“…Data are scarce, and there is no guideline on which surgical strategy to opt for. However, previous case reports have shown seizure-free after radical surgical management of these lesions (Table 1) [1,[10][11][12][13][14][15]. Gross total resection should be attempted whenever possible.…”

Epidermoid cysts represent roughly 1% of all intracranial tumors. They are frequently located in the cerebellopontine angle but rarely extend to the supratentorial brain. Epilepsy is an extremely uncommon manifestation of this neoplasm. We suggest the surgical management of a 35-year-old male who presented with a six-month history of intractable temporal lobe epilepsy. His seizures were characterized by a focal onset in the form of déjà vu experiences, followed by a secondarily generalized tonic-clonic seizure. Imaging revealed a heterogeneous cystic mass in the right cerebellopontine angle, extending supratentorially causing a mass effect on the mesial temporal region. Gross total resection was achieved through a combined subtemporal-retrosigmoid approach. Histopathology revealed an epidermoid cyst. The patient was entirely seizure-free at the three-month follow-up. Epidermoid cysts may present with epileptic seizures. Seizure freedom can be achieved with surgical management in most cases. The patient's symptoms, imaging findings, and epileptogenic focus must be considered to select the appropriate surgical strategy.

An unusual presentation of an epidermoid brain tumour: a tale of two specialties

A 33-year-old right-handed lady was referred to the psychiatry and neurology services by her general practitioner. Previously, she was under psychiatric care for bipolar affective disorder. Recently, her mood had deteriorated prompting the re-referral to the psychiatrists. In addition she had strange attacks. These strange attacks seemed to her like 'sensory overload' or that the 'brain just stops'. Other sensations throughout the attacks included feeling like she is in a 'fish bowl' and surrounding sights and sounds were distorted. She could not speak. After the attack she was hot and flustered, suffered memory loss and was tearful. Both the psychiatrist and the neurologist considered the possibility of these attacks being psychiatric in aetiology. However, the alternative possibility of a coexistence to epilepsy and depression was investigated and MRI demonstrated an epidermoid tumour with the supratentorial portion displacing the left temporal lobe.

Mesial temporal lobe epidermoid tumour compressing the hippocampal formation caused refractory temporal lobe epilepsy

Abstract: The authors report an unusual case of intradural epidermoid tumour in a 19-year-old girl presenting with refractory complex partial seizures including auditory hallucinations, and memory dysfunction. A complete resection was carried out sparing the hippocampus resulting in seizure freedom.
