Schistosomiasis mansoni presenting as a cerebellar tumor: case report

The Manson's schistosomiasis tumoral form rarely affects the brain. There are only 12 cases prior related with a mean age of 25 years and a male predominance. We describe a 16-year-old Brazilian Northeastern boy with a cerebellar mass lesion. The radiological aspect was considered compatible with glioma and a gross total resection was performed. Microscopic examination disclosed intraparenchymal granulomas surrounding Schistosoma mansoni eggs. The case is compared with the literature findings and some peculiar aspects of this trematode infection are reviewed.

Introduction. Meningiomas are slow growing, extra-axial lesions, and can be neurologically silent for a long time and present only with depression. Case Outline. A 65-year-old woman developed major depression and was treated with antidepressants for two years. Depression failed to respond to drug treatment and there was no improvement. Two months before admission to hospital, due to the onset of epilepsy attack the patient underwent reinvestigation, and a large temporal convexity meningioma, which corresponded in position to the original electroencephalography focus, was diagnosed using the computer topography of the brain. The patient underwent osteoplastic craniotomy, and a left fronto-temporal convexity meningioma of 5 cm in diameter was completely removed with its attachment to the dura. Histological examination confirmed a fibroblastic meningioma. Conclusion. Total resection of convexity meningioma and decompression of the brain tissue in the region of limbic pathways that are involved, may contribute to a complete remission of depression symptoms. This case also illustrates the need for a prompt neuroimaging of the brain when patients present any atypical psychiatric symptoms, with late onset (>50 years old) of the first depressive episode or fast changes of the mental state.

AbstractMeningitis or meningoencephalitis are the most common presentations of Koch bacilli infection on the central nervous system (CNS), especially in immunosuppressed patients, in whom the bacilli normally reaches the meninges and the cerebral parenchyma.. A least common pathological presentation is the tumoral growth pattern disease known as tuberculoma. This pathological entity is more common in the cerebral hemispheres and is rarely located in the brainstem. The present case report describes a case of a 55-year-old patient under regular antiretroviral therapy who was hospitalized with signs of brainstem and cerebellar disturbances. Computed tomography (CT) and magnetic resonance imaging (MRI) of the brain showed an exophytic lesion in the dorsal region of the pons. The patient underwent total resection of the lesion and the histopathologic analysis was consistent with a tuberculoma.

Abstract Objective: To present an alternative technique of endoscope-controlled microneurosurgery for the treatment of middle fossa epidermoid cysts. Methods: The three operations described were performed through an approximately 2-cm diameter temporal craniotomy after a straight skin incision was made. Resection was then performed under the magnification of a 30-degree rigid endoscope, which mandated the use of exclusively conventional microsurgical instruments. Results: Total resection was accomplished in all three patients with large middle fossa epidermoid cysts through a small temporal corticectomy, without damage to neurovascular structures. Conclusion: This procedure allowed the association of a smaller craniotomy, better cosmetic results, and minor retraction of the brain to wide resection of the tumor and satisfactory functional outcomes.

Phosphaturic mesenchymal tumor (mixed connective tissue variant) (PMT-MCT) are tumors that may cause tumor-induced osteomalacia and rarely appear intracranially. The authors describe the case of an 8-year-old girl who was found to have PMT-MCT with involvement of the cerebellar hemisphere and a small tumor pedicle breaching the dura mater and involving the skull. This was removed surgically in gross-total fashion without further complication. Histologically the tumor was confirmed to be a PMT-MCT. There was no evidence of tumor-induced osteomalacia. At the 42-month follow-up, the patient is doing well, has no abnormalities, and is free of recurrence. PMT-MCTs are rare tumors that may involve the brain parenchyma. A gross-total resection may be effective to cure these lesions.

Moyamoya is an uncommon disease that presents with stenoocclusion of the major vasculature at the base of the brain and associated collateral vessel formation. Many pediatric patients with moyamoya present with transient ischemic attacks or complete occlusions. The authors report the case of a 9-year-old girl who presented with posterior fossa hemorrhage and was treated with an emergency suboccipital craniotomy for evacuation. After emergency surgery, an angiogram was performed, and the patient was diagnosed with moyamoya disease. Six months later, the patient was treated for moyamoya using direct and indirect revascularization; after surgery there was excellent vascularization in both regions of the bypass and no further progression of moyamoya changes. This case illustrates a rare example of intracerebral hemorrhage associated with moyamoya changes in the posterior vascularization in a pediatric patient and subsequent use of direct and indirect revascularization to reduce the risk of future hemorrhage and moyamoya progression.

Abstract Background Heterotopic ossification (HO) is the formation of osseous tissue outside the skeleton. HO in malignant tumors of the digestive tract is extremely rare, as is ossification in metastatic lesions from HO-negative digestive tract tumors. Regarding the pathogenesis of HO, two theories have been proposed. The first is that the osteoblastic metaplasia of tumor cells (driven by the epithelial-mesenchymal transition, EMT) results in HO, and the second is that factors secreted by cancer cells lead to the metaplasia of stromal pluripotent cells into osteoblasts. However, the osteogenic mechanisms remain unclear. Case presentation An 83-year-old Japanese woman underwent low anterior rectal resection for rectal cancer before presentation at our institution, in June 2018. The final diagnosis was stage IIB rectal adenocarcinoma (T4aN0M0). Histological examination did not reveal HO in the primary tumor. Thirteen months after the operation, a solitary metastatic lesion in the brain 20 mm in size and a solitary metastatic lesion in a right axillary lymph node 20 mm in size were diagnosed. The patient was treated with gamma-knife therapy for the brain metastasis. One month later, she was referred to our institution. She underwent lymph node resection. Histological examination revealed that most portions of the affected lymph node were occupied by metastatic tumor cells and that central necrosis and four small ossified lesions without an osteoblast-like cell rim were present in the peripheral region. Immunohistochemical analysis showed tumor cells positive for BMP-2, osteonectin, osteocalcin, AE1/AE3, TGF-β1, Gli2, Smad2/3, and CDX2 and negative for nestin, CD56, and CK7. Conclusion This is the first English case report of HO in a metachronous metastatic lymph node after the curative resection of HO-negative rectal cancer. Unlike HO lesions in past reports, the HO lesion did not show peripheral osteoblast-like cells, and the immunohistochemical findings indicated that the present case resulted from the EMT.
