Six patients with cranial polyneuropathies due to invasion of nasopharyngeal malignant tumors were reported.
The first patient showed Pseudo-GRADENIGO's syndrome with involvement of left V th and VI th nerve by invasion of anaplastic carcinoma of the nasopharynx.
The second and third patients with nasopharyngeal carcinoma showed Collet-Sicard's syndrome due to left cranial neuropathies of IX, X, XI, XII.
In the 4 th case, the combined syndromes composed from Pseudo-Gradenigo's syndrome and Collet-Sicard's syndrome were observed.
In the 5 th case, who had very curious symptoms of cranial nerves, V, VI, VII in both sides and IX in right side, it was revealed that such neuropathy depended on the cerebrovascular diseases from the findings of autopsy.
The 6 th patient with malignant mesenchymal tumor of nasopharynx suffered in the superior orbital fissure syndrome with involvement of left cranial nerves II, III, IV, V, VI.
On the clinical results of these cases, the relationship between the cranial neuropathy and nasopharyngeal malignancy were discussed in view of neuroanatomy.
