| 1. | Cholesterol clefts or asteroid bodies are present within or outside granulomas.
|
| 2. | Radiographically it is virtually impossible to differentiate granuloma from a cyst.
|

|
| 4. | The macrophages in granulomas are often referred to as " epithelioid ".
|

|
| 6. | Nevertheless, necrotizing granulomas are a hallmark of this disease.
|
| 7. | Brain infection can cause granulomas, hematomas, and abscesses.

| 8. | The granulomas are small, sparse, and without caseation.
|
| 9. | One study has suggested a correlation between pyogenic granuloma and Bartonella seropositivity.
