Abstract:
We experienced with a relatively rare case of an aneurysmal bone cyst (ABC) arising in the left rib. A 34-year-old female, had experienced chest discomfort on the left anterior side and pain for 1 year. A chest X-ray suggested a left chest wall tumor involving the ribs. Computed tomography (CT), magnetic resonance imaging (MRI) and a bone scintigram revealed an expansive tumor of the anterior portion of the left 4th rib involving the 3rd and 5th rib with "blow out appearance" and "fluid-fluid level". Wide excision of the tumor and adjacent muscle tissue was performed with an antero-axillary incision. Chest wall reconstruction was performed with prolene mesh (140 x 90 mm). The resected specimen showed an encapsulated bony mass (75 x 60 x 35 mm) with multiple blood-filled spaces. Histopathological diagnosis was an ABC originating in the left 4th rib. She has been doing well with no evidence of recurrence 12 months postoperatively.

Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal facet...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
