Cerebral Abscess – Sequel of Septic Embolization from Thrombo- Phlebitis at Venous Catheter Insertion Site

摘要

A 26-year-old female patient was referred to theDepartment of Radiology & Imaging for a CT scan.Plain and post-contrast images were obtained in axial,coronal and sagittal planes by SIEMENS SOMATOM328 slice CT scanner. There were multiple rimenhancing irregular outlined round cavities (average+ 27 HU) with marked disproportionate perilesionaledema in bilateral parietal lobes, largest one measuringabout 2.5 × 2.5 × 2 cm, located in right parietal lobe.Mass effect was present, evidenced by 4.5 mm midlineshift to left and compression over right lateral ventricle.Since disproportionate perilesional edema is a verymuch characteristic fnding of metastasis, we includedcerebral metastases in our differential diagnoses.Due to the fact that metastasis is very much unlikelyat this young age unless there is a known primarymalignant neoplasm, we considered cerebral abscessesas a potential imaging diagnosis as well. Besides,tuberculomas were also kept in mind since this regionis endemic for tuberculosis.
