Case Report: Bacillary Angiomatosis with Massive Visceral Lymphadenopathy

ABSTRACT Bacillary angiomatosis is a newly characterized infectious disease occurring mainly in patients with AIDS. Most patients have cutaneous angiomatosis lesions resembling Kaposi’s sarcoma or pyogenic granuloma. Although the disease may be life-threatening if not treated, it is curable with appropriate antibiotic therapy. A patient had a fever, nightsweats, abdominal pain, pleural effusions, and asymmetric peripheral lymphadenopathy. Computed tomography of the chest and abdomen revealed a unique pattern of enhancement of lymph nodes that, to this research team’s knowledge, has not been reported previously with this condition. Appropriate antibiotic therapy resulted in a complete resolution of the disease. Included is a discussion of the clinical presentation, etiology, histology, and treatment of bacillary angiomatosis.
