“…The technology of medical imaging, such as digital cerebral angiography and three-dimensional (3D) mapping of brain vessels, has achieved relevant advances in interventional neuroradiology. A number of recent publications in Brazil highlight the importance of neuroradiology for diagnosis and treatment of several diseases (1)(2)(3)(4)(5)(6)(7)(8)(9)(10) .…”

Evaluation of occupational and patient dose in cerebral angiography procedures

Objective: The present study was aimed at estimating the doses received by physicians and patients during cerebral angiography procedures in a public hospital of Recife, PE, Brazil. Materials and Methods: The study sample included 158 adult patients, and during the procedures the following parameters were evaluated: exposure parameters (kV, mAs), number of acquired images, reference air kerma value (K a,r) and air kerma-area product (P KA). Additionally, the physicians involved in the procedures were evaluated as for absorbed dose in the eyes, thyroid, chest, hands and feet. Results: The results demonstrated that the doses to the patients' eyes region were relatively close to the threshold for cataract occurrence. As regards the physicians, the average effective dose was 2.6 µSv, and the highest effective dose recorded was 16 µSv. Conclusion: Depending on the number of procedures, the doses received by the physicians may exceed the annual dose limit for the crystalline lenses (20 mSv) established by national and international standards. It is important to note that the high doses received by the physicians are due to the lack of radiation protection equipment and accessories, such as leaded curtains, screens and protective goggles.

“…A cerebelite aguda é uma doença rara, correspondendo a uma forma de encefalomielite inflamatória localizada, resultante do atingimento infecioso ou inflamatório do cerebelo. 1 Trata-se de uma entidade com espetro clínico variável, onde se incluem casos com sintomas autolimitados até apresentações fulminantes. 2 Anteriormente, os termos "cerebelite aguda" e "ataxia cerebelosa aguda" eram considerados sinónimos, mas atualmente considera-se que a evidência de inflamação predominantemente cerebelosa na ressonância magnética crânio-encefálica (RM-CE) é necessária para o diagnóstico de cerebelite aguda.…”

“…Caracteriza-se pela presença de ataxia da marcha e apendicular, disartria, alterações da oculomotricidade, tremor, alteração do estado de consciência, em associação variável a sintomas sistémicos, como febre, náuseas e vómitos. [1][2][3] A raridade e o espetro clínico variável da cerebelite condicionam o consenso em torno de uma abordagem individualizada. 2 Globalmente, aceita--se que o tratamento inclua medidas sintomáticas, nos casos ligeiros, ou uma intervenção cirúrgica para des-compressão da fossa posterior, em situações graves.…”

Acute cerebellitis is a rare disease resulting from dysfunction of the cerebellum or its connections, with infectious or inflammatory causes, varied clinical manifestations, and evidence of predominantly cerebellar inflammation on magnetic resonance imaging (MRI). It belongs to the spectrum of acute post-infectious cerebellar ataxia, a self-limited disease whose therapeutic approach is individualized. Three clinical cases of cerebellar ataxia in pediatric age are described. In case 1, there is a post-infectious context associated with Epstein-Barr virus. In case 2, there is a possible Mycoplasma pneumoniae post-infectious context, with MRI revealing cerebellar inflammation. Steroids were used in both cases. Case 3 presents severe cerebellar post-infection symptoms associated with varicella zoster virus, and human immunoglobulin was given. Evolution was favorable in all. These cases demonstrate the variable spectrum of post-infectious cerebellar ataxia and the different therapeutic options used, depending on the clinical presentation and individual characteristics of affected children.

“…The differential diagnosis mainly includes hemangioblastomas, pilocytic astrocytomas, medulloblastomas, and ependymomas. 3 Likewise, infections, such as cerebellitis 4 and cerebellar infarction, 5 may also present as space-occupying lesions of the cerebellum.…”

Posterior Fossa Intra-Axial Lesion: There Are Pathologies Beyond Metastases

et al. 2022

Cerebellar metastases represent the most common lesion requiring surgical treatment in the daily neurosurgical praxis. We report a rare case with Lhermitte–Duclos disease presenting to the neurosurgical outpatient department and describe our diagnostic and treatment challenges. A 57-year-old man presented with transient cerebellar manifestations, including walking difficulties, dizziness, and a persistent occipital headache. The magnetic resonance imaging demonstrated a high-intensity lesion in the right cerebellar hemisphere on T2-weighted images. We initially considered surgery to establish a histopathological diagnosis. However, the magnetic resonance spectroscopy was compatible with a dysplastic gangliocytoma of the cerebellum. Therefore, we preferred a more conservative approach. Posterior fossa contrast-enhancing lesions are much more than metastases. The role of advanced magnetic resonance in avoiding unnecessary surgical interventions is priceless.
