Although Tuberculosis (TB) is very common in early childhood, we see an increased incidence of TB in adolescents due to increased susceptibility. It is also important to note that adolescent TB affects those living in low/middle income countries where TB is very common. There is a paucity of literature regarding the sequelae of TB disease in adolescents based on advanced cross-sectional imaging. We aimed to review the imaging features seen on CT imaging of the chest post adolescent TB in a cohort of patients from Peru. Read More

Suspected airway compression in symptomatic children with Lymphobronchial Tuberculosis (LBTB) can be diagnosed using modern computed tomography (CT) assisted by coronal minimum intensity projection (MinIP) reconstructions. The accuracy of plain radiographs in detecting airway compression in children with TB has not been evaluated against an imaging gold standard in a dedicated manner.

We aimed to compare frontal CXR against thick-slab angled coronal CT MinIP in identifying airway stenosis at ten specific sites and to determine the agreement between the modalities regarding the degree of stenosis. Read More

Diagnosing paediatric TB can be challenging due to non-specific signs and symptoms and difficulties in getting a microbiological confirmation. Diagnosis relies mainly on symptoms and chest X-ray (CXR), with hilar or mediastinal lymphadenopathy as the most common finding. However, CXR has poor inter- and intra-reader agreement for mediastinal lymphadenopathy. Ultrasound (US) does not expose children to ionizing radiation; is repeatable and due to the recent development of portable, low-cost US machines it can be used at the point of care and is cost-effective.
We investigated clinician-performed mediastinal US, comparing with CXR, for the detection of lymphadenopathy in children with suspected pulmonary TB. Read More

In 2017, children under the age of 15 accounted for only 10% of the 10 million Mycobacterium tuberculosis (TB) infections estimated by the World Health Organization. Child carriers of TB pose health risks to their adult caregivers, and children can exhibit greater susceptibility to significant health risks from the infection. Nontuberculous mycobacterial (NTM) infection presents disparate health risks and can generate imaging specific findings. This presentation addresses radiologic manifestations of mycobacterial disease as a means to educate pediatric radiologists given the medical significance of mycobacterial infection. Read More

Diagnosing pediatric pulmonary tuberculosis (PTB) may be challenging as getting microbiological confirmation is difficult. Chest X-Ray (CXR) involves radiation exposure and has poor inter-reader agreement. Mediastinal lymphadenopathy can also be detected by mediastinal ultrasound (US). We describe technical aspects of performing mediastinal US and the findings in children with suspected PTB. Read More

El abdomen es el sitio más común de tuberculosis extraperitoneal, siendo las linfadenopatías mesentéricas y peripancréaticas, la manifestación más frecuente en hasta el 55-65% de pacientes. La tomografía es el principal método de imagen usado para su evaluación.
La presencia de obstrucción biliar, gastrointestinal o genitourinaria sugiere un diagnóstico alternativo.

Tuberculous meningitis (TBM) causes significant morbidity and mortality in young children. Early treatment can be initiated with MR imaging diagnosis. We present MR detectable miliary meningeal TB in two patients presenting in a developed world setting.
Case 1: A 9 y/o girl of Haitian descent, developed fevers, cough, lethargy and seizures. Brain MRI demonstrated multiple, small, T2-dark, rim-enhancing lesions, associated with cranial nerve and leptomeningeal enhancement. Chest CT showed mediastinal lymphadenopathy, multiple small interstitial lung nodules and a splenic hypo enhancing lesion. CSF showed pleocytosis, low glucose, and high protein. She was started on 4-drug treatment for TBM and dexamethasone. Serial bronchoalveolar lavage was Xpert MTB/RIF and acid-fast negative. Contact tracing revealed a remote positive contact with pulmonary tuberculosis from Haiti. Endobronchial US-guided biopsy of a subcarinal lymph node was positive for Xpert MTB PCR.

Case 2: A 17 y/o female with Crohn’s disease on adalimumab developed refractory ear infections despite multiple courses of antibiotics and underwent myringotomy, with negative aerobic ear fluid culture. She had two chronic skin lesions. Brain MRI, obtained due to persistent otorrhea, showed multiple, small, round, T2-dark lesions. CSF studies were unremarkable. CT chest, abdomen and pelvis showed left upper lobe tree-in-bud nodules, hypoattenuating splenic lesions and a left obturator internus abscess with adjacent osteomyelitis. She underwent CT guided aspiration of the obturator muscle collection, bronchoscopy with Bronchoalveolar Lavage (BAL), biopsy of her skin lesions and ear fluid aspiration. QuantiFERON Gold was positive. Ear fluid was Xpert MTB/RIF assay and acid-fast stain positive. She was started on 4-drug therapy and prednisone. Cultures from the ear fluid, skin tissue, muscle tissue and BAL showed growth of acid-fast bacilli.

TB meningitis is most often due to blood borne spread of the disease from the lungs which may result in miliary nodules in the leptomeninges and brain. The two cases presented illustrate that although TBM is unusual in a developed world, we should suspect it in children of migrants as well as in patients with immunosuppression, where atypical imaging patterns including lack of typical basal enhancement and presence of miliary meningeal nodules may be seen.
