Case 12
History:
45 year old female with persistent cough and increasing dyspnea.
Findings:
Chest CT showing a round, well defined soft tissue lesion involving and narrowing the right main brochus.
Diagnosis:
Intra bronchial schwannoma
Discussion:
The incidence of primary neurogenic tumor of the lungs to be 0 to 2%. Likely originating from schwann cell and predominantly associated with neurofibromatosis. The diagnosis of intratracheal tumors is usually made by endoscopy. However, although the findings are not specific, CT scanning and magnetic resonance imaging (MRI) are increasingly used to delineate tumor size and extension as well as associated parencymal changes.
