Primary central nervous system lymphoma (PCNSL) is an uncommon extranodal manifestation of non-Hodgkin's lymphoma with those presenting at the cerebellopontine angle (CPA) being rare presentations with limited reported cases in the literature. We report a 60-year old female presenting with PCNSL of the left CPA radiologically mimicking a trigeminal schwannoma with corresponding clinical signs. Imaging showed a left CPA lesion that was biopsied and confirmed as diffuse large B-cell lymphoma. Given its rarity, PCNSL should be considered in the differential diagnosis for all CPA tumours...

BACKGROUND: The use of intraoperative navigation during microscope cases can be limited when attention needs to be divided between the operative field and the navigation screens. Heads-up display (HUD), also referred to as augmented reality, permits visualization of navigation information during surgery workflow. OBJECTIVE: To detail our initial experience with HUD. METHODS: We retrospectively reviewed patients who underwent HUD-assisted surgery from April 2016 through April 2017...

We report a rare case of a primary central nervous system lymphoma (PCNSL) of the cerebellopontine angle (CPA) with infiltration into the pyramidal tract that initially presented as neurolymphomatosis (NL) of the acoustic nerve. A 60-year-old male suffered from right-side deafness and was referred to an otolaryngologist. Magnetic resonance imaging (MRI) showed fusiform enlargement of the right acoustic nerve with a hyperintense signal on a T2-weighted image (T2WI) and with gadolinium (Gd) enhancement, without an evidence of parenchymal CNS involvement...

In the central nervous system, cerebellopontine angle (CPA) lymphomas are rare; few cases have been reported. Lymphoplasmacytic lymphoma (LPL) in the CPA is rarer still, and often misdiagnosed as acoustic neuroma.We report a rare case of CPA LPL-a challenging diagnosis guided by clinical presentations, radiological signs, and postoperative pathological test.A 43-year-old woman presented with headaches. Her magnetic resonance imaging revealed an abnormal homogeneously enhancing mass in the left CPA. We present detailed analysis of her disease and review relevant literature...

Primary meningeal lymphomas are very rare and those derived from T cells are even more infrequent (less than 5% of primary central nervous system lymphomas). Cerebellopontine angle involvement in the primary T-cell lymphoma is exceptional. Clinical presentation depends on the type of lesions, and histological diagnosis is needed. We present a rare case of a 50-year-old woman who presented with clinical cerebellar syndrome with posterior opsoclonus-myoclonus syndrome. Necropsy evaluation revealed primary diffuse leptomeningeal non-Hodgkin's T-cell lymphoma...

An 80 year old man presented with a twelve month history of progressive multiple unilateral cranial nerve palsies. A gadolinium enhanced MRI scan of his head and neck was performed. This showed an extra-axial enhancing lesion, which enveloped the hemi-mandible at the level of the left inferior alveolar nerve, and a dumbbell shaped lesion within the cerebellopontine angle. An incisional biopsy was performed to gain a tissue diagnosis, which demonstrated a Non-Hodgkin's Lymphoma. The combination of signs, symptoms and radiological findings enabled a diagnosis of Garcin's Syndrome secondary to Non-Hodgkin's Lymphoma...

Current chemotherapeutic regimens have been used to successfully treat many children with acute lymphoblastic leukemia (ALL), but have resulted in an increased risk of late central nervous system tumors, most commonly meningioma, particularly in patients who have received cranial irradiation. We treated 3 young patients with World Health Organization grade II meningiomas who had previously received cranial irradiation for the treatment of childhood ALL: a cerebellopontine angle tumor in a 19-year-old woman, a petroclival tumor in a 28-year-old man, and a frontal parasagittal tumor in a 19-year-old woman...

Non-Hodgkin's lymphoma of the brainstem is a rare entity. Central Neurogenic Hyperventilation (CNH), an associated manifestation of this disease, is an even rarer event. We report a case of an immunocompetent individual who presented to us with tachypnea and facial nerve palsy. Neuroimaging showed a Cerebellopontine angle tumour which on histopathology showed feature consistent with a Non-Hodgkin's B-Cell Lymphoma. The patient went on to develop severe respiratory alkalosis with findings consistent with CNH...

Atypical teratoid rhabdoid tumor (AT/RT) is a rare entity. In the central nervous system, AT/RT generally arises from the posterior fossa of infants and behaves aggressively. AT/RT is reported to arise from the infratentorial region (63%) and other sites, such as the suprasellar region, cerebellopontine angle, and spinal cord. The pineal region is rare (6%) as a site of origin. Radiation-induced brain tumors are well known. In this report, we present a case of a pineal region tumor causing acute hydrocephalus that could be pathologically diagnosed as AT/RT following prophylactic cranial irradiation for acute lymphoblastic leukemia...

An abnormal vascular course of the superior cerebellar artery is often cited as the cause for trigeminal neuralgia. However, among patients with TN-like symptoms, 6% to 16% are variously reported to have intracranial tumours. Aneurysms, tumours, or other lesions may impinge or irritate the trigeminal nerve along its course. Uncommonly, an area of demyelination from multiple sclerosis may be the precipitant. We would like to present a series of unusual lesions, all of which initially presented with neuralgic-like symptoms and were refractory to treatment...

BACKGROUND: Intraoperative consultation for neurosurgical specimens can be difficult at times, despite the use of both frozen section and squash preparation. Various factors influence the diagnostic accuracy of these procedures. This study was conducted to evaluate reasons for discordant case results in neurosurgical intraoperative consultations and make a comparative analysis of these two commonly used methods to identify the possible pitfalls, errors, and limitations. MATERIALS AND METHODS: All the neurosurgical cases received in the Department of Pathology for intraoperative consultation over a period of 3 years were studied retrospectively...

REVIEW

A primary non-Hodgkin lymphoma (NHL) of the internal auditory canal or the cerebellopontine angle is an absolute rarity, even among the unusual lesions encountered there. Schwannomas or meningiomas account for approximately 90-95% of the tumors of the cerebellopontine angle and the internal auditory canal. Atypical symptoms, such as facial nerve palsy or rapid progression, require differential diagnostics to identify less frequent entities. However, clinical symptoms or the image morphology cannot confirm the diagnosis of a lymphoma...

Primary lymphoma of the cerebellopontine angle (CPA) is rare in the central nervous system. To our knowledge, there have only been 14 cases reported worldwide so far. Here, we report our findings in a 57-year-old man, who presented with bilateral sudden hearing loss followed by left facial palsy within 1 month. Radiologic study and magnetic resonance imaging showed a homogeneous enhancing mass, 1.6 x 0.5 x 1.1cm in size, in the left CPA cistern region with mild extension to the left internal auditory canal...

Computed tomography (CT) and magnetic resonance (MR) imaging reliably demonstrate typical features of vestibular schwannomas or meningiomas in the vast majority of mass lesions responsible for cerebellopontine angle (CPA) syndrome. However, a large variety of unusual lesions can also be encountered in the CPA. Covering the entire spectrum of lesions potentially found in the CPA, these articles explain the pertinent neuroimaging features that radiologists need to know to make clinically relevant diagnoses in these cases, including data from diffusion- and perfusion-weighted imaging or MR spectroscopy, when available...

Although approximately 30% of facial nerve schwannoma cases present with no facial palsy, a large facial nerve schwannoma extending to the middle and posterior cranial fossa quite rarely presents without facial palsy. The authors encountered two patients with large facial nerve schwannoma who presented with only hearing impairment and no facial palsy. The first patient was a 64-year-old woman who presented with right auditory impairment without facial palsy. MR images demonstrated a dumbbell-shaped tumor in the cerebellopontine angle...

This study attempted to evaluate the reliability of ultra-thin T2-weighted imaging with a constructive interference in steady state (CISS) sequence as a screening method for tumors in the cerebellopontine angle. A retrospective study of 200 CISS examinations was made by five investigators. The examinations were inspected on plain film supported by clinical information. The interobserver agreement in the detection of lesions was analyzed. Fourteen cases (50% of the contrast-enhancing lesions) were rated pathological by all five readers...

BACKGROUND: Tumors of the cerebello-pontine angle are most commonly schwannoma and meningioma. Primary central nervous system (CNS) lymphoma usually presents deep within the cerebral hemispheres, occasionally is found in the cerebellum, and rarely occurs in the cerebello-pontine angle. We report a rare case of primary CNS lymphoma involving the right cerebello-pontine angle and the middle cranial fossa mimicking a tentorial meningioma. METHODS: A 21-year-old woman presented with right sided hearing loss and a facial droop...

The authors describe a rare case of primary central nervous system (CNS) lymphoma presenting as bilateral cerebellopontine angle lesions. Imaging showed bilateral cerebellopontine angle lesions and also a small mass in right lateral ventricle and anterior third ventricle region. The right cerebellopontine angle mass was surgically excised and radio- and chemotherapy given for the remaining lesions. This is the second case reported in the world literature. The case is discussed and the literature is reviewed...
