“…The sonographic and CT findings of abdominal tuberculous lymphadenopathy have been described by many investigators [1][2][3][4][5][6][7][8][9][10][11][12], such as a hypoechoic nodular lesion in abdominal sonography and peripheral enhancement with low-density centers on contrast-enhanced CT. Moon et al [13] reported a clinicopathologic correlation with the MRI appearance of mediastinal tuberculous lymphadenitis.…”

“…On CT, ascitic fluid has high attenuation values (20±45 HU) in most of the patients [18,19,24,28,35,36]. This can be explained by high protein and cellular contents [21,23,28].…”

“…Computed tomography fails to show multiple, thin interlacing septa in most patients, especially in the subdiaphragmatic and pelvic regions. Ultrasound enables delineation of multiple, thin, and mobile septa and debris in the ascites [28,29,30,36]. The enhancement of ascites on MRI obtained 15±20 min after intravenous administration of Gd-DTPA is not an uncommon finding in exudative ascites, but this sign was noted in 1 of 2 patients with tuberculous peritonitis [38].…”

The concept of "abdominal tuberculosis" in this review refers to peritoneum and its reflections, gastrointestinal tract, abdominal lymphatic system, and solid visceral organs, as they are subject to varying degrees of involvement alone or in combination. Some features, including free or loculated ascites with thin-mobile septa, smooth peritoneal thickening and enhancement, misty mesentery with large lymph nodes, smudged omental involvement, and advanced ileocecal changes demonstrated by US, CT, or gastrointestinal series are deemed suggestive radiological findings. The diagnosis still requires a high index of suspicion, once the suggestive features have been demonstrated by imaging modalities.

“…On abdominal ultrasound examination, the most suggestive findings are multiple small (< 1 cm), round hypoechogenic images, which are frequently hypodense on abdominal CT [6,8,11,21,26,[43][44][45][46][47][48][49][50]. Splenomegaly [6,27,[51][52][53][54] is also seen, and it is considered to be the most common feature of splenic involvement [55]. However, some reports point out the possibility of presentation with uniloculated pseudotumoral macronodules [5,6,11,22,46,56,57].…”

We describe a case of a male patient, 38 years old, HIV-positive (most recent CD 4 count about 259/ mm 3 ), with abdominal pain, nausea, vomiting, anorexia, weight loss, and vespertine high fever with chills. His hemogram showed normocytic and normochromic anemia, with a high erythrocyte sedimentation rate (ESR) and gross granulations in the neutrophils. Transaminases were normal. Bone marrow biopsy evidenced a chronic disease anemia pattern and a lack of infectious agents. Abdominal ultrasound examination showed a normal-size spleen, which exhibited heterogeneous parenchyma and multiple small hypoechoic images, together with small ascites, peripancreatic and para-aortic lymphadenopathy. These findings were confirmed by abdominal CT. The liver was normal in size, but had a hyperechoic image, which was not visualized on CT. Histopathological analysis of one of the multiple abdominal lymph nodes obtained by laparoscopic biopsy exhibited a chronic granulomatous inflammatory process, with caseous necrosis. Tissue sections were positive for BAAR (acid-alcohol-resistant bacillus), and the cultures were positive for Mycobacterium tuberculosis. Antituberculosis treatment was begun, and the patient evolved with improvement of his general state, fever remission and weight gain. Splenic tuberculosis is a rare disease, occurring predominantly in patients in late stages of AIDS and/or disseminated tuberculosis. It is a difficult diagnosis, since there are no specific findings. Hence, complementary examinations, such as abdominal ultrasound/ CT, or fine needle aspiration, are usually necessary for investigation and differential diagnosis. Often, lesion regression after anti-tuberculosis regimens can be seen, and splenectomy is restricted to complicated or refractory disease.
