Middle ear capillary haemangioma causing vestibulocochlear symptoms: a case report.

PROBLEM: A 58-year-old man presented with transient vertigo and pulsatile tinnitus.

METHODS

High-resolution computed tomography, magnetic resonance imaging, excision, and subsequent immunohistochemical assays were performed.

RESULTS

Imaging showed a soft tissue mass in the epitympanum and mastoid with bone erosion of the tegmen tympani and a dural tail sign, suggesting meningioma. Subsequently, because of signs of clinical progression, a canal-wall-up attico-antromastoidectomy was performed, with near-complete removal of a granulomatous, ossifying, haemorrhagic mass.

CONCLUSIONS

Radiological imaging was critical in determining the extent of the mass and excluding other pathologies. Due to the atypical clinical and radiological signs, the final diagnosis of capillary haemangioma of the middle ear and temporal bone was made only after surgical resection and histopathological examination with immunohistochemistry, which excluded meningioma. The contiguous occurrence of cutaneous capillary haemangioma of the lateral face and neck was an important clue to the diagnosis.
