[Abdominal lymph node tuberculosis: diagnostic value of echography and x-ray computed tomography].

The aspects of abdominal ultrasonography and computed tomography (CT) were studied in 4 patients (3 African and 1 Haitian) with abdominal tuberculosis. All were markedly debilitated and three patients had protracted fever. Tuberculosis was documented in all cases by demonstrating Mycobacterium tuberculosis in cultures of lymph nodes taken during laparotomy and/or cultures of products of gastric aspiration. Ultrasonography showed enlarged lymph nodes in the pancreatic and peripancreatic areas and also in the mesenteric, perivascular and hepatic pedicle areas. CT showed hypertrophied lymph nodes with low tissue density ranging from 20 to 35 Hounsfield units. Although non pathognomonic, these aspects were suggestive of tuberculosis. Intravenous contrast medium administration failed to increase the density in the center of lymph nodes but disclosed the existence of a thick hyperdense rim surrounding the hypodense center of the caseous lymph nodes. Repeated ultrasound and CT examination allowed to control the efficacy of antituberculous chemotherapy.

[Lymph node tuberculosis in HIV-1 seropositive patients in Central Africa. A characteristic histopathologic picture].

Sixty two patients fulfilling the definition established by the Centers for Disease Control in 1982 for persistent lymphadenopathy syndrome, thought to be related to the human immunodeficiency virus (HIV) infection, were selected at the Butare university hospital, in Rwanda, between 1987 and 1988. Forty-five (73%) of them were indeed seropositive. Fifteen patients of sixty two (24%) presented unexpectedly evidence of tuberculous adenitis on biopsy. Three of them, found HIV-1 seronegative, showed a classical follicular adenitis, whereas the twelve other seropositive patients presented unusual histologic features, consisting of more or less immature tuberculoid granulomas with an abundant caseating and often granular necrosis, containing acid fast bacilli. Numerous blood vessels and abundant plasmacytosis were found in non-necrotic areas. Semi-quantitative evaluation of the granulomatous reaction components provided a histological spectrum probably related to the degree of impairment of the cellular immune response, which could be of prognostic significance. In areas where populations are exposed to both HIV and M. tuberculosis, it appears that lymph node biopsy with mycobacterial culture should be recommended in order to detect occult tuberculosis among HIV-seropositive persons, allowing accurate medical care and adequate public health surveillance.

[A case of cervical and mediastinal lymph nodes tuberculosis, tuberculous pleurisy, spinal caries and cold abscess in the anterior chest wall].

A 61-year-old woman with schizophrenia that had been treated in a psychiatric hospital was admitted to our hospital because of subileus and back pain. Though subileus was improved, she had a sudden attack of fever 7 days later and developed right pleural effusion, a cold abscess in the anterior chest wall and swelling of a thumb-sized right cervical lymph node which broke through the skin. We made a diagnosis of cervical and mediastinal lymph nodes tuberculosis, tuberculous pleurisy, spinal caries and cold abscess in the anterior chest wall due to the biopsy findings of the specimen taken from the cervical lymph node, examination of pleural effusion, chest CT, bacteriological examination of the cold abscess and spinal MRI. We started chemotherapy with the antituberculous drugs (HRSZ) and symptoms except back pain improved. She complained of paresis of the both lower extremities, which completely paralyzed 8 months later in spite of continued chemotherapy. Thereafter her paralysis was gradually improved and she was able to walk by herself after 12 months chemotherapy.

[Some problems in diagnosis of peripheral lymph nodes tuberculosis].

The structure of lymphadenopathies has been determined by biopsies of peripheral lymph nodes. The parameters are different in general and specialized prosectorship. Malignant diseases (34.0%), reactive hyperplasias (24.3%), and tuberculosis (only in 6.0%) were verified in the general prosectorship. Tuberculosis was detected in 61.3% at the phthisiological center. The problems of diagnosis of lymphadenopathies of various etiology are discussed.

[Hypercalcemia in florid pulmonary and cervical lymph node tuberculosis].

A 57-year-old man with a history of tuberculosis (TB of the knee-joint 44 years ago and open pulmonary TB six months ago with poor patient drug compliance) had lost 10 kg in weight during the preceding six months. In addition, firm lymph-node swellings with redness of the overlying skin and a skin fistula developed on the right side of the neck. There was mild hypercalcaemia (albumin-corrected serum calcium concentration 2.59 mmol/l) and hyperphosphataemia (2.0 mmol/l) with low-normal serum concentrations of parathormone and of 25-hydroxy-vitamin D3 (14 ng/ml). Serum 1,25-dihydroxy-vitamin D3 concentration was reduced (16 ng/l). The activity of osseous isoenzyme of alkaline phosphatase was normal (19 U/l) and skeletal scintigraphy revealed no abnormality. The cervical lymph-nodes were excised (histology: active caseous lymph-node TB). Tuberculostatic treatment was begun with daily doses of 0.3 g isoniazid, 0.45 g rifampicin, 1.2 g ethambutol and 1.5 g pyrazinamide. Serum calcium concentration rose to 3.22 mmol/l (albumin-corrected) in the first two weeks, even though the patient was on a low-calcium diet. The various concentrations subsequently decreased, but remained slightly elevated throughout the period of observation (11 weeks). This is thus a case of TB-associated hypercalcaemia which was not caused by 1,25-dihydroxy-vitamin D3 or bone destruction.

[Dysphagia with fever revealing mediastinal lymph node tuberculosis. Apropos of 2 cases].

The oesophagus is a rare localization of extrapulmonary tuberculosis. We report 2 cases of tuberculous mediastinal lymph nodes revealed by dysphagia and fever in immunocompetent subjects. With the actual outbreak of tuberculosis, this localization is worth mentioning, as the precocity of the diagnosis and the therapeutic handling is an important prognostic factor.
