“…16) Only four cases of interhemispheric lipoma connected to subcutaneous lipoma via a bone defect in the anterior fontanel 2,5,13) and midline parietal bone 1) have been reported in infants. A previous case of cerebellopontine angle lipoma extending to the extracranial space involved a defect in the petrous ridge, 7) and a lipomatous stalk was identified between an interhemispheric lipoma and subcutaneous tissue in a 9-week-old boy. 5) In our case, a lipomatous stalk connected the intra-and extracranial parts of the tumor via a bone defect in the midline parietal region.…”

A 66-year-old man presented with complaints of numbness for the past 5 years and progressive motor weakness of the right leg for the previous 2 months. Magnetic resonance imaging revealed large intraand extracranial tumors in the frontoparietal region. Physical examination suggested the extracranial lesion was a subcutaneous lipoma, which had been partially resected 60 years before, connected to the intracranial lesion via a defect of the skull. Gross total removal of the tumors was performed. Histological examination showed the intracranial lesion was epidermoid tumor, and connected to the extracranial lipoma by a lipoma bridge. The symptoms improved remarkably following surgery. This case of intracranial epidermoid tumor associated with intra-extracranial lipoma indicates that implantation of skin tissue in childhood carries the risk of epidermoid tumor even after several decades. Neuroimaging screening is recommended to detect the development of any intracranial components.

“…Due to the rare incidence of these tumors of the cerebellopontine angle, experience in therapeutic management is limited, and the resection is indicated, by several authors, only in symptomatic cases refractory to targeted medical therapies aimed to alleviate intractable cranial neuropathies or reduce compression on the brain stem. 15 Most of the CPA lipomas are managed conservatively. 16 However, when the lesion reaches a considerable size and involves a critical neurovascular structure, causing symptoms, the surgical approach is recommended to pursue the decompression on neural structures.…”

Intracranial lipomas are rare benign tumors considered exceptional when localized in the cerebellopontine angle (CPA), with an incidence of 0.1% of the total number of expansive processes located in this area. We present a case of the sudden death of a 26-year-old young woman in which an unencapsulated neoformation of 0.8 cm was documented at the right cerebellopontine angle and was histologically characterized as intracranial lipoma. The cause of death was then identified as a cardiocirculatory failure secondary to supratentorial (uncal right) herniation caused by the lipoma of the pontocerebellar angle with high-grade diffuse cerebral edema.

“…Most CPA lipomas involve cranial nerves VII and VIII along with the anterior inferior cerebellar artery (AICA) [ 8 , 11 ]. However, there have been cases reported with the involvement of cranial nerves V, IX, X, and XI and the anterior circulation vasculature [ 13 - 14 ].…”

“…This is because CPA lipoma symptomatology resembles that of other CPA tumors, including vestibular schwannomas, meningiomas, and so on. Despite their rarity, CPA lipomas should be included in the differential diagnosis of patients with cochleovestibular signs (sensorineural hearing loss, tinnitus, and vertigo), facial nerve signs (hemifacial spasms and facial motor impairment), and trigeminal nerve signs (sensory loss and trigeminal neuralgia) [ 5 , 7 , 14 ]. The most common signs of CPA lipomas are hearing loss, tinnitus, vertigo, facial symptoms (facial and trigeminal nerve signs), and headaches [ 11 ].…”

Diagnostic Dilemma: Cerebellopontine Angle Lipoma Versus Dermoid Cyst

Both lipomas and dermoid cysts of the cerebellopontine angle are rare tumors. These tumors differ in their embryological origin but share similar features on imaging. Both of these congenital lesions can be found in the cerebellopontine angle (CPA), and symptomatic clinical presentation is dictated by the location of the lesion. This paper demonstrates a unique case in which a CPA lipoma was misidentified as a dermoid cyst, leading to surgical intervention. Further, the paper provides a literature review of CPA lipomas and dermoid cysts to aid readers in further differentiating between these two unique tumors.
