| Abstract|| |
A 58-year-old female with a history of recurrent pneumonia was evaluated for fevers, right lower back pain, and hematuria. A noncontrast abdominal computed tomography (CT) scan showed air and fluid-filled area in the right lower lobe for which a contrast-enhanced CT chest was performed. The CT of the chest revealed the cystic mass was supplied by an anomalous artery from the descending aorta. The patient was then diagnosed with a superinfected bronchopulmonary sequestration which was treated with surgical resection.

A 58-year-old female with a history of recurrent pneumonias in adolescence presented with recent fevers sharp right lower back pain and hematuria. Except for tachycardia (103 beats/min) physical examination and vitals were unremarkable. Laboratory testing revealed a WBC count of 22.4 k/ml (normal 4–12 k/ml) air and fluid-filled area in the right lower lobe (RLL), and the patient improved after surgical resection, procalcitonin of 2.6 ng/mL (normal <0.05 ng/mL) and hemoglobin of 12.8 mg/dL (normal 12–16 mg/dL). A non-contrast abdominal computed tomography (CT) scan demonstrated blood clots in the bladder and a cystic, suspicious for an intrapulmonary abscess. A subsequent contrast-enhanced chest CT scan revealed the cystic mass was supplied by an anomalous artery from the descending aorta. Also noted was a small ipsilateral pleural effusion and RLL consolidation consistent with pneumonia. An intrapulmonary abscess was diagnosed [Figure 1] and [Figure 2].

| Question|| |
What is the pathognomonic radiographic feature? What is the radiographic diagnosis?
| Answer|| |
The anomalous artery from the descending aorta directly supplying the cystic mass is the pathognomonic feature. The diagnosis is a bronchopulmonary sequestration (BPS). This patient's BPS was super infected, resulting in a pulmonary abscess that required resection.
BPS is extremely rare, comprising 0.15%–6.4% of congenital pulmonary anomalies. It is left side predominant and of two types – extralobar sequestration (ELS) and intralobar sequestration (ILS). ELS is more common in infancy, presenting as respiratory distress and can rarely be extra-thoracic. ILS is more frequent, presents later in life, and often with recurrent infections. These can become cystic, as with our patient. BPS is often missed and goes undiagnosed for decades. It is rarely complicated by hemorrhage or lung cancer. Multidetector CT best delineates the airways and parenchyma and is the test of choice to follow BPS. Contrast CT or pulmonary angiography best detects it given the hallmark systemic arterial supply. The management of asymptomatic BPS in infants and children is controversial. Some authors advocate excision to prevent complications in adulthood while others recommend close follow-up with serial imaging. Surgical excision is the treatment of choice for those with symptoms.
