Unilateral hearing loss due to a rhabdomyoma in a six-year-old child

Intracranial Rhabdomyoma: Case Report and Review of the Literature

A 24-year-old male presented with eight months of increasingly severe frontal headaches, decreased right facial sensation, and periodic vertigo. Magnetic resonance imaging demonstrated a heterogeneously contrast-enhancing mass involving and expanding the right foramen ovale.  A biopsy of the lesion was performed, and the final pathologic diagnosis revealed a neoplastic rhabdomyoma. To date, only five cases of intracranial rhabdomyoma have been reported, and a rhabdomyoma involving the trigeminal nerve has never been described in an adult. This manuscript reviews the available literature and highlights the clinical, imaging, pathologic characteristics, and surgical management of these exceedingly rare lesions.

A 68-year old man with a cerebellopontine angle tumor

We report on a 68-year-old male with a cerebellopontine angle tumor manifesting at the 8th cranial nerve and presenting histopathological features of a rhabdomyoma. A literature review revealed four reports of intracranial nerve rhabdomyoma, all of adult type and including one manifestation at the vestibular nerve. We present the first case of a fetal type extracardiac rhabdomyoma manifesting at a cranial nerve. Although rare, rhabdomyomas must be considered in the differential diagnosis of vestibular schwannomas.

Pleomorphic xanthoastrocytoma of the cerebellopontine angle in a child

CASE REPORT

The case of a 6-year-old girl with a pleomorphic xanthoastrocytoma (PXA) in the left cerebellopontine angle (CPA) is reported. The clinical, radiological, and histopathological findings are presented.

DISCUSSION

To our knowledge, the presence of PXA in the CPA has not previously been reported. The rare infratentorial locations of PXA (frequently seen in association with ganglioglioma) are reviewed, as well as the other infrequent locations of this tumor. This report adds to the list of differential diagnoses of CPA tumors in children.

Multifocal adult rhabdomyoma of the head and neck: a case report and literature review

Adult extracardiac rhabdomyomas are rare benign skeletal muscle tumors that most commonly present in the head and neck region. Only a few multifocal cases have been described to date in the world literature. We hereby present an additional multifocal case, the 14th worldwide, and review the literature.
