Aspectos clínico-imagenológicos de pacientes diagnosticados con tuberculosis extrapulmonar, La Habana 2016-2019 / Clinical and imaging aspects of the patients diagnosed with extrapulmonary tuberculosis, Havana 2016-2019

RESUMEN Introducción: La tuberculosis extrapulmonar muestra una complejidad diagnóstica que influye sobre la morbilidad y mortalidad. Objetivo: Caracterizar desde una perspectiva clínico-imagenológica a los pacientes diagnosticados con tuberculosis extrapulmonar, en el Hospital Neumológico Benéfico Jurídico de La Habana, en el período 2016-2019. Método: Se realizó un estudio descriptivo, retrospectivo y transversal en 34 pacientes con diagnóstico de tuberculosis extrapulmonar. Las variables medidas fueron: edad, sexo, factores de riesgo para padecer la enfermedad, síntomas y signos clínicos, hallazgos radiológicos, métodos diagnósticos utilizados y su localización. Resultados: Predominaron pacientes del sexo masculino con edad entre 26 a 35 años (29,4 %). El 73,5 % de los pacientes presentó factores de riesgos para esta enfermedad, los más frecuentes fueron: ser contactos de pacientes con tuberculosis (29,4 %), los exreclusos (17,6 %) y los alcohólicos (14,7 %). El 58,8 % presentó fiebre y síntomas o signos generales como anorexia (44,1 %), pérdida de peso (41,2 %) y astenia (38,2 %). El hallazgo radiológico más común fue el derrame pleural (47 %) y la forma extrapulmonar más frecuente dada por 15 casos (44,1 %) fue la pleuritis tuberculosa. El método clínico-radiológico posibilitó el diagnóstico en el 50 % de los pacientes. Conclusiones: Las manifestaciones clínicas más evidentes fueron la fiebre, la pérdida de peso y la astenia. El método diagnóstico clínico-radiológico es el más utilizado y el hallazgo radiológico más reportado es el derrame pleural. La localización pleural es la forma extrapulmonar más frecuente.

ABSTRACT Introduction: Extrapulmonary tuberculosis shows a complexity that can influence in its morbidity and mortality rates. Objective: To characterize the patients with extrapulmonary tuberculosis from a clinical-imaging perspective in the Hospital Neumológico Benéfico Jurídico in Havana in the period 2016-2019. Method: A descriptive, retrospective and cross-sectional study was carried out in 34 patients with the diagnosis of extrapulmonary tuberculosis. The variables taken into account were: age, gender, risk factors for the disease, symptoms and clinical signs, radiological findings, diagnosis methods used, and location. Results: Male patients with ages ranging between 26 to 35 years predominated in the study (29.4%). 73.5% of the patients presented risk factors of the disease, being most common: contact of previous tuberculosis patients (29.4%), ex-inmates (17.6%) and alcoholics (14.7%). 58.8% of the patients presented fever and general symptoms like anorexia (44.1%), weight loss (41.2%) and asthenia (38.2%). The most common radiological finding was pleural effusion (47%), and the most frequent extrapulomary form of the disease was tuberculous pleurisy (15 cases representing a 44.1%). The clinical-radiological method made diagnose possible in 50% of the patients. Conclusions: The most common clinical manifestations were fever, weight loss and asthenia. The clinical-radiological method is the most frequently used, and the most frequent radiological finding was the pleural effusion. Pleural location was the most common extrapulmonary form of tuberculosis.

Tuberculosis pleural en paciente pediátrico: reporte de un caso y revisión de la literatura / Pleural tuberculosis in a pediatric patient: case report and review

Tuberculosis (TB) is a common cause of pleural effusion in young people from endemic areas. Among the forms of extrapulmonary TB in people with immunodeficiencies, the most frequent localization is the pleura. The use of immunological and molecular biology tests for the diagnosis of TB in pleural fluid and other locations with high sensitivity and specificity is highlighted. We present a clinical case with the objective of giving an overview of the treatment of the patient with suspected pleural tuberculosis

La Tuberculosis (TB) es una causa común de derrame pleural en jóvenes en zonas endémicas. Dentro de las formas de TB extrapulmonar en personas que cursan con inmunodeficiencias, la localización más frecuente es la TB pleural. Se destaca el uso de las pruebas inmunológicas y de biología molecular para el diagnóstico de TB en líquido pleural y de otras localizaciones con una elevada sensibilidad y especificidad. Se presenta un caso clínico con el objetivo de describir una visión general del abordaje del paciente con sospecha de tuberculosis pleural

Diagnostic utility of sonar guided biopsy in tuberculous effusion

Tuberculous pleural effusion remains the commonest cause of exuda tive effusions in areas with a high prevalence of tuberculosis and histological examination of pleural tissue is the gold standard for its diagnosis. This study was to assess the diagnostic utility of sonar guided biopsy in tuberculous pleural effusion. 50 patients [34 men] of mean +/- SD age 38.7 +/- 16.7 years with pleural effusions and a clinical suspicion of tuberculosis were enrolled in the study. Transthoracic ultrasound was performed on all patients, who were then randomly assigned to undergo 4 Abrams needle biopsies followed by 4 Tru-Cut needle biopsies or vice versa. Pleural tuberculosis was diagnosed in 31 patients, alternative diagnoses were established in 16 patients and 3 remained undiagnosed. Pleural biopsy specimens obtained with Abrams needles contained pleural tissue in 29 patients [92.0%] and were diagnostic for tuberculosis in 26 patients [sensitivity 82%], whereas Tru-Cut needle biopsy specimens only contained pleural tissue in 21 patients [78%] and were diagnostic in 21 patients [sensitivity 64%] Ultrasound-assisted pleural biopsies performed with an Abrams needle are more likely to contain pleural tissue and have a significantly higher diagnostic sensitivity for pleural tuberculosis

Pleural tuberculosis masquerading as metastatic malignancy

Tuberculosis involvement of the pleura usually presents as pleural effusion, empyema or pleural thickening. In this communication we report a case of unilateral pleural tuberculosis presenting as multiple nodular masses without effusion, which raised the possibility of metastatic malignancy. Histopathology of the nodules confirmed the diagnosis of tuberculosis; and with standard antituberculosis therapy they disappeared and the patient's symptoms improved
