RESUMO

BACKGROUND: Cellular angiofibroma is a rare benign mesenchymal tumor that mostly occurs in the genital area. Its occurrence outside this region, particularly in the pelvis, is extremely rare. To our knowledge, this study reports the first case of cellular angiofibroma occurring in the pelvic cavity, except for one case reported in the retroperitoneum. CASE PRESENTATION: A 25-year-old female patient with chronic, intermittent, dull pain in the lower abdomen that lasted for several months was referred to our clinic. Imaging studies revealed a tumor in the pelvic cavity anterior to the bladder. The radiographic characteristics of this tumor indicated a hypervascular nature, suggesting the possibility of a pheochromocytoma or a neuroendocrine tumor. The patient underwent surgical excision of the lesion. To date, no recurrence has been observed four months after excision. CONCLUSIONS: Cellular angiofibroma, although rare in the pelvic cavity, should be considered in the differential diagnosis of hypervascular pelvic space-occupying lesions. Immunohistochemical staining can help confirm the diagnosis of this condition. Treatment is generally straightforward, involving local excision of the tumor followed by postoperative monitoring.

RESUMO

RATIONALE: Solitary fibrous tumor (SFT) is a rare mesenchymal tumor, especially the giant one from the abdominal pelvic cavity. We report on a rare case of a giant SFT of the abdominal pelvic cavity to review the existing literature in detail to improve the diagnosis and treatment of SFT. PATIENT CONCERNS: The patient is a 52-year-old female who presented with 2 weeks of abdominal distension. Abdominal magnetic resonance imaging showed a giant mass (>20 cm) in the abdominal pelvic cavity, considered a mesenchymal tumor. She denies a history of tumor disease. DIAGNOSES: A whole abdomen bulge and a mass of about 18 cm × 10 cm on the right side and middle side were found in the physical examination after admission. Abdominal enhanced computed tomography revealed a giant cystic-solid mass located on the middle and right side of the abdominal pelvic cavity, measuring approximately 20.4 cm × 11.7 cm, with multiple cystic changes and necrosis and compression of adjacent organs and tissues, and marked inhomogeneous enhancement. INTERVENTIONS: The patient underwent an open abdominal pelvic cavity giant tumor operation to achieve a radical resection, and did not undergo chemotherapy or radiotherapy. OUTCOMES: The patient underwent open complete resection of a giant abdominal pelvic tumor with no complications and was diagnosed as SFT according to the pathology, immunohistochemistry showed that the tumor tested positive for CD34(+), STAT-6(+), and Ki-67 (10%). Abdominal computed tomography scans were performed 6 months after resection, and no signs of recurrence or metastasis were found. LESSONS: The clinical symptoms and imaging features of giant abdominal pelvic cavity SFT are not typical. Preoperative diagnosis is difficult and has the potential for malignancy. Based on the results of the current study, there is no standard treatment strategy around the world and the therapeutic effect of radiation therapy and chemotherapy is relatively limited. Thus, complete surgical resection and close clinical follow-up are advocated.

RESUMO

BACKGROUND: Neuroblastoma accounts for 15 % of cancer deaths in children. Complete surgical resection is associated with a higher overall survival rate but also a higher morbidity rate. An international group of experts has defined a nomenclature of image-defined risk factors (IDRFs) for the determination of operability and the anticipation of reasonably foreseeable complications of surgery. However, there is no consensus on the optimal imaging modality (CT or MRI) for the assessment of IDRFs. The objective of the present study was to determine the non-inferiority of MRI vs. CT in the preoperative assessment of abdominopelvic neuroblastoma. The secondary objective was to assess the contribution of gadolinium contrast enhancement. METHODS: All children diagnosed with abdominopelvic neuroblastoma and whose preoperative work-up included a contrast-enhanced CT or MRI scan of the abdomen and pelvis between January 2014 and January 2023 were included. To evaluate the IDRFs, all the images were reviewed in three steps: (i) non-contrast MRI scans, (ii) both non-contrast and contrast-enhanced MRI scans, and (iii) contrast-enhanced CT scans. RESULTS: Twenty-five patients were found to be eligible, and fifteen were included. The mean time interval between MRI and preoperative CT was 23 days. In all patients, the identified IDRFs were similar for all three imaging modalities. Fourteen patients underwent full resection of the tumour. The surgical reports were fully consistent with the IDRFs described on CT and/or MRI. CONCLUSION: A high-resolution three-dimensional T2 MRI sequence agreed fully with contrast-enhanced CT for the detection of IDRFs. Contrast-enhanced MRI did not add value. However, surgeons will need time to adapt to this MRI-based approach and learn how to interpret the results with confidence.

RESUMO

Background: The objective of this investigation is to evaluate the superiority of dose-volume parameters relying on magnetic resonance imaging (MRI)-defined active bone marrow (ABM) over those based on total bone marrow (TBM) contoured via CT in the prediction of hematologic toxicity (HT) occurrence among patients with pelvic malignancies undergoing radiotherapy. Methods: The clinical data of 116 patients with pelvic malignancies treated with pelvic radiotherapy were analyzed retrospectively. The ABM areas on T1-weighted MRI were contoured. The statistical significance between TBM and ABM dose-volume measures was assessed through the utilization of either Student's t-test or Wilcoxon signed rank test. Logistic and linear regression models were employed to analyze the correlation between dose-volume parameters (V5-V50) and HT occurrence in pelvic ABM and TBM. Receiver operating characteristic (ROC) curves were used to compare predictors of HT2+. Results: There were significant differences in dosimetric parameters between ABM and TBM. Logistic regression analysis showed that ABM V5, ABM V10, ABM V15, ABM V20, and TBM V5 were significantly associated with the occurrence of HT2+ in pelvic malignancies. Linear regression analysis showed that ABM V5, ABM V10, and ABM V15 were significantly associated with white blood cell (WBC), absolute neutrophil count (ANC), hemoglobin (Hb), and lymphocyte (Lym) nadir. ABM V5, ABM V10, ABM V15, and ABM V30 were predictive of HT2+. Conclusions: More accurate prediction of HT in patients receiving pelvic radiotherapy may be achieved by relying on dose-volume parameters of MRI-based ABM. Further prospective studies are needed to confirm this.

RESUMO

The most common abdominal malignancies diagnosed in the pediatric population include neuroblastoma, Wilms tumor, hepatoblastoma, lymphoma, germ cell tumor, and rhabdomyosarcoma. There are distinctive imaging findings and patterns of spread for each of these tumors that radiologists must know for diagnosis and staging and for monitoring the patient's response to treatment. The multidisciplinary treatment group that includes oncologists, surgeons, and radiation oncologists relies heavily on imaging evaluation to identify the best treatment course and prognostication of imaging findings, such as the image-defined risk factors for neuroblastomas, the PRETreatment EXtent of Disease staging system for hepatoblastoma, and the Ann Arbor staging system for lymphomas. It is imperative for radiologists to be able to correctly indicate the best imaging methods for diagnosis, staging, and restaging of each of these most prevalent tumors to avoid inconclusive or unnecessary examinations. The authors review in a practical manner the most updated key points in diagnosing and staging disease and assessing response to treatment of the most common pediatric abdominal tumors. ©RSNA, 2024 Supplemental material is available for this article.

RESUMO

BACKGROUND: The diagnostic ability of endoscopic ultrasound (EUS) for intestinal infiltration by pelvic masses has aroused considerable interest in many oncological settings. This study aimed to evaluate the effectiveness of EUS in predicting colorectal invasion in patients with pelvic masses and compare its accuracy with that of other imaging methods, namely pelvic MRI and abdominal computed tomography (CT), in predicting intestinal involvement in patients with histologically confirmed colorectal invasion. METHODS: A hundred and eighty-four female patients with histologically confirmed benign or malignant pelvic masses were enrolled in a retrospective-prospective study. All patients underwent EUS, pelvic MRI, and one or more of abdominal CT, transvaginal sonography, and colonoscopy examinations before surgery. The surgical and pathological results were used as the gold standard to evaluate the diagnostic accuracy of EUS for colorectal invasion of pelvic masses. RESULTS: This study included 184 patients who underwent surgery, with the time between EUS and surgery ranging from 1 to 309 (mean, 13.2) days. The diagnostic sensitivity, specificity, positive predictive value, and negative predictive value of EUS for benign and malignant pelvic masses infiltrating the intestine were 83.3, 97.8, 99.1, and 66.2%, respectively. The overall diagnostic accuracy was 87.0%. CONCLUSIONS: EUS is a simple, noninvasive, reliable, and accurate technique for the preoperative diagnosis of pelvic masses infiltrating the intestine. The authors recommend the use of this technology by gynecologists, as well as its incorporation into the preoperative diagnostic process to determine the most suitable surgical method. This would help in avoiding unexpected situations and unnecessary resource wastage during surgery.

RESUMO

OBJECTIVE: Three-dimensional (3D) reconstructed models have been shown to improve visualization in complex female pelvic tumors. Cinematic rendering (CR) is a 3D imaging technique for computed tomography (CT) images, which creates more realistic images with the ability to enhance imaging of anatomical features for diagnosis. This study was set up to compare two types of 3D models and to validate the use of 3D anatomical techniques for the diagnosis of complex female pelvic tumors. METHODS: The preclinical, randomized, two-sequence crossover investigation was performed from December 2022 to January 2023 at First Affiliated Hospital of Chongqing Medical University. Sixteen residents and 10 attending surgeons assessed the cases of 23 patients with two types of 3D model images. The surgeons were randomly assigned to two assessment sequences (CR-3D model group and CT-3D model group). For each case, participants selected one question that probed fundamental questions about the tumor's genesis throughout each assessment period. Following a 4-week washout period, case assessments were transferred to the other image modality. RESULTS: The main result assessment was the accuracy of the answers. The time to answer the questions and the case assessment questionnaire was added as a secondary outcome. The mean scores in the CR-3D models (19.35 ± 1.87) varied significantly from those in the CT-CR group (16.77 ± 1.8) (P < 0.001), and solving the questions in the CT-3D model sequence (41.96 ± 6.31 s) varied significantly from that in the CR-3D model sequence (52.88 ± 5.95 s) (P < 0.001). Subgroup analysis revealed that there were statistically significant variations in the scores of female reproductive tumors, pelvic tumors other than the reproductive system, and retroperitoneal tumors (P = 0.005). Analysis of the assessment questionnaire showed that more surgeons choose CR 3D reconstruction (8.31 ± 0.76 vs 7.15 ± 1.19, P < 0.001). CONCLUSIONS: The results suggest that each 3D reconstruction method has its own advantages. Surgeons feel that CR reconstruction models are a useful technique that can improve their comprehension of complex pelvic tumors, while traditional 3D models have an advantage in terms of speed to diagnosis.

RESUMO

BACKGROUND AND AIMS: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a potentially valuable tool for the diagnosis of pelvic lesions. The aim of this meta­analysis was to evaluate the efficacy and feasibility of EUS-FNA in the diagnosis of pelvic lesions. METHODS: We performed a computerized search of PubMed, EMBASE, Cochrane Library, and Science Citation Index, through March 2023. The main outcome measures examined in the meta-analysis were sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy. RESULTS: We evaluated 22 trials that used surgical pathology or imaging follow-up results as the reference standard. The studies comprised 844 patients. The cumulative sensitivity, specificity, PPV, NPV, and accuracy were 94%, 100%, 100%, 89%, and 96%, respectively. In the subgroup analysis, the prospective studies revealed the cumulative sensitivity, specificity, PPV, NPV, and accuracy were 91%, 100%, 100%, 85%, and 93%, respectively. CONCLUSIONS: In conclusion, we provide evidence that EUS-FNA is a qualitative diagnostic technique with high sensitivity, specificity, PPV, and accuracy. However, its NPV is slightly low, which does not exclude the risk of a missed diagnosis, and more randomized controlled trials or prospective studies are still needed in the future. EUS-FNA is effective and feasible for pelvic space-occupying lesions. This technique has high clinical application value for pelvic lesions.

RESUMO

Abstract Müllerian adenosarcoma is a very rare gynecological disease, comprising 5% of uterine sarcomas. Extragenital localizations are even rarer.We report a very interesting case of a 27-year-old woman complaining of pelvic pain, with a subsequent diagnosis of extragenital Müllerian adenosarcoma. This is the first case reported in the literature with a complete and wide imaging description. Even if rare, Müllerian adenosarcoma should be hypothesized in case of young female patients presenting with suspicious pelvic mass.


Resumo O adenosarcoma Mülleriano é uma doença ginecológica muito rara, compreendendo 5% dos sarcomas uterinos. Localizações extragenitais são ainda mais raras. Relatamos um caso muito interessante de uma mulher de 27 anos queixando-se de dor pélvica com diagnóstico subsequente de adenosarcoma Mülleriano extragenital. Este é o primeiro caso relatado na literatura com uma descrição completa e ampla de imagem. Mesmo que raro, o adenosarcoma Mülleriano deve ser hipotetizado no caso de pacientes jovens do sexo feminino com massa pélvica suspeita.

RESUMO

La actinomicosis es una enfermedad crónica granulomatosa poco común causada por bacterias gram positivas, anaeróbicas, microaerófilas principalmente del género Actynomices. Se presenta el caso de una mujer de 49 años de edad, con cuadro clínico de aproximadamente 4 meses de evolución dado por estreñimiento, asociado a tenesmo rectal durante la defecación y pérdida de peso, portadora de dispositivo intrauterino desde hace 7 años. En el examen físico se encontró la presencia de una masa, de bordes mal definidos, en flanco y fosa iliaca derechos, y en hipogastrio, no dolorosa a la palpación. El ultrasonido abdominal reportó una masa en lóbulo caudado hepático y una estructura de contornos mal definidos en íntimo contacto con techo vesical y fundus uterino. La biopsia de lesión reveló actinomicosis. Se confirma la actinomicosis en una paciente con masa palpable en hipogastrio y dispositivo intrauterino colocado(AU)


Actinomycosis is an uncommon granulomatous chronic disease caused by gram-positive, anaerobic, microaerophilic bacteria, mainly of the genus Actynomices. We present the case of a 49-year-old woman with a clinical condition of approximately 4 months of evolution due to constipation, associated with rectal tenesmus during defecation and weight loss, carrier of an intrauterine device for 7 years. In the physical examination, the presence of a mass was found, with poorly defined edges, flank anda iliac fossa right, and hypogastrium, not painful on palpation. Abdominal ultrasonography reported a mass in the hepatic caudate lobe and a structure of ill-defined contours in intimate contact with the bladder roof and uterine fundus. The lesion biopsy revealed actinomycosis. It was confirmed in a patient with palpable mass in hypogastrium and intrauterine device placed(AU)

RESUMO

ABSTRACT In recent years, medical imaging with hybrid techniques has widely accepted and employed in clinical routine. PET/MRI offers significant advantages, including excellent contrast and resolution and reduced ionizing radiation, as compared to well-established PET/CT. Therefore, PET/MRI is a promising modality for oncologic imaging of some regions, such as brain, head and neck, liver and pelvis. This article set out to analyze clinical conditions that could benefit from PET/MRI imaging based on our caseload. The potential of PET/MRI to become the imaging modality of choice for assessment of neurologic and oncologic conditions associated with soft tissues is highlighted. Clinical aspects of PET/MRI and its application to clinical cases are illustrated with examples extracted from the authors’ preliminary experience.


RESUMO Nos últimos anos, imagens médicas com tecnologias híbridas tornaram-se amplamente aceitas e utilizadas na prática clínica. O PET/RM possui vantagens importantes, incluindo excelentes contrastes e resolução, e menor radiação ionizante, em comparação ao PET/TC. Por isto, é uma modalidade promissora para exames de imagem de pacientes oncológicos, para avaliar o cérebro, cabeça e pescoço, o fígado e a pelve. O objetivo deste artigo foi analisar as situações clínicas que se beneficiariam de exames de PET/RM a partir de uma casuística. Destacamos o potencial desta técnica se tornar o método de imagem de escolha para doenças neurológicas e oncológicas que envolvam partes moles. Os aspectos clínicos de PET/RM e sua aplicação aos casos clínicos são ilustrados com exemplos da experiência inicial dos autores.

RESUMO

Pelvic recurrence after resection of rectal adenocarcinoma is a feared complication and is associated with a worse prognosis and low resectability rates. The differential diagnosis is difficult, as biopsy is seldom performed preoperatively. We report two cases of desmoid pelvic tumor after resection of rectal adenocarcinoma. Therapeutic options and literature review are described.


O aparecimento de tumor pélvico após ressecção de adenocarcinoma de reto é complicação temida e está associado à pior prognóstico e baixos índices de ressecabilidade. O diagnóstico diferencial é difícil, pois o diagnóstico histológico usualmente não é realizado no pré-operatório. São relatados dois casos em que houve o aparecimento de tumor pélvico após a ressecção de adenocarcinoma de reto, com diagnóstico histológico de tumor desmóide. As condutas adotadas e revisão da literatura são descritas.
