Primary diaphyseal tuberculosis of the tibia

Area of Science:

• Orthopedics
• Infectious Diseases
• Radiology

Background:

• Tuberculous osteomyelitis typically affects joints, but diaphyseal involvement without articular signs is exceptionally rare.
• Nonspecific symptoms like pain and swelling often delay diagnosis, leading to potential misdiagnosis with other bone conditions.

Observation:

• A 28-year-old man presented with symptoms suggestive of tibial osteomyelitis.

Findings:

• The case involved primary diaphyseal tuberculosis of the left tibia, a rare presentation.
• Radiographic findings mimicked other conditions such as pyogenic osteomyelitis, Brodie's abscess, tumors, or granulomatous lesions.
• Curettage and histopathological examination were crucial for accurate diagnosis.

Implications:

• This case highlights the importance of considering tuberculosis in the differential diagnosis of diaphyseal osteomyelitis, even without joint involvement.
• Early diagnosis through histopathology and appropriate management, including surgical curettage, can lead to successful outcomes.
• Further research into the diagnostic challenges and management strategies for rare forms of osteomyelitis is warranted.
