  2. Pitfalls in imaging of female pelvic masses

    Horta, Mariana; Cunha, Teresa Margarida
    Purpose of Review The purpose of this review is to highlight potential magnetic resonance (MR) imaging pitfalls that may mask and simulate ovarian cancer. Recent Findings MR imaging is the standard method for evaluating female pelvic masses of indeterminate origin, especially sonographically indeterminate adnexal masses. To define the correct origin and nature of a pelvic mass has an enormous clinical impact, namely in females of child-bearing age. This is particularly true in adnexal lesions. Ovarian cancer usually requires a cytoreductive surgery in a specialized oncological centre. In contrast, a benign ovarian lesion may be treated by simple resection in a general hospital. To help preventing diagnostic errors and in order to guide appropriate...

  4. Mature cystic teratoma with high proportion of solid thyroid tissue: a controversial case with unusual imaging findings

    Gil, Rui; Cunha, Teresa Margarida; Rolim, Inês
    We describe a case of a mature cystic teratoma of the ovary with high proportion of solid thyroid tissue (< 50% of the entire tumor) in a childbearing woman. The patient presented with non-specific abdominal bloating. Pelvic ultrasound and magnetic resonance imaging revealed a complex cystic-solid tumor confined to the left ovary with an anterior fatcontaining locus compatible with mature cystic teratoma and a posterior predominantly solid component with low signal intensity on T2-weighted images that was histopatologically diagnosed as benign thyroid tissue. Thyroglobulin levels were in normal range. Although thyroid tissue is present in up to 20% of mature cystic teratomas, with exception of struma ovarii, it is not...

  6. Adnexal masses: benign ovarian lesions and characterization - benign ovarian masses

    Schlattau, Alexander; Cunha, Teresa Margarida; Forstner, Rosemarie
    Incidental adnexal masses are commonly identified in radiologists’ daily practice. Most of them are benign ovarian lesions of no concern. However, sometimes defining the origin of a pelvic mass may be challenging, especially on ultrasound alone. Moreover, ultrasound not always allows the distinction between a benign and a malignant adnexal tumor. Most of sonographically indeterminate adnexal masses turn out to be common benign entities that can be readily diagnosed by magnetic resonance imaging. The clinical impact of predicting the likelihood of malignancy is crucial for proper patient management. The first part of this chapter will cover the technical magnetic resonance imaging aspects of ovarian lesions characterization as well as the imaging features that allow the radiologist to correctly...

  8. Bernardino António Gomes: ilustre médico iluminista nascido em Paredes de Coura

    Subtil, Carlos
    Para além da apresentação de dados bio e bibliográficos do Doutor Bernardino António Gomes, com esta publicação pretende-se traçar um quadro geral da saúde pública e da medicina coeva de uma das figuras médicas mais relevantes dos séculos XVIII e XIX, a nível nacional e europeu. Ao evidenciar o carácter inovador e visionário deste homem de ciência, destaca-se, ainda, o seu papel e obra como médico da Armada, médico de saúde pública e dermatologista, enquanto membro das mais importantes instituições de produção do conhecimento científico e da governação em saúde, tais como a Academia Real das Ciências, a Junta de...

  9. MR and CT techniques

    Dias, João Lopes; Cunha, Teresa Margarida
    Magnetic resonance imaging (MRI) and computed tomography (CT) are routinely used in female pelvis imaging. MRI is primarily useful for locoregional characterization of benign and malignant diseases. CT is less accurate in locoregional evaluation, but remains useful in the follow-up of treated gynecological malignancies, as well as in the setting of emergency and in the guidance of biopsies. Although transabdominal and transvaginal ultrasonography (US) is not under the scope of this chapter, it remains the first-line imaging method for most gynecological conditions.

  10. European society of urogenital radiology (ESUR) guidelines: MR imaging of pelvic endometriosis

    Bazot, M.; Bharwani, N.; Huchon, C.; Kinkel, K.; Cunha, T. M.; Guerra, A.; Manganaro, L.; Buñesch, L.; Kido, A.; Togashi, K.; Thomassin-Naggara, I.; Rockall, A. G.
    Endometriosis is a common gynaecological condition of unknown aetiology that primarily affects women of reproductive age. The accepted first-line imaging modality is pelvic ultrasound. However, magnetic resonance imaging (MRI) is increasingly performed as an additional investigation in complex cases and for surgical planning. There is currently no international consensus regarding patient preparation, MRI protocols or reporting criteria. Our aim was to develop clinical guidelines for MRI evaluation of pelvic endometriosis based on literature evidence and consensus expert opinion. This work was performed by a group of radiologists from the European Society of Urogenital Radiology (ESUR), experts in gynaecological imaging and a gynaecologist expert in methodology. The group discussed indications for MRI,...

  11. Transperineal aggressive angiomyxoma

    Pereira, Pedro; Abreu, Elisa Melo; Cunha, Teresa Margarida; Rolim, Inês
    A 45-year-old woman with a history of total hysterectomy with adnexal preservation for uterine leiomyomas presented to our hospital with a right gluteal palpable mass, which she first noticed 6 months before and had progressively enlarged since then. Radiological studies revealed a 14 cm lesion with translevator growth that displaced rather than invaded adjacent structures, with a peculiar whorled pattern on T2-weighted MRI, which enhanced following gadolinium administration. CT-guided biopsy was performed, and in conjunction with imaging features the diagnosis of an aggressive angiomyxoma was assumed and confirmed following surgical excision.

  12. ESUR recommendations for MR imaging of the sonographically indeterminate adnexal mass: an update

    Forstner, Rosemarie; Thomassin-Naggara, Isabelle; Cunha, Teresa Margarida; Kinkel, Karen; Masselli, Gabriele; Huch, Rahel Kubik; Spencer, John; Rockall, Andrea
    An update of the 2010 published ESUR recommendations of MRI of the sonographically indeterminate adnexal mass integrating functional techniques is provided. An algorithmic approach using sagittal T2 and a set of transaxial T1 and T2WI allows categorization of adnexal masses in one of the following three types according to its predominant signal characteristics. T1 'bright' masses due to fat or blood content can be simply and effectively determined using a combination of T1W, T2W and FST1W imaging. When there is concern for a solid component within such a mass, it requires additional assessment as for a complex cystic or cystic-solid mass. For low T2 solid adnexal masses, DWI is now...
