Incidental finding of an aberrant left pulmonary artery, an aberrant right subclavian artery, and a tracheal bronchus in an adult woman with a meningioma and a history of medulloblastoma.

The aberrant left pulmonary artery and the aberrant right subclavian artery are rare congenital vascular anomalies, and the tracheal bronchus is a rare congenital respiratory anomaly. A 33-year-old female patient, with a history of desmoplastic medulloblastoma, was surgically treated at our hospital for a meningioma. On the second postoperative day, the patient complained of shortness of breath and chest pain. Contrast-enhanced multislice computed tomography was negative for pulmonary embolism, but incidentally revealed all three congenital anomalies. In our report, we detail this exceedingly rare case.

Bilateral primary psoas abscesses due to methicillin-resistant Staphylococcus aureus in a neutropenic patient: a case report.

BACKGROUND: Pyogenic abscess of psoas muscles is a rare condition. Psoas abscess due to methicillin-resistant Staphylococcus aureus is an emerging and rare infection and so far the related data are scarce. CASE PRESENTATION: We report the rare case of primary and bilateral large psoas abscesses due to methicillin-resistant Staphylococcus aureus in a 54-year-old Arab Jordanian woman with breast cancer who had neutropenia after starting chemotherapy. She was diagnosed 50 days after onset of symptoms. However, despite this delay in diagnosis and the large size of the abscesses, she had a full recovery. She was treated with antibiotics and percutaneous drainage and was doing very well at a follow up of 18 months. CONCLUSIONS: Psoas abscess due to methicillin-resistant Staphylococcus aureus might have insidious presentation with extensive disease especially in immunocompromised patients. However, it can be managed effectively with percutaneous catheter drainage and appropriate antibiotic therapy.
