Musculoskeletal ImagingBacillary angiomatosis
a disorder characterized by presence of numerous bacilli along with
vascular proliferation in affected tissues, such as the skin, bone,
lymph nodes and brain. The organisms causing bacillary angiomatosis and the related disorder bacillary peliosis are similar to those causing cat-scratch disease.
Patients with the human immunodeficiency virus HIV infection may develop bacillary angiomatosis, manifested as a cutaneous disorder with multiple angiomatous papules, skin lesions typical of Kaposis sarcoma, cellulitis and subcutaneous nodules.
Bone lesions are sometimes the initial manifestation of the disease. Radiographically, the dominant feature is osteolysis, associated with an adjacent soft tissue mass. Also, see angiomatosis
