Clinical characteristics for distinguishing between acute cardiogenic pulmonary edema and community-acquired pneumonia in elderly patients: a prospective observational study.

Heart failure and pneumonia are highly prevalent in elderly patients. We conducted a study to evaluate the differences in the patterns of symptoms, laboratory findings, and computed tomography (CT) results in elderly patients with acute cardiogenic pulmonary edema (ACPE) and community-acquired pneumonia (CAP). From January 1, 2015 to December 31, 2017, we studied 140 patients aged >75 years who were diagnosed with ACPE and CAP. Symptoms, laboratory findings, mean ostial pulmonary vein (PV) diameter and patterns on CT images were assessed. The primary measures of diagnostic accuracy were assessed using the positive likelihood ratio (LR+). The cutoff value of ostial PVs for differentiating patients with ACPE from CAP was evaluated using the receiver operating characteristic (ROC) analysis. Ninety-three patients with ACPE, 36 with CAP, and 11 with complicated ACPE/CAP were included. In patients with ACPE, edema (LR+ 5.4) was a moderate factor for rule-in, and a high brain natriuretic peptide level (LR+ 4.2) was weak. In patients with CAP, cough (LR+ 5.7) and leukocytosis (LR+ 5.2) were moderate factors for rule-in, while fever (LR+ 3.8) and a high C-reactive protein level (LR+ 4.8) were weak factors. The mean diameter of ostial PVs in patients with ACPE was significantly larger than that of patients with CAP (15.8±â€Š1.8 mm vs 9.6±1.5 mm, p< 0.01). ROC analysis revealed that an ostial PV diameter cutoff of 12.5 mm was strong evidence for distinguishing ACPE from CAP with an area under the ROC curve of 0.99 and LR+ 36.0. In conclusion, as ACPE and CAP have similar symptoms and laboratory findings, dilated ostial PVs were useful in characterizing CT images to distinguish ACPE from CAP.

Deep learning facilitates the diagnosis of adult asthma.

BACKGROUND: We explored whether the use of deep learning to model combinations of symptom-physical signs and objective tests, such as lung function tests and the bronchial challenge test, would improve model performance in predicting the initial diagnosis of adult asthma when compared to the conventional machine learning diagnostic method. METHODS: The data were obtained from the clinical records on prospective study of 566 adult out-patients who visited Kindai University Hospital for the first time with complaints of non-specific respiratory symptoms. Asthma was comprehensively diagnosed by specialists based on symptom-physical signs and objective tests. Model performance metrics were compared to logistic analysis, support vector machine (SVM) learning, and the deep neural network (DNN) model. RESULTS: For the diagnosis of adult asthma based on symptom-physical signs alone, the accuracy of the DNN model was 0.68, whereas that for the SVM was 0.60 and for the logistic analysis was 0.65. When adult asthma was diagnosed based on symptom-physical signs, biochemical findings, lung function tests, and the bronchial challenge test, the accuracy of the DNN model increased to 0.98 and was significantly higher than the 0.82 accuracy of the SVM and the 0.94 accuracy of the logistic analysis. CONCLUSIONS: DNN is able to better facilitate diagnosing adult asthma, compared with classical machine learnings, such as logistic analysis and SVM. The deep learning models based on symptom-physical signs and objective tests appear to improve the performance for diagnosing adult asthma.

Effect of Asian dust on pulmonary function in adult asthma patients in western Japan: A panel study.

BACKGROUND: Asian dust (AD) has become a major health concern. The concentration of AD is typically expressed in particulate matter less than 10 µm (PM10) and 2.5 µm (PM2.5). However, PM10 and PM2.5 consist of various substances besides AD. Light detection and ranging (LIDAR) systems can selectively measure the quantity of AD particles to distinguish non-spherical airborne particles from spherical airborne particles. The objective of this study was to investigate the relationship between pulmonary function in adult asthma patients and AD using LIDAR data. METHODS: Subjects were 231 adult asthma patients who had their morning peak expiratory flow (PEF) measured from March to May 2012. A linear mixed model was used to estimate the association of PEF with sand dust particles detected by LIDAR. RESULTS: Increases in the interquartile range of AD particles (0.018 km(-1)) led to changes in PEF of -0.42 L/min (95% confidence interval [CI], -0.85 to 0.01). An increase of 11.8 µg/m(3) in suspended particulate matter and 6.9 µg/m(3) in PM2.5 led to decreases of -0.17 L/min (-0.53 to 0.21) and 0.03 L/min (-0.35 to 0.42), respectively. A heavy AD day was defined as a day with a level of AD particles >0.032 km(-1), which was the average plus one standard deviation during the study period, and six heavy AD days were identified. Change in PEF after a heavy AD day was -0.97 L/min (-1.90 to -0.04). CONCLUSIONS: Heavy exposure to AD particles was significantly associated with decreased pulmonary function in adult asthma patients.

[A case of lung abscess due to Aspergillus viridinutans in a patient with aplastic anemia].

A 75-year-old woman with aplastic anemia was admitted to our university hospital because of a dry cough that had persisted for a month. Chest computed tomography showed a mass shadow with a central low attenuation area in the lower lobe of the left lung. Filamentous fungus resembling Aspergillus fumigatus was cultured from the specimens obtained by transthoracic needle aspiration biopsy and bronchoalveolar lavage. The initial diagnosis was a lung abscess due to A. fumigatus, although the patient did not respond well to antifungal agents. Subsequently, the filamentous fungus was identified as Aspergillus viridinutans by sequence analysis of the ß-tubulin gene, and the patient was successfully treated with combination therapy along with granulocyte colony-stimulating factor. The incidence of A. viridinutans infection is very rare. A. viridinutans is morphologically similar to A. fumigatus; however, the response to antifungal agents is generally worse than that observed in A. fumigatus infections. Therefore, the selection of agents and supplemental therapy is of vital importance in cases of A. viridinutans infection.

Construction of a Diagnostic Algorithm for Diagnosis of Adult Asthma Using Machine Learning with Random Forest and XGBoost.

An evidence-based diagnostic algorithm for adult asthma is necessary for effective treatment and management. We present a diagnostic algorithm that utilizes a random forest (RF) and an optimized eXtreme Gradient Boosting (XGBoost) classifier to diagnose adult asthma as an auxiliary tool. Data were gathered from the medical records of 566 adult outpatients who visited Kindai University Hospital with complaints of nonspecific respiratory symptoms. Specialists made a thorough diagnosis of asthma based on symptoms, physical indicators, and objective testing, including airway hyperresponsiveness. We used two decision-tree classifiers to identify the diagnostic algorithms: RF and XGBoost. Bayesian optimization was used to optimize the hyperparameters of RF and XGBoost. Accuracy and area under the curve (AUC) were used as evaluation metrics. The XGBoost classifier outperformed the RF classifier with an accuracy of 81% and an AUC of 85%. A combination of symptom-physical signs and lung function tests was successfully used to construct a diagnostic algorithm on importance features for diagnosing adult asthma. These results indicate that the proposed model can be reliably used to construct diagnostic algorithms with selected features from objective tests in different settings.

[A case of pulmonary sarcoidosis complicated with bronchial asthma that proved eosinophilic invasion].

A 33-year-old man complaining of cough admitted our hospital for examination of bilateral hilar and mediastinal lymphadenopathy. He diagnosed pulmonary sarcoidosis, because of elevation of serum angiotensin converting enzyme (ACE), epitheloid granuloma with noncaseating necrosis from transbronchial lung biopsy (TBLB) specimen, increasing of lymphocyte and elevation of the CD4/CD8 ratio in bronchoalveolar lavage fluid (BALF). Furthermore, eosinophil ratio in BALF was 3%, hyperplasia of goblet cell, eosinophilic invasion to bronchial epithelium, and thickened basal membrane were found in same biopsy specimen. He had mild reversible airway obstruction. He was diagnosed pulmonary sarcoidosis complicated with bronchial asthma. Sarcoidosis is characteristic of the T helper type 1 (Th1) mediated immune response, and bronchial asthma is characteristic of the Th2. This case histopathologically revealed that both Th1 mediated immune response and Th2 could be coexisted.

Predictive Model for Adverse Events and Immune Response Based on the Production of Antibodies After the Second-Dose of the BNT162b2 mRNA Vaccine.

BACKGROUND: The BNT162b mRNA vaccine for coronavirus disease 2019, which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), mimics the immune response to natural infection. Few studies have predicted the adverse effects (AEs) after the second-dose vaccination. We present a predictive model for AEs and immune response after the second-dose of the BNT162b mRNA vaccine. METHODS: To predict AEs, 282 healthcare workers (HCWs) were enrolled in this prospective observational study. The classification and regression tree (CART) model was established, and its predictive efficacy was assessed. To predict immune response, 282 HCWs were included in the analysis. Moreover, the factors affected by anti-SARS-CoV-2 spike protein RBD antibody (s-IgG) were evaluated using serum samples collected 2 months after the second-dose vaccination. The s-IgG level was assessed using Lumipulse G1200. Multiple regression analyses were conducted to evaluate variables associated with anti-s-IgG titer levels. RESULTS: The most common AEs after the second-dose vaccination were pain (87.6%), redness (17.0%) at the injection site, fatigue (68.8%), headache (53.5%), and fever (37.5%). Based on the CART model, headache after the first-dose vaccination and age < 30 years were identified as the first and second discriminators for predicting the headache after the second-dose vaccination, respectively. In the multiple linear regression model, anti-s-IgG titer levels were associated with age, female sex, and AEs including headache and induration at the injection site after the second-dose vaccination. CONCLUSION: Headache after the first-dose vaccination can be a predictor of headache after the second-dose vaccination, and AEs are indicators of immune response.

Granulocyte-colony-stimulating Factor-resistant Neutropenia and Polyneuropathy Presenting as Severe Complications of Sjögren's Syndrome.

Primary Sjögren's syndrome (pSS) has multi-dimensional manifestations, including neutropenia and polyneuropathy. We herein report a 76-year-old woman with pSS initially presenting as severe granulocyte-colony-stimulating factor (G-CSF)-refractory neutropenia and axonal sensorimotor polyneuropathies (SMP). Systemic glucocorticoid administration had reduced neutrophil-associated immunoglobulin G (NAIgG) on the neutrophil surface as detected using flow cytometry, resulting in the development of neutropenia. A patient with pSS concomitant with axonal SMP might show severe neutropenia as aggressive autoimmune disease. Neutropenia can be treated with systemic glucocorticoids based on the assessment of NAIgG on the neutrophil surface.

Pembrolizumab-induced aseptic meningitis in a patient with non-small cell lung cancer: A case report and literature review of aseptic meningitis as an immune-related adverse event.

Aseptic meningitis is a rare immune-related adverse event (irAE), which occurs during treatment with immune checkpoint inhibitors (ICIs). This condition has non-specific symptoms and exhibits no clear signs on magnetic resonance imaging (MRI). There are only a few reports of aseptic meningitis caused by pembrolizumab treatment for non-small cell lung cancer (NSCLC). The present study includes a report of such a case and a review of the related literature. A 67-year-old Japanese man received first-line pembrolizumab treatment for NSCLC and subsequently developed severe nausea and vomiting. No significant findings were observed following a computed tomography (CT) scan, MRI of the brain and upper gastrointestinal tract, or upper gastrointestinal endoscopy. Cerebrospinal fluid analysis revealed lymphocyte infiltration and elevation of the IgG index, without indications of metastasis or infection, which suggested the presence of aseptic meningitis. The symptoms immediately improved following prednisolone treatment, and aseptic meningitis was diagnosed as an irAE related to pembrolizumab treatment. Given that aseptic meningitis can cause non-specific symptoms, including headache and nausea, the possibility of an irAE should be considered in patients with non-specific symptoms who are receiving ICIs, and a cerebrospinal fluid examination should be performed.

Physical Characteristics of Injection Site Pain After COVID-19 mRNA BNT162b2 Vaccination.

BACKGROUND: BNT162b2, an mRNA COVID-19 vaccine, was launched in many countries as an intramuscular vaccination for COVID-19 infection. Few studies have assessed the physical indications of pain at the immunization site. This study aimed to characterize pain at the injection site and investigate morphological attributes using ultrasound. METHODS: Forty-three of 211 healthcare workers who received a second dose of BNT162b2 between February 2021 and March 2021 were enrolled in the study. The mean age of the subjects was 40 years. We evaluated patients' pain at the injection site using the Numerical Rating Pain Scale (NRPS). We also assessed the thickness of the deltoid muscle fascia at the injection site by ultrasound. Bayesian robust correlation was employed to explore the relationship between the pain intensity scores and ultrasound measurements. RESULTS: All eligible subjects complained of pain at the injection site. A median pain onset of 8 hours post-vaccination and a median peak intensity score of 4 were reported. Onset of relief occurred after 2 days. Ultrasound images demonstrated a 2.5-fold increase in fascia thickness at the injection site without intramuscular echogenicity change in all subjects. A correlation was established between the NRPS score and the non-injection-to-injection-side ratio of fascia thickness at the injection site (rho = 0.66). CONCLUSION: A sore arm was the most prevalent side effect of BNT162b2 vaccination and could be attributed to temporal fasciitis.

Characteristic appearance of the oropharynx in patients with postnasal drip (PND)-induced cough.

INTRODUCTION: Post-nasal drip (PND)-induced cough is a common cause of chronic cough. However, there is little known about the characteristic physical findings of this condition. OBJECTIVES: We investigated views of the pharyngeal wall in patients with PND-induced cough using a handy endoscopic images. METHODS: The subjects were 135 consecutive patients referred to our hospital with a sensation of something "dripping down the throat" as one of their symptoms. Physical findings for the oropharynx were examined using Wi-Fi endoscope camera. The difference in probability of symptoms in patients with acute cough and those with subacute/chronic cough was assessed using a Bayesian Fisher exact test on a 2 × 2 table. RESULTS: Among the patients, 105 (78%) complained of cough, 78 (58%) of acute cough, 20 (15%) of subacute cough, and 7 (5%) of chronic cough; and 71 (53%) had coexisting asthma. Using Bayesian inference, a sore or scratchy throat and fever were more common in patients with acute cough than in those with subacute/chronic cough. In endoscopic images of the oropharynx, a reddish curtain sign on the posterior pharyngeal wall behind the palatopharyngeal arch was found in 121 patients (90%). CONCLUSION: Patients with acute PND-induced cough have a component of acute upper respiratory infection, because of high probability of a sore or scratchy throat and fever as symptom. A reddish curtain sign may be a useful finding for identifying PND-induced cough in these cases.

[A relapse of acute bird-related hypersensitivity pneumonitis due to the use of a feather duvet by a housemate].

In December 2007, a 78-year-old woman was admitted to our hospital complaining of cough and low-grade fever for 1 month. We performed various medical tests and diagnosed acute hypersensitivity pneumonitis. We suspected that the cause of illness was the prolonged use (10 years) of a feather duvet. She was treated with corticosteroids and was advised to avoid using feather duvets. This treatment improved her symptoms. However, she relapsed after 1 year. She had never used a feather duvet since the last admission, but her housemate used a feather duvet in the same room during winter. Bronchoalveolar lavage revealed lymphocytosis. Specific antibodies against pigeon and budgerigar-dropping extracts were present in her serum. On the basis of these findings, we diagnosed acute bird-related hypersensitivity pneumonitis. This condition is rarely caused by indirect exposure. Therefore, we reiterate the significance of obtaining of a detailed medical history to identify relevant antigens.

[Primary pulmonary cryptococcosis with multiple infiltrative shadows complicated by obstructive sleep apnea syndrome].

In November 2007, a 30-year-old obese woman was admitted to our hospital with a complaint of persistent dry cough. Her chest-X-ray and computed tomography revealed multiple infiltrative shadows with air bronchograms in all lung fields. The bronchoalveolar lavage fluid revealed small bodies of Cryptococcus species. Cryptococcal serum antigen was also positive. To examine the cause of her snoring, polysomnography was done and revealed obstructive sleep apnea syndrome. The patient was given a diagnosis of primary pulmonary cryptococcosis with obstructive sleep apnea syndrome. After 12 months of treatment with fluconazole, the infiltrative shadows disappeared. Pulmonary cryptococcosis should be considered in the differential diagnosis of pulmonary multiple infiltrated shadows in patients without immunological abnormalities.

Antibody-dependent cellular cytotoxicity mediated by cetuximab against lung cancer cell lines.

PURPOSE: Epidermal growth factor receptor (EGFR) is commonly overexpressed in lung cancer. Cetuximab is a chimeric mouse-human antibody targeted against EGFR. Compared with its inhibitory properties, its immunologic mechanisms have not been well studied. In this study, we investigated the antibody-dependent cellular cytotoxicity (ADCC) activity of cetuximab against lung cancer cell lines. EXPERIMENTAL DESIGN: We studied the correlation between EGFR expression in lung cancer cell lines and the ADCC activity of cetuximab as well as the influence of interleukin-2 and chemotherapy on the ADCC activity. EGFR expression was measured by a quantitative flow cytometric analysis and immunohistochemistry. The ADCC activity was assessed by a 4-h (51)Cr release assay. Peripheral blood mononuclear cells, purified T cells, natural killer (NK) cells, and monocytes from healthy donors or lung cancer patients were used as effector cells. RESULTS: Fresh peripheral blood mononuclear cells exhibited cetuximab-mediated ADCC activity against lung cancer cell lines at a low concentration of cetuximab (0.25 microg/mL). A logarithmic correlation was observed between the number of EGFRs and ADCC activity. Even low EGFR expression, which was weakly detectable by immunohistochemistry, was sufficient for maximum ADCC activity, and further increases in EGFR expression on the target cells had no further effect on the ADCC activity. In addition, ADCC activity was enhanced by interleukin-2 mainly through activation of NK cells and was less susceptible to immunosuppression by chemotherapy than NK activity in lung cancer patients. CONCLUSIONS: These observations suggest the importance of ADCC activity as an immunologic mechanism of cetuximab in biological therapy for lung cancer patients.

[A case of endobronchial actionomycosis evaluated by FDG-PET].

In April 2005, a 78-year-old man was admitted to our hospital because an abnormal chest shadow had been noted on a medical examination. Our investigation revealed primary squamous cell lung carcinoma in the right lower lobe (stage IIIA). Right middle and lower lobectomies including resection of the chest wall were performed. 18Fluorodeoxyglucose-positron emission tomography (FDG-PET) conducted 18 months later demonstrated nodular lesions with intense FDG activity in the right upper lobe and the presence of a post-resection positive bronchial stump. Fiberoptic bronchoscopic examination revealed a pus-coated mass located in the endobronchial lesion, and Actinomyces was identified in a biopsy specimen of the mass. Endobronchial actinomycosis was diagnosed. An FDG-PET examination conducted after the patient was treated with amoxicillin (AMPC) for 2 months, did not indicate any FDG activity in the endobronchial lesion.

Physical Signs and Clinical Findings Before Death in Ill Elderly Patients.

Few studies have examined variations in both the physical signs and clinical findings in the final days and hours before the death of elderly patients. We determined the physical signs and clinical findings in patients who were at least 75 years old or were diagnosed with cancer with impending death and examined the association of these parameters with the profile and timing of their endocardiography (ECG) and oxygen saturation (SpO2) changes prior to death. In this prospective, observational study, between April 2014 and June 2017, we enrolled elderly patients who were admitted to the Respiratory Medicine Ward in our hospital and were near death, which was determined based on certain symptoms such as a loss of oral intake. We recorded their physical signs (oral intake, consciousness level, and respiration with mandibular movement) 4 times a day from admission to death. We evaluated their changes in ECG and in SpO2 levels for up to 24 hours preceding death. For the 70 patients who died in our ward, we found a loss of oral intake at 6 days, consciousness impairment at 1.3 days, and then respiration with mandibular movement at 12 hours before death were the most consistent findings before death. When we analyzed the ECG and SpO2 changes during impending death, 83% of the patients showed undetectable SpO2 levels followed by a loss of heart rate. The loss of P wave in the ECG was characterized as process on impending death. Respiration with mandibular movement was one of the specific signs of impending death in ill elderly patients. The monitoring of ECG and SpO2 levels may be a useful tool to predict the impending time of death.

Acute-phase reaction induced by zoledronate and its effect on prognosis of patients with advanced non-small cell lung cancer.

OBJECTIVES: Zoledronate (ZOL) is usually used for prevention of skeletal-related events in cancer patients with bone metastases. The first administration of ZOL is occasionally associated with development of acute-phase reaction (APR), which is due to activation of γδ T cells. ZOL-related APR was associated with better overall survival (OS) of patients with non-small cell lung cancer (NSCLC) in our previous retrospective study. However, it remains to be clarified whether γδ T cells are more activated in patients who experienced ZOL-related APR, and whether γδ T cell activation is involved in prolongation of OS. MATERIALS AND METHODS: Twenty-three patients with advanced NSCLC were recruited between 2012 and 2014 in this study. We administered ZOL to participants with standard care. The patient characteristics, change in γδ T cell counts and cytokines, OS, and skeletal-related event-free survival were compared between patients with APR (APR group) and those without APR (non-APR group). RESULTS: Ten patients (43.5%) experienced a ZOL-related APR. The number of γδ T cells at baseline in the APR group was significantly higher than that in the non-APR group. Serum interleukin-6 and tumor necrosis factor-α in the APR group were significantly increased, but no change in the number of γδ T cells was observed after the first administration of ZOL in both groups. OS in the APR group was significantly longer than that in the non-APR group (median survival time: 23.1 vs. 14.5 months, p < 0.01). CONCLUSION: We showed that APR is related to higher numbers of γδ T cells at baseline and increased cytokines after the first ZOL administration, but not to proliferative responses of γδ T cells. In addition, better OS was observed in the APR group. Therefore, the number of γδ T cells might be a prognostic marker in patients with NSCLC.

Diverse activation states of RhoA in human lung cancer cells: contribution of G protein coupled receptors.

Rho GTPases play an essential role in the control of various cellular functions. Accumulating evidence suggests that RhoA overexpression contributes to human cancer development. However, the activation states of RhoA are poorly defined in cancer cells. In this study, we examined both the expression levels and the activation states of RhoA in various lung cancer cells by quantitative real-time reverse transcriptase-polymerase chain reaction and in vivo Rho guanine nucleotide exchange assay, respectively. Moreover, we dissected the signaling pathway from the cell surface receptors to RhoA using a broad-spectrum G protein coupled receptor (GPCR) antagonist, [D-Arg1,D-Trp5,7,9,Leu11]Substance P (SP), and a recently reported Galphaq/11-selective inhibitor, YM-254890. We found that RhoA was expressed highly in large cell carcinoma cells but only weakly in adenocarcinoma cells. The activation states of RhoA are considerably different from its expression profiles. We found that four of six small cell lung carcinoma (SCLC) cell lines exhibited a moderate to high activation rate of RhoA. The addition of [D-Arg1,D-Trp5,7,9,Leu11]SP reduced RhoA activity by almost 60% in H69 SCLC cells. The addition of YM-254890 had no effect on RhoA activity in H69 cells. Our results suggest that RhoA is activated in various lung cancer cells independent of its expression levels, and the high activation state of RhoA in SCLC cells mainly depends on a neuroendocrine peptide autocrine system which signals through Galpha12 coupled GPCR to RhoA. This study provides new insights into RhoA signaling in lung cancer cells and may help in developing novel therapeutic strategies against lung cancer.

[Use of QuantiFeron TB-2G test on high-risk groups for tuberculosis infection at our hospital].

PURPOSE: To investigate the infection rate of tuberculosis in high-risk employees at our hospital. METHODS: We measured interferon gamma levels in 40 employees and evaluated the infection rate in doctors working in the Tuberculosis Ward (D group), nurses in the Tuberculosis Ward (N group), and other high-risk employees (O group). RESULTS: The overall infection rate including probable infection was 6/40 (15.0%). The infection rate in the N group was 0%, while those in the D and O groups were 27.3% and 20.0% respectively. No new infection of tuberculosis was observed after the introduction of tuberculosis infection measure manual of our hospital. CONCLUSION: Our hospital's tuberculosis infection measure manual was effective in decreasing the new tuberculosis infection despite a high infection rate in high-risk employees at our hospital.

[Case of liver tuberculosis requiring differentiation from liver metastasis of cancer].

A 79-year-old woman was admitted to our hospital because of general fatigue. Chest radiograph and computed tomograph showed bronchiectasis and centrilobular nodules in the right middle lobe and lingula, which had not changed from previous examination. Intrahepatic nodular lesions and swelling of the left cervical lymph nodes, supraclavicular lymph node, abdominal paraaortic lymph nodes and inguinal lymph nodes was observed. Biopsy specimen of the liver lesion demonstrated epithelioid cell granulomas. Biopsy of the right inguinal lymph node demonstrated epithelioid cell granulomas with caseous necrosis and culture of the specimen showed Mycobacterium tuberculosis. The patient was diagnosed as having liver tuberculosis and multiple tuberculous lymphadenitis. Antituberculous treatment with isoniazid, rifampicin, ethambutol and pyrazinamide were started and continued for 6 months. All lesions improved after treatment. This was a rare case of liver tuberculosis that was difficult to distinguish from liver metastasis of cancer.
