ABSTRACT

Massas intracardíacas constituem um desafio diagnóstico, já que os sintomas são comuns a patologias cardiovasculares ou não. Métodos ­ invasivos ou não ­ possibilitam o diagnóstico diferencial e a confirmação histológica, propiciando tratamento adequado. Para melhor compreender a importância da multimodalidade em imagem e a abordagem nos tumores cardíacos , relatamos o caso de um lifoma cardíaco primário, em que a abordagem multidisciplinar permitiu o rápido diagnóstico e seu tratamento, inclusive das intercorrências, com resposta inicial promissora, a despeito da evolução fatal durante a pandemia por SARS-CoV-2.(AU)


Intracardiac masses are a diagnostic challenge since their symptoms can be common to cardiovascular pathologies. Some methods, whether invasive or not, enable differential diagnosis, histological confirmation, and adequate treatment. To better understand the importance of imaging multimodality and the approach to managing cardiac tumors, we investigated a case of a primary cardiac lymphoma in which the multidisciplinary approach allowed rapid diagnosis and treatment, including of intercurrences, with a promising initial response despite fatal progression due to severe acute respiratory syndrome coronavirus 2 infection.

ABSTRACT

Introducción: Los linfomas no Hodgkin tienen su origen generalmente en el sistema linfoide, existe una gran diversidad de ellos, que hace difícil su clasificación y diagnóstico anatomopatológico definitivo. También hay localizaciones extranodales, como en el cerebro, lo que la hace aún más interesante. Objetivo: Presentar un caso con linfoma marginal cerebral, de diagnóstico muy infrecuente. Caso clínico: Paciente femenina de 67 años de edad con antecedentes patológicos personales de hipertensión arterial y epilepsia, que comenzó a sentirse rígida, con movimientos involuntarios generalizados en el cuerpo, hasta perder la conciencia. Al recuperarse se encontraba somnolienta y con cefalea de moderada intensidad. Se diagnostica un linfoma no Hodgkin tipo MALT cerebral; se realiza tratamiento con el que se revierten los síntomas y se controla la enfermedad. Conclusiones: Es necesario un diagnóstico histopatológico oportuno y certero, con la utilización de los estudios inmunohistoquímicos. Esto permite aplicar un tratamiento precoz y el control de la enfermedad(AU)


Introduction: Non-Hodgkin's lymphomas generally have their origin in the lymphoid system, there is a great diversity of them, which makes their classification and definitive pathological diagnosis difficult. There are also extranodal locations, such as in the brain, which makes it even more interesting. Objective: To present a patient with marginal cerebral lymphoma, of a very infrequent diagnosis. Clinical case: A 67-year-old female patient with a personal pathological history of arterial hypertension and epilepsy, who began to feel rigid, with involuntary movements that generalized to the whole body, until she lost consciousness, when she recovered she was drowsy and with headache of moderate intensity. Brain MALT non-Hodgkin lymphoma is diagnosed, treatment is performed to reverse symptoms, and the disease is controlled. Conclusions: A timely and accurate histopathological diagnosis is necessary, with the use of immunohistochemical studies. This allows for early treatment and disease control(AU)

ABSTRACT

Introdução: Tanto o angiossarcoma esplênico quanto o linfoma não Hodgkin (LNH) de células B não só são raros como apresentam desafios diagnósticos. Relato do caso: Paciente do sexo masculino, 45 anos, obeso, sudorese noturna há um ano, e dor abdominal cíclica há dois, com clínica inicial de angiossarcoma, contudo, sob o exame histopatológico e imuno-histoquímico, mostrou tratar-se de LNH de células B com apresentação atípica. A ultrassonografia (US) de abdome total realizada ao início do sintoma de sudorese noturna não teve alterações. Após um ano, a US apresentou massa esplênica. Na ressonância magnética da região abdominal, constatou-se tumoração esplênica expansiva heterogênea no aspecto anterior, suspeita de angiossarcoma esplênico. Após esplenectomia total, pancreatectomia caudal e linfadenectomia retroperitoneal, o exame histopatológico mostrou neoplasia maligna pouco diferenciada extensamente necrótica substituindo o parênquima esplênico. O estudo imuno-histoquímico foi positivo para os marcadores CD20 em diversos focos, para o BCL2 e para o KI67 (em 95% dos núcleos das células neoplásicas). A histopatologia e a imuno-histoquímica foram compatíveis com o diagnóstico de LNH difuso de alto grau, com imunofenótipo B do baço, sem sinal de infiltração de tecidos adjacentes. Após a esplenectomia total e quatro ciclos de quimioterapia, o paciente estava livre do linfoma e sem sintomas. Conclusão: É de suma importância o reconhecimento do diagnóstico correto de neoplasias raras como a relatada. Tanto a clínica quanto os exames de imagem, mesmo que fundamentais, podem ser imprecisos, reiterando a importância dos exames histológico e imuno-histoquímico complementares


Introduction: Both the splenic angiosarcoma and the B-cell non-Hodgkin's lymphoma (NHL) are not only rare but are challenging to diagnose. Case report: Male patient, 45 years old, obese, night sweats for one year, and cyclic abdominal pain for two years, with an initial angiosarcoma clinic, however after immunohistochemistry test, it was revealed a B-cell NHL with atypical presentation. The total abdomen ultrasound (US) performed at the onset of the night sweating symptom showed no alterations. After one year, the US showed a splenic mass. Magnetic resonance imaging of the abdominal region revealed a heterogeneous expansive splenic lesion in the anterior aspect with suspected splenic angiosarcoma. After full splenectomy, caudal pancreatectomy, and retroperitoneal lymphadenectomy, histological analysis showed an area of poorly differentiated necrotic malignancy infiltrated in the splenic parenchyma. Immunohistochemical analysis was positive for CD20 reagents in several foci, BCL2, and for KI67 (in ninety percent of the neoplastic cell nucleus). Histopathology and immunohistochemistry are consistent with high-grade, diffuse, NHL of immunophenotype B in the spleen, with no sign of metastasis to adjacent tissues. After total splenectomy and four rounds of chemotherapy, the patient had remission of the tumor and was asymptomatic. Conclusion: It is extremely important to recognize the relevance of the correct diagnosis of rare neoplasms such as the one reported. Both clinical and imaging tests, although important, can be inaccurate, reiterating the importance of complementary histologic and immunohistochemical tests


Introducción: El angiosarcoma esplénico e el linfoma no Hodgkin (LNH) de células B no solo son raros sino que presentan un reto diagnóstico. Relato del caso: Paciente masculino de 45 años, obeso, con sudoración nocturna durante un año y dolor abdominal cíclico durante dos años, con clínica inicial de angiosarcoma, pero bajo inmunohistoquímica mostró LNH de células B con presentación atípica. En la ecografía de abdomen total realizada al comienzo del síntoma de sudoración nocturna no hubo cambios. Después de un año, la ecografía enseñó una masa esplénica. La resonancia magnética de la región abdominal reveló una lesión esplénica expansiva heterogénea en la cara anterior, sospechosa de angiosarcoma esplénico. Tras la esplenectomía total, la pancreatectomía caudal y la linfadenectomía retroperitoneal, el análisis histológico mostró un área de neoplasia maligna necrótica poco diferenciada infiltrada en el parénquima esplénico. El análisis inmunohistoquímico fue positivo para los reactivos CD20 en varios focos, BCL2 y KI67 en el 95% del núcleo celular, la histología y la inmunohistoquímica son consistentes con LNH difuso de alto grado de inmunofenotipo B en el bazo, sin signos de metástasis. Tras esplenectomía total y cuatro rondas de quimioterapia, el paciente presentó remisión del tumor, así como disminución de síntomas. Conclusión: Es de suma importancia reconocer el diagnóstico de neoplasias raras como la reportada. Tanto las pruebas clínicas como las de imagen, aunque fundamentales, pueden ser inexactas, reiterando la importancia de las pruebas histopatológicas e inmunohistológicas

ABSTRACT

Background: The prognosis of Non-Hodgkin Lymphoma (NHL) depends on the type of lymphoma, the extension of the disease and the response to therapy. Aim: To evaluate the prognostic value of pretreatment and interim PET/CT compared to classic prognosis factors and body composition measurement (sarcopenia, adipopenia) in patients with recently diagnosed NHL. Material and Methods: Patients with recently diagnosed NHL who had staging 18F-FDG PET/CT performed between December 2008 and August 2018 were selected. Age, gender, weight, height, B symptoms, laboratory tests, pathology, staging PET/CT findings (Ann Arbor, number of nodal groups and extranodal sites involved, Bulky, maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis), Computed Tomography findings (psoas muscle mass index, psoas area, psoas density, subcutaneous fat index (all of them at L3 level), and Deauville score (Lugano Criteria) were recorded. The prognostic value of each of these factors was assessed using Cox multivariable regressions. Results: Of 138 NHL studied patients (median 61 y, 15-87 y, 60.4% men), 31 of them died due to the disease. The median follow-up was 39 months (1-115 months). The strongest prognostic factors were: B symptoms (p < 0.01), anemia (p < 0.01), hypoalbuminemia (p: 0.01), sarcopenia (p < 0.01), adipopenia (p < 0.01), number of node groups involved (p < 0.01), MTV (p < 0.01), and a bad response in interim PET/CT (p < 0.01). In a comparative Cox multivariable analysis, interim PET/CT was the independent variable with the highest significance (p < 0.01). Conclusions: Early treatment response assessed by interim PET/CT is the strongest prognostic factor in NHL patients.

ABSTRACT

Resumen Introducción: La evaluación de la respuesta al tratamiento de linfoma se basa en estudios de imagen. Objetivo: Correlacionar la evaluación de la respuesta al tratamiento de linfoma mediante tomografía axial computarizada (TAC) y tomografía por emisión de positrones/tomografía computarizada (PET/TC). Método: Estudio observacional transversal en el que se revisaron expedientes de pacientes con linfoma en vigilancia mediante TAC y PET/TC. Resultados: La población de estudio estuvo constituida por 43 pacientes con edad media de 32.7 ± 22.4 años; 26 (60.5 %) tenían diagnóstico de linfoma de Hodgkin y 17 (9.5 %), de linfoma no Hodgkin. Por TAC se diagnosticaron 34 (79.1 %) con enfermedad y nueve (20.9 %) sin enfermedad. El criterio para evaluar la respuesta fue la experiencia del médico imagenólogo en 39 (90.7 %) y RECIST 1.1 en cuatro (9.3 %). Por PET/TC con 18-FDG se diagnosticó falta de respuesta al tratamiento o respuesta parcial-recurrencia en 32 pacientes (74.4 %) y con respuesta al tratamiento en 11 (25.6 %); con los criterios PERCIST en 13 (30.2 %) y con los de Deuaville en 30 (69.8 %). Al comparar el diagnóstico por TAC contra PET/TC, de 11 pacientes con respuesta total, tres tuvieron diagnóstico tomográfico similar. De los 34 pacientes con datos de enfermedad diagnosticados por tomografía, 26 tuvieron resultados similares por PET/TC con 18-FDG (p = 0.54). Conclusión: El valor de la respuesta al tratamiento por TAC en linfoma no concuerda con el obtenido mediante PET/TC con 18-FDG.


Abstract Introduction: The assessment of lymphoma response to treatment is based on imaging studies. Objective: To correlate the assessment of lymphoma treatment response by computed tomography (CT) and by positron emission tomography/computed tomography (PET/CT). Method: Cross-sectional, observational study, where records of patients with lymphoma under surveillance by CT and PET/CT were reviewed. Results: The study population consisted of 43 patients with a mean age of 32.7 ± 22.4 years; 26 (60.5 %) had a diagnosis of Hodgkin’s lymphoma and 17 (9.5 %) had non-Hodgkin lymphoma. By CT, 34 (79.1 %) were diagnosed with disease and nine (20.9 %) without disease. The criteria used to assess the response was radiologist experience in 39 (90.7 %) and RECIST 1.1 criteria in four (9.3 %). The diagnosis by 18-FDG PET/CT was no response to treatment or partial response-recurrence in 32 (74.4 %) and response to treatment in 11 (25.6 %); with PERCIST criteria in 13 (30.2 %) and Deuaville criteria in 30 (69.8 %). When the diagnosis by CT versus 18-FDG PET/CT was compared, out of 11 patients with complete response on PET/CT, three had a similar CT diagnosis. Of the 34 patients with data consistent disease diagnosed by CT, 26 had similar results by 18-FDG PET/CT (p = 0.54). Conclusion: The value of lymphoma treatment response on CT does not agree with that obtained by 18-FDG PET/CT.

ABSTRACT

Se presenta el caso de una paciente de 79 años que desde hace 3 meses presenta marcada sudoración nocturna, dolor abdominal en zona de hipocondrio y flanco izquierdo y ligera pérdida de peso. Al examen físico se observa palidez de piel y mucosas, esplenomegalia que rebasa 7 cm el reborde costal izquierdo, superficie lisa, superficie regular. El resto del examen físico fue normal. Se realizan múltiples investigaciones básicas sin poderse identificar el diagnostico. Por la presencia de gran esplenomegalia y la pancitopenia se decide realizar esplenectomía confirmándose un linfoma no Hogkin folicular primario del bazo(AU)


We present the case of a 79-year-old patient who had marked night sweats, abdominal pain in the hypochondrium area and left flank and slight weight loss for 3 months. Physical examination showed pale skin and mucous membranes, splenomegaly that exceeds the left costal margin by 7 cm, smooth surface, and regular surface. The rest of the physical examination was normal. Multiple basic studies were conducted out but the diagnosis was not identified. Due to the presence of great splenomegaly and pancytopenia, it was decided to perform splenectomy, confirming a follicular non-Hodgkin primary splenic lymphoma(AU)

ABSTRACT

Summary Early diagnosis and staging of non-Hodgkin lymphoma (NHL) is essential for therapeutic strategy decision. Positron emission tomography/computed tomography (PET/CT) with fluordeoxyglucose (FDG), a glucose analogue, labeled with fluor-18 (18F-FDG) has been used to evaluate staging, therapy response and prognosis in NHL patients. However, in some cases, 18F-FDG has shown false-positive uptake due to inflammatory reaction after chemo and/or radiation therapy. In this case report, we present a NHL patient evaluated with 18F-FDG and 18F-choline PET/CT scan imaging pre- and post-therapy. 18F-FDG and 18F-choline PET/CT were performed for the purpose of tumor staging and have shown intense uptake in infiltrative tissue as well as in the lymph node, but with some mismatching in the tumor. Post-treatment 18F-FDG and 18F-choline PET/ CT scans revealed no signs of radiotracer uptake, suggesting complete remission of the tumor. 18F-choline may be a complimentary tool for staging and assessment of therapeutic response in non-Hodgkin lymphoma, while non-18F-FDG tracer can be used for targeted therapy and patient management.

ABSTRACT

El linfoma no Hodgkin primario de la glándula suprarrenal es una patología muy poco común. Su diagnóstico inicial es difícil siendo este histológico. El linfoma B difuso de células grandes es el tipo histológico más frecuente. Se presenta el caso mujer de 62 años a la que se le realiza tomografía axial computarizada abdominal que muestra una masa de 18 cms dependiente de la glándula suprarrenal y con características de carcinoma. Se realiza exéresis de la tumoración, siendo la anatomía patológica linfoma difuso de célula grande B. Este tipo de linfoma tiene mal pronóstico describiéndose supervivencias medias en torno a los 13 meses. No existe un régimen terapéutico bien definido; aunque el tratamiento más aceptado es el esquema R-CHOP. El papel de la radioterapia y de la exéresis tumoral no está claramente establecido. El linfoma suprarrenal primario debe tenerse en cuenta en el diagnóstico diferencial de pacientes que presentan una masa suprarrenal. Ante la sospecha de esta patología es preferible realizar una biopsia con aguja guiada por prueba de imagen para evitar una intervención quirúrgica innecesaria(AU)


Primary non- Hodgkin`s lymphoma of the adrenal gland is very rare. Its initial diagnosis is difficult and needs to be histological. Diffuse large B- cell lymphoma is the most common histological type. This is the report of a 62 years old woman, who was performed abdominal tomography to disclose a 18 cm tumor in the adrenal gland with carcinoma characteristics. The tumor was removed and the final pathologic diagnosis was diffuse large B-cell lymphoma. This type of lymphoma has poor prognosis since the average survival rates are roughly 13 months. There is no well-defined therapeutic regimen, although the most widely accepted treatment is R-CHOP scheme. The roles of radiotherapy and tumor resection are not clearly established. Primary adrenal lymphoma should be considered in the differential diagnosis of patients presenting with an adrenal mass. When this condition is suspected, then it is advisable to perform a imaging-guided needle biopsy to avoid unnecessary surgery(AU)

ABSTRACT

A DOENÇA: Os linfomas são canceres do sistema linfático, que se caracterizam pela proliferação anormal das células do tecido linfoide (gânglios linfáticos, baco e outros locais, com menor frequência, como estomago, orofaringe, tireoide, pulmão). Compreendem dois tipos principais: (1) Linfoma (ou Doença) de Hodgkin (LH), e (2) Linfoma não-Hodgkin (LNH), que inclui mais de 25 subtipos histológicos diferentes. Essas duas doenças apresentam algumas características clinicas semelhantes, mas divergem na célula de origem, forma de apresentação, modos de tratamento e nos resultados da terapia. Diferenciação entre os dois grupos de linfoma envolve avaliação de características morfológicas (por exemplo, a presença de células de Reed-Sternberg, que apenas são vistas no LH), imunofenotipicas (p.ex., expressão de antígenos celulares de superfície) e imuno-histoquimicas. O tratamento ­ bem como a resposta a terapia e sobrevida ­ também diferem entre eles. Ambos os tipos apresentam um acometimento muito grande de pacientes em idade produtiva (adultos jovens), ocasionando diminuição de produtividade na idade mais ativa e grande número de anos de vida perdidos durante a doença nessa faixa etária. A TECNOLOGIA: A PET (do inglês Positron Emission Tomography) é uma técnica de diagnóstico por imagens do campo da medicina nuclear desenvolvida no início dos anos 70, logo após a tomografia computadorizada. Ela utiliza traçadores radioativos e o princípio da detecção coincidente para medir processos bioquímicos dentro dos tecidos. Diferentemente de outras tecnologias de imagem voltadas predominantemente para definições anatômicas de doença ­ como os raios-X, a tomografia computadorizada (TC) e a imagem por ressonância magnética (MRI) ­ a PET avalia a perfusão e a atividade metabólica tissulares, podendo ser utilizada de forma complementar ou mesmo substituta a estas modalidades. Porque as mudanças na fisiologia tumoral precedem as alterações anatômicas e porque a PET fornece imagens da função e da bioquímica corporais, a tecnologia é capaz de demonstrar as alterações bioquímicas mesmo onde não existe (ainda) uma anormalidade estrutural evidente, permitindo o diagnóstico mais precoce. A tecnologia utiliza derivados de compostos biologicamente ativos ou fármacos, marcados com emissores de pósitrons e que são processados internamente de uma maneira virtualmente idêntica às suas contrapartidas não-radioativas, fornecendo o mecanismo para registrar a atividade metabólica in vivo. A distribuição desses compostos pode ser medida com um tomógrafo PET, que produz imagens e índices quantitativos dos tecidos e órgãos corporais. ANÁLISE DA EVIDÊNCIA: O PTC tem por foco o uso da Tomografia por Emissão de Pósitrons (PET), uma tecnologia da área de medicina nuclear, no diagnostico, estadiamento e re-estadiamento dos linfomas malignos. Embora pareça ser uma ferramenta diagnostica útil no linfoma, não existe consenso sobre o lugar da PET no manuseio da doença, ela não se encontra ainda coberta pela tabela de reembolso do SUS ou no rol de procedimentos da ANS, e as pressões para essa incorporação vem se intensificando. O trabalho buscou avaliar as evidências disponíveis quanto a sua acurácia em três indicações clinicas: estadiamento de linfomas Hodgkin (LH) e não-Hodgkin (LNH) a época do diagnostico; avaliação da resposta ao tratamento, e diagnostico de lesões residuais pos-terapia. Foram ainda buscadas evidencias acerca da sua influencia nas decisões de manuseio clinico-terapêutico e seu impacto nos desfechos em saúde. CONSIDERAÇÕES FINAIS: Todos os estudos demonstraram relação de custo-efetividade aceitável para a utilização de FDG-PET em pacientes com linfoma. O programa de diagnóstico inicial e após a 1ª linha de quimioterapia - com a PET-CT ­ demonstrou-se mais custo-efetiva, pois diminuiu custos e forneceu maior resolutividade. Os resultados da PET-CT demonstraram 8,7% e 9,8% maior acurácia no estadiamento e na avaliação de resposta do que métodos convencionais de imagem, e, assim, melhorou a condução de 10,25% a 40% dos casos. Em comparação com a estratégia convencional de diagnósticos, custos e ressarcimentos da estratégia com a PET-CT apresentaram vantagens econômicas que igualmente a favorecem tanto no estadiamento inicial e como ao término do tratamento. DELIBERAÇÃO FINAL: Os membros da CONITEC presentes na 21ª reunião do plenário realizada nos dias 04 e 05 de dezembro de 2013 deliberaram, por unanimidade, por unanimidade recomendar a incorporação do PET-CT para o estadiamento e avaliação da resposta ao tratamento do linfoma de Hodgkin e linfoma não Hodgkin na Tabela de Procedimentos, Medicamentos, Órteses, Próteses e Materiais Especiais do Sistema Único de Saúde, conforme critérios estabelecidos pelo Ministério da Saúde. DECISÃO: PORTARIA Nº 9, de 22 de abril de 2014 - Torna pública a decisão de incorporar o PET-CT no estadiamento e avaliação da resposta ao tratamento do linfoma de Hodgkin e linfoma não Hodgkin no Sistema Único de Saúde - SUS.

ABSTRACT

A 40-year-old male presented with clinical and radiological manifestations of right lung atelectasis and post-obstructive pneumonia. Flexible bronchoscopy revealed gross narrowing of the right upper lobe bronchus and a smooth, white endobronchial mass completely occluding the right lower lobe bronchus. Endobronchial biopsy from the mass lesion yielded low grade B-cell non-Hodgkin’s lymphoma. This is one of the rarest presentation of non-Hodgkin’s lymphoma.

ABSTRACT

Diffuse bilateral infiltration of the kidneys by lymphoma is probably the rarest cause of renal insufficiency. Moreover, acute renal failure as the initial manifestation of the lymphoma is reported only in a few cases. A 44-year-old man complaining of bilateral flank pain and weakness for 2 months was admitted with acute renal failure. Ultraonography revealed hyperechoic bilaterally enlarged kidneys and an enlarged spleen. Fat pad aspiration was negative for amyloidosis and serum protein electrophoresis was normal. Needle biopsy of the kidney and pathologic examination showed diffuse infiltration of the interstitium with lymphocytes and atypical cells. Bone marrow aspiration and biopsy were negative for malignant cells. Open kidney biopsy was performed and infiltrated cells positive for CD20 and negative for CD3 markers were observed based upon which diagnosis of diffuse large B-cell type non-Hodgkin lymphoma was made

ABSTRACT

Tc-99m MIBI has recently been used in the functional imaging of various tumors. This prospective study was performed to evaluate the role of Tc-99m MIBI imaging at the time of the initial staging, assessment of treatment response, follow-up studies and survaillance in Hodgkin's and non-Hodgkin's Iymphoma. 25 patients [14 with Hodgkin's and 11 with non-Hodgkin's Iymphoma] underwent 32 studies. The patient's age range wa 19-73 years, with a mean age of 41.7 years. All patients underwent whole body planar imaging following intravenous injection of 20-25 mCi Tc-99m MIBI. Comparative imaging with 3 mCi Tl-201 and 10 mCi Ga-67 injection was done. Clinical, radiographic and biopsy correlation was obtained in all cases
