Hepatic Tuberculosis Granuloma Mimicking Hilar Cholangiocarcinoma Confirmed by Endoscopic Ultrasound-Guided Fine-Needle Aspiration / 대한내과학회지

Hepatic tuberculosis is usually associated with active pulmonary or miliary tuberculosis. The occurrence of an isolated hepatic mass-forming tuberculosis with no evidence of tuberculosis elsewhere is rare. We report a case of a 31-year-old male with a solitary hepatic granuloma mimicking a mass-forming intrahepatic cholangiocarcinoma. Ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography of the abdomen showed a malignant tumor-like lesion. We then conducted endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) for confirmation of the hepatic hilar mass, which was found to be a hepatic tuberculosis granuloma as the final diagnosis.

Primary Hepatosplenic Tuberculosis in an Immunocompetent Adult and Domestic Literature Review

Hepatic or splenic involvement of tuberculosis without other disseminated lesions is a very uncommon form of extrapulmonary tuberculosis, especially in an immunocompetent adult. We report a case of a 25 year-old-man who developed primary hepatosplenic tuberculosis not associated with the lung or other distant organs. He was initially diagnosed with esophageal candidiasis in local clinic. A computed tomographic scan of the abdomen showed hepatosplenomegaly and multiple microabscesses in the spleen. Our initial diagnosis, based on the clinical feature and radiologic findings, was hepatosplenic candidiasis. However, histopathology of the liver specimens revealed chronic granuloma with central caseous necrosis, strongly suggestive of tuberculosis. Although rare, splenic tuberculosis should be considered in the differential diagnosis of splenic abscess, especially in countries where tuberculosis is endemic.

A Case of Multi-Organ Macronodular Tuberculosis / 결핵및호흡기질환

A 37 year old female presented with epigastric pain and weight loss over a period of 3 months. Her abdominal CT finding showed a 4.5 cm size hepatic mass and 4.3 cm size pancreatic head mass with multiple macronodules in the liver. At the same time, her chest CT revealed a 5 cm size necrotic mass in the left lower lobe of the lung with multiple bilateral pulmonary nodules. We diagnosed these lesions as tuberculosis through multiple biopsies. She was treated with anti-tuberculous medication. After taking the medications, her symptoms were improved. Twelve months later, imaging studies indicated an improvement in the patient's health. Here we report a case report of multi-organ macronodular tuberculosis in lung, liver and pancreas.

Imágenes en tuberculosis abdominal / Imaging in tuberculosis abdominal

En este artículo se discuten e ilustran las características por imagen de la afectación abdominal por tuberculosis. Se presenta un grupo de pacientes evaluados a través de diferentes modalidades diagnósticas con síntomas abdominales y hallazgos imaginológicos sugestivos de infección granulomatosa. Este diagnóstico fue confirmado posteriormente en la evolución clínica y con estudio histológico. Se incluyen casos de afectación en diferentes órganos abdominales, como sistema linfático, peritoneo, órganos pélvicos, hígado, bazo, riñones y uréteres.

In this article we illustrate and discuss imaging features resulting from Tuberculosis abdominal affectation. We present patients evaluated with several imaging modalities who had abdominal symptoms and findings suggestives of granoulomatous disease. Diagnosiswas confirm including hystopatology and clinica outgoing. Cases involved presented many affected organs such as lymphatic system, peritoneum, liver, spleen, pancreas, kidneys, ureters, adrenal glands and pelvic organs.

Low mechanical index contrast-enhanced sonographic findings of hepatic tuberculosis / 中华超声影像学杂志

Objective To investigate the appearance and characteristics of hepatic tuberculosis lesions on low mechanical index contrast-enhanced ultrasound. Methods Eight patients with hepatic tuberculosis lesions were studied with conventional ultrasound and contrast-enhanced ultrasound. Lesions,distribution.size,echogenieity,blood flow,enhancement phase,enhancement patterns and intensity were studied. ResuIts Fifteen lesions were found in eight patients. On conventional ultrasound,mean size of the lesions was(21.7±10.7)mm×(30.3±22.4)mm,and 66.7%(10/15)lesions located under liver capdule,and 33.3%(5/15)were in hepatic parenchyma.All lesions were hypoechoic except the largest one (50 mm x 102 mm)which demonstrated heterogeneous.Doppler signals were not demonstrated in all 15 lesions.After administration of SonoVue,satisfied image data were obtained in 13 lesions for aterial phase,and 15 lesions for portal venous phase and parenchyma phase.84.6%(11/13)of the lesions demonstrated hyperenhancing on aterial phase,mean enhancing start time was(8.6±1.6)s,ranging from 5 s to 10 s.and mean enhancing end time was(25.6±2.8)s,ranging from 20 s to 29 s. Of 13 lesions,6 lesions demonstrated circle periphery hyper-enchanCement,5 lesions demonstrated whole hyper-enchancement,and 2 lesions appeared hypoenhancement on arterial phase. All lesions demonstrated either hypoenhancing or non-enhancement on portal venous phase and parenchyma phase. Conclusions Low mechanical index contrast-enhanced ultrasound can reveal the blood flow status of hepatic tuberculous lesions and will facilitate the diagnosis of hepatic tuberculosis.

A case of asymptomatic primary liver tuberculosis proven by percutaneous liver biopsy / 北京大学学报(医学版)

SUMMARY The patient, an 18-year-old girl, was found to have strong positive purified protein derivative of tuberculin (PPD) test and calcified focus in her liver 2 years ago. She denied fever, cough, sputum, weight loss, night sweats, fatigue, and anorexia. After admission, physical examination, laboratory tests, CXR, abdominal CT, colonoscopy and gynecological examination were all normal except for the liver lesions. Percutaneous needle biopsy was performed under sonographic guidance and pathological examination showed caseous granuloma. She was diagnosed as primary liver tuberculosis and the lesions decreased after 2 months’ therapy of isoniazid, rifampicin and ethambutol. Primary liver tuberculosis could be asymptomatic and manifestated as calcified focus; percutaneous needle biopsy and pathological examination is helpful for the diagnosis. The asymptomatic liver lesions are still an indication for anti-tuberculosis therapy.

A case of primary solitary tuberculoma of the liver treated with antituberculosis chemotherapy and surgical excision / 대한내과학회지

The solitary form of primary hepatic tuberculosis is a rare disease. We report an unusual case of primary solitary hepatic tuberculosis treated with surgical resection and second-line antituberculosis chemotherapy due to the recurrence after first-line antituberculosis chemotherapy alone. A 36-year-old man was presented with right upper abdominal discomfort, chills and weight loss for 2 months. Computerized tomography demonstrated the solitary space occupying lesion on the left lobe of liver suggesting a malignant disease. The open biopsy revealed chronic granulomatous inflammation with multinucleated giant cells and caseous necrosis. The patient was treated with antituberculosis chemotherapy for nine months and eighteen months respectively with the interval of eighteen months. But the hepatic lesion had become larger and symptoms were aggravated after the discontinuation of therapy. He underwent surgical excision of the lesioin. With second-line antituberculosis chemotherapy, the symptoms improved in postoperative days. Twenty four months later, no evidence of recurrence was noted in symptoms, laboratory findings and imaging studies.

Surgical therapy for hepatic tuberculosis: a report of 8 cases / 中国普通外科杂志

Objective To study the clinical features and operative methods for patients with hepatic tuberculosis.Methods The clinical features、diagnosis、operative methods and the location of tuberculosis focus in the liver were analysed in 8 patients. Results Difinite preoperative diagnosis could be reached in none of the 8 patients. Surgical procedure included focus remove (5 cases) and deroof plus drainage (3 cases). The diagnosis of hepatic tuberculosis was proved by pathological examination. [WT5”HZ]Conclusions Surgical resection plus anti tuberculosis drugs are the mainstay for the treatment of patients with hepatic tuberculosis.
