Tuberculosis (TB) is no longer a disease limited to developing nations and is still a major cause of significant morbidity and mortality worldwide. The indolent clinical presentation, emergence of multidrug-resistant mycobacteria, and association with human immunodeficiency virus infection poses obstacles for early diagnosis and management. Compared with the other forms of TB, musculoskeletal involvement is relatively rare. Tuberculous spondylitis is the most common form of musculoskeletal TB and accounts for ~50% of cases. Extraspinal musculoskeletal TB shows a predilection for large weightbearing joints, long bones, and the skull. This article reviews the radiologic features of diverse forms of osseous TB and the diagnostic value of the different imaging techniques. It also reviews the imaging differential diagnoses, including other infections and malignancies/metastases. Conventional radiography is of key value in the diagnosis of musculoskeletal TB. Computed tomography, magnetic resonance imaging, and bone scintigraphy also play key roles in the early detection of disease and in demonstrating the extent of disease process and soft tissue involvement. Because delay in treatment significantly reduces the cure rate and increases the rate of complications and morbidity, early radiological diagnosis of TB is of paramount importance for appropriate management.

Pseudoangiomatous stromal hyperplasia (PASH) is a benign breast disorder with the tumoral variety being extremely rare. We report a rare case of synchronous, massive axillary and breast tumoral PASH in a 55-year-old post-menopausal woman. Mammography, ultrasonography and sonoelastography features are illustrated with histopathological correlation. A high-grade invasive ductal carcinoma was detected in the contralateral breast on annual follow-up imaging. Radiologists need to be familiar with the imaging appearances of PASH and be aware of its association with subsequent cancer risk. To the best of our knowledge, the present case of synchronous tumoral PASH in the breast and axillary tissue is the second reported case till now.

Intraosseous hemangiomas are rare, benign bone tumors usually affecting the bones of the axial skeleton. Its incidence in the long bones is extremely rare. We report a 19-year-old boy with solitary intraosseous hemangioma of the proximal ulna. Radiographs and computed tomography images showed a well-defined osteolytic lesion involving the right proximal ulna. Magnetic resonance imaging showed intermediate signal intensity on T1-weighted images and increased signal intensity on T2-weighted images with internal trabeculae and peripheral post-contrast enhancement. Postcurettage histologic diagnosis of intraosseous hemangioma was made.

Highlights Avoiding transmission of COVID-19 pandemic while providing essential breast cancer care is critical. Tailored recommendations and algorithms have been developed promptly at the breast imaging department to face the COVID-19 pandemic outbreak. Discussions are underway on the best way to resume regular patient care, given the uncertainty course and duration of the COVID-19 pandemic.
