnosis and changes in LOS and CPD trends over time were also analyzed. RESULTS: A total of 614 JNA patients were hospitalized in this time period, with a majority of patients identifying as male (98%) and Caucasian/White (55%). The average LOS has decreased by 0.14 day per year since 1997 (P = .0034) whereas the CPD has steadily increased by $2 380 per year (P < .001). MLR analysis revealed that while holding all other factors constant, patients who stayed at teaching hospitals had an increased LOS of 1.7 days (P = .026), but paid $11 961 less per day (P = .05). Regional variation in CPD was found in the Northeast region, where hospitalizations were more expensive by $9 801 per day compared to the South (P = .017). CONCLUSION: These results indicate hospital characteristics, such as teaching status and geographic region, may predict differences in JNA outcomes and cost. Healthcare providers should be cognizant of these variations to ensure optimal patient outcomes and expenditures.

RESUMO

OBJECTIVES/PURPOSE: 1. Understand three different techniques for embolization of juvenile nasal angiofibroma (JNA) and assess their combined efficacy. 2. Perform successful endoscopic intralesional embolization of highly vascular sinonasal neoplasms. METHODS: In this study, we present the case of a 10-year-old male patient diagnosed with juvenile nasal angiofibroma (JNA) who successfully underwent trimodal embolization and resection at a tertiary academic medical center after failed coil embolization in his home country. We examine the clinical details of the case and a review of pertinent literature. RESULTS: Preoperative embolization is common in the treatment of JNA, but there is little consensus as to the proper timeframe and techniques utilized. In our case, preoperative imaging revealed a vascular tumor with intracranial extension consistent with UPMC Stage V JNA. Diagnostic angiogram revealed significant arborization from the internal and external carotid systems. A trimodal embolization technique, utilizing transarterial, percutaneous, and direct endoscopic intralesional injection of n-Butyl Cyanoacrylate (n-BCA) was performed. A two-staged endoscopic and open resection was subsequently performed one week later with minimal blood loss. In our case, combining intralesional embolization with traditional transarterial techniques resulted in an improved operative field and a successful clinical result. CONCLUSION: Embolization of highly vascular sinonasal tumors with n-BCA is not limited to endovascular techniques, but can be safely combined with percutaneous and endoscopic intralesional embolization up to one week prior to surgical resection.

RESUMO

ABSTRACT Locally advanced staged juvenile nasopharyngeal angiofibroma (JNA) traditionally treated with external approaches has been associated with significant morbidities such as blood loss with subsequent blood transfusions, scars, impaired speech, poor swallowing, recurrence and prolonged hospital stays. This case report describes our initial experience in a patient with a locally advanced JNA treated with endonasal endoscopic approach and angio-embolization at Kingston Public Hospital, Jamaica, with subsequent benefits.


RESUMEN El angiofibroma nasofaríngeo juvenil (ANJ) en etapa localmente avanzada, tratado tradicionalmente con enfoques externos, se ha asociado a morbilidades significativas, tales como pérdida de sangre con transfusiones subsecuentes de sangre, cicatrices, trastornos del habla, pobre deglución, recurrencia y estancias hospitalarias prolongadas. Este reporte de caso describe nuestra experiencia inicial con un paciente con ANJ localmente avanzada tratado con un enfoque endonasal endoscópico y angioembolización en el Hospital Público de Kingston, Jamaica, con beneficios subsiguientes.

RESUMO

PURPOSE: To investigate the efficacy and safety of preoperative internal maxillary arterial embolization with gelfoam particles in patients with nasopharyngeal angiofibroma. MATERIALS AND METHODS: We retrospectively reviewed a total of 27 consecutive patients with pathologically confirmed nasopharyngeal angiofibroma from August 2006 to September 2018. Of the 27 enrolled patients, 10 patients received surgical excision alone; 17 patients received preoperative internal maxillary arterial embolization followed by surgical excision. Embolic agents were gelfoam particles. RESULTS: The mean volume of intro-operative blood loss was 385.3 ml in patients with preoperative arterial embolization, which was significantly lower than 1215.0 ml in the patients without preoperative arterial embolization (P < 0.001). The mean surgical time was shorter in patients with preoperative arterial embolization than in the patient without preoperative arterial embolization, but the difference had no statistical significance (205.0 vs 264.5 min, P = 0.064). Neurological complications such as facial palsy or vision loss or hemiplegia were not observed in patients with preoperative arterial embolization. CONCLUSION: Internal maxillary artery embolization with gelfoam particles suffices to provide an effective and safe adjuvant procedure for surgical excision of nasopharyngeal angiofibroma.

RESUMO

PURPOSE OF REVIEW: To illustrate the latest developments and trends in the management of juvenile angiofibroma. RECENT FINDINGS: Endoscopic surgery is currently the primary management strategy for juvenile angiofibroma. Recent reports on the use of multiportal approaches have contributed to further extend its indications. Studies from different countries suggest that the lesion can display variable growth rates not only in relation to patient age. The same concept applies to residual lesions. For this reason, retreatment of persistent juvenile angiofibromas is indicated when serial imaging clearly shows that the lesion is growing. When redo surgery is potentially associated with high morbidity for the critical relationships of the lesion with adjacent structures, stereotactic or intensity-modulated radiation therapy can be an alternative. Early use of MRI in the postoperative course is a highly effective way to detect residual lesions. SUMMARY: Contemporary management of juvenile angiofibroma should primarily rely on endoscopic surgery to obtain radical tumor resection. Recent evidence on the behavior of residual postoperative juvenile angiofibroma and the development of conformal RT techniques have helped to clarify the role of watchful waiting and radiotherapy (RT) as alternatives to aggressive procedures in cases with critical extension of the lesion. Although radical excision is the primary therapeutic objective, the benign nature of juvenile angiofibroma and the reported tendency of small residual lesions to remain stable or involute, especially in postpubertal patients, should always be kept in mind to avoid unnecessary morbidity.

RESUMO

The prostate-specific membrane antigen (PSMA) is highly expressed in prostatic cancer. However, PSMA expression is also noted in various benign and malignant nonprostatic neoplasms in the endothelial cells of tumor-associated neovasculature. We performed Ga-PSMA PET/CT in a 14-year-old boy with juvenile nasal angiofibroma (JNA) to explore its theranostic potential. The scan revealed high uptake in the lesion. Performance of PSMA PET/CT in JNA opens up new frontiers with respect to radiological staging, early recurrence identification, and perhaps even radioligand therapy of residual/recurrent JNAs in the future.

RESUMO

The neoplastic processes localized in the base of the skull and the surrounding region have until recently been considered as the inoperable condition. Juvenile angiofibroma of the base of the skull or angiofibroma of the base of the skull (ABS) is most frequently encountered in the otorhinolaryngological practice. In terms of the histological picture, ABS is a benign tumour having a very complicated structure. The multi-disciplinary approach and the application of up-to-date medical technologies made it possible to obtain an insight into the deepest-lying areas of the base of the skull. A total of 69 patients presenting with juvenile angiofibroma of the base of the skull were available for the examination in the present study. In all this cases, the presence of the tumour was confirmed by the histological studies. Apart from the routine medical examination, all the patients underwent X-ray investigations including computed tomography with 3D-reconstruction, angiography subtracted VRT-reconstruction, and magnetic resonance tomography with contrast enhancement. Moreover, the trans-maxillary-buccal approach was applied with the use of the endovideoscopic equipment. All the patients were discharged from the clinic in the satisfactory condition. Recurrent tumours were documented only in three patients, the lethal cases were altogether absent. The length of the period of follow-up observations amounted to five and more years. It is concluded that the application of the modern medical technologies in the combination with the 'teamwork' interdisciplinary approach greatly contributes to the successful surgical treatment of the pathological processes localized at the base of the skull and the surrounding region.

RESUMO

OBJECTIVE: This study aimed to present the clinical features and surgical outcomes of juvenile nasopharyngeal angiofibroma patients who were surgically treated. METHODS: The medical records of 48 male patients histologically confirmed as having juvenile nasopharyngeal angiofibroma, who underwent transnasal endoscopic surgery between 2005 and 2016, were retrospectively reviewed. RESULTS: The overall recurrence rate was 20.8 per cent; however, the recurrence rate differed significantly between patients diagnosed aged less than 14 years (34.7 per cent) and more than 14 years (8 per cent) (p < 0.05). Advanced-stage tumours (Radkowski stage of IIC or more, and Önerci stage of III or more) were more aggressive than earlier stage tumours (p < 0.05 and p < 0.01, respectively). Pre-operative embolisation significantly prolonged mean hospitalisation duration, but had no effect on intra-operative blood loss in patients with advanced-stage tumours (p < 0.001 and p = 0.09, respectively). CONCLUSION: The findings show that transnasal endoscopic surgery could be considered the treatment of choice for juvenile nasopharyngeal angiofibroma. Patients diagnosed when aged less than 14 years and those with advanced-stage tumours are at risk of recurrence, and should be monitored with extreme care.

RESUMO

BACKGROUND: Tuberous sclerosis is an autosomal dominant genodermatosis characterized by nonmalignant hamartomas in multiple organs. Facial angiofibromas are most commonly located on the face and have the potential to cause disfigurement. Facial disfigurement negatively affects the quality of life of patients and their families, often leading to negative psychosocial outcomes. Nowadays there are no treatment guidelines for facial angiofibromas but due to the progressive nature of facial angiofibromas a safe technique offering good results is needed. OBJECTIVE AND RESULTS: We report the case of a 40-year-old female affected by tuberous sclerosis, whose facial angiofibromas were satisfactorily treated by rapamycin 0.05% ointment, and a combined laser therapy.
