First Case

Two cases of inflammatory myofibroblastic tumor (IMT) of the bladder are reported here. Both patients were male and presented with macroscopic hematuria; in the first case terminal hematuria was associated with irritative voiding symptoms. The second case was a smoker with hematuria unresponsive to medical treatment and anemia. Clinical presentation, pathological features, treatment, and prognosis are discussed. Due to rarity of this pathological condition, there are no guidelines concerning treatment and follow-up. We present our follow-up scheme and highlight the use of laparoscopic partial cystectomy as a successful treatment approach.

Laser Excision

Inflammatory myofibroblastic tumor (IMT) is a benign neoplasm of intermediate biologic potential. It rarely occurs in the larynx, and it has not been previously reported in the epiglottis. We treated a 66-year-old woman who presented with progressive dysphonia and a mass on her suprahyoid epiglottis. The tumor was completely excised with a CO2 laser; no adjuvant therapy was administered. Histopathology revealed that the mass was an IMT. No evidence of recurrence was noted after 6 months of follow-up. We present what we believe is the first case of an epiglottic IMT to be reported in the literature, and we propose CO2 laser excision without adjuvant therapy as an acceptable treatment.

The Authors report a case of vesical hemangioma; it was typical for site and clinical presentation whereas the age of onset and gross appearance were atypical. A TUR biopsy was performed without complications, but did not confirm diagnosis. A partial cystectomy was performed. A one-year follow-up, negative for recurrence, confirmed this procedure as the definitive treatment of choice.

Abstract OBJECTIVE AND IMPORTANCE The complex regional anatomic features surrounding the sella turcica make the differential diagnosis of intrasellar and parasellar lesions complicated. Sellar and parasellar schwannomas are rare. With the exclusion of parasellar schwannomas arising from cranial nerves within the cavernous sinus and extending into the sella, there have been only two reported cases of true intrasellar schwannomas. CLINICAL PRESENTATION We describe the clinical, radiological, and pathological features of two cases in which the histopathological diagnosis of schwannoma was confirmed with immunohistochemical analyses and/or electron microscopy. INTERVENTION The two cases were grossly resected via a transsphenoidal approach. Follow-up monitoring revealed no evidence of recurrence. CONCLUSION Schwannomas may atypically occur in the sellar region, in which they demonstrate the typical light microscopic, immunohistochemical, and ultrastructural features observed in the peripheral nervous system. New and existing hypotheses regarding the histopathogenesis of intrasellar and parasellar schwannomas are presented.

Initial Description

Angiocentric glioma is a rare tumor that was recognized by the WHO Classification of Tumours of the Central Nervous System as a distinct clinicopathological entity in 2007. Since this initial description, the vast majority of cases of angiocentric glioma reported in the literature have involved tumors of the cerebral hemispheres. To date, only 1 case of angiocentric glioma arising from the posterior midbrain has been reported. The authors present the cases of 2 pediatric patients who were found to have brainstem angiocentric gliomas. The clinical course, radiological and pathological features, treatment, and follow-up are described. The first case is one of a 5-year-old girl who presented with double vision, headache, and nausea and was found to have a midbrain lesion with pathological features consistent with angiocentric glioma. She was treated with resection and endoscopic third ventriculostomy (ETV), followed by close observation and serial neuroimaging. The second case is one of a 6-year-old boy who presented with progressive mouth drooping and problems with balance. He was found to have a pontine lesion with pathological features consistent with angiocentric glioma. This patient was treated with ETV, followed by close observation and serial neuroimaging. This report includes 6 and 1.5 years of follow-up of the patients, respectively. While there are limited data regarding the prognosis or long-term management of patients with brainstem angiocentric gliomas, the cases described in this report suggest an indolent course for this tumor, similar to the course of angiocentric gliomas located in the cerebral hemispheres.

ABSTRACT BACKGROUND AND IMPORTANCE: Basilar trunk perforator (BTP) aneurysms are rare lesions that pose significant challenges to microsurgical clipping and endovascular coiling. We present the intriguing case of a ruptured BTP aneurysm that was successfully treated with the Pipeline Embolization Device (PED). CLINICAL PRESENTATION: An elderly woman presenting with subarachnoid hemorrhage was found to have a 1.5-mm aneurysm arising from the proximal portion of a thin midbasilar perforator. The decision was made to treat this aneurysm with flow diversion in an attempt to preserve the patency of the perforator and to avoid the hazards associated with parent vessel trapping. A 3 × 12-mm PED was successfully deployed in the basilar trunk across the neck of the aneurysm, causing stasis in the aneurysm, with continuous flow through the parent vessel. The procedure and postoperative course were uneventful. A follow-up angiogram 2 weeks later showed complete disappearance of the aneurysm with preservation of the patency of the perforator. At the 6-month follow-up, the patient was asymptomatic and remained neurologically intact. CONCLUSION: We present the first case of a BTP aneurysm treated with the PED. The aneurysm was successfully occluded, and the patency of the feeding vessel was preserved. In light of the limitations of coiling and the hazards associated with microsurgery and parent vessel trapping, the PED may be a valuable option for BTP aneurysms.

Abstract BACKGROUND AND IMPORTANCE Deep brain stimulation of the posteromedial hypothalamus (PMH DBS) appears to be an effective treatment for drug-resistant aggressiveness. Weaver syndrome (WS) is a rare genetic disorder in which patients develop some degree of intellectual disability and rarely severe behavioral alterations that may benefit from this procedure. CLINICAL PRESENTATION We present the case of a 26-yr-old man diagnosed with WS presenting with uncontrollable self and heteroaggressiveness and disruptive behavior refractory to pharmacological treatment and under severe physical and mechanical restraining measures. The patient was successfully treated with bilateral PMH DBS resulting in affective improvement, greater tolerance for signs of affection, regularization in his sleep pattern and appetite disturbances at 12-mo follow-up. A detailed description and video of the procedure are presented, and a review of the clinical characteristics of WS and the utility and benefits of PMH DBS for refractory aggressiveness are reviewed. CONCLUSION To our knowledge, this is the first case of refractory aggressiveness described in WS as well as the first patient with WS successfully treated with PMH DBS.

Objective: To report the first case in the literature of a primary large-cell undifferentiated carcinoma (LCUC) of the ureter with a very aggressive behavior and dismal prognosis. Clinical Presentation and Intervention: A 60-year-old woman with a history of intermittent macroscopic hematuria and mild to moderate right flank pain was admitted to the Department of Urology. Tissue biopsies and cytological samples were taken. Pathologic examination was consistent with LCUC. Conclusion: LCUC of the ureter is an aggressive tumor with a high proliferation index. Patients might be diagnosed at an advanced stage. LCUC must be considered in the differential diagnosis of urinary tract pathologies.

AIMS: To report two cases of spondylocostal dysostosis, describing their clinical presentation and evolution. CASES DESCRIPTION: Two non-related cases of spondylocostal dysostosis are reported. The first case consists of an 11 years old boy, and the second case is a girl with four years of age. In both cases, short neck and trunk, scoliosis, rib and sacrococcygeal anomalies were evident at birth. The clinical diagnosis of spondylocostal dysostosis was confirmed by the finding of a mutation in both alleles of the DLL3 gene. Their clinical evolution was satisfactory, with no respiratory complications until this report. CONCLUSIONS: The spondylocostal dysostosis are a group of disorders characterized by severe skeletal malformations, with rib anomalies such as broadening, bifurcation and no symmetric fusion. Although it is known to be a rare situation, its exact incidence or prevalence is not well established. An early diagnosis and appropriate management are extremely important for adequate family counseling and follow-up.

Abstract OBJECTIVE AND IMPORTANCE Malignant fibrous histiocytoma in the central nervous system is uncommon. Fewer than 70 cases have been documented and, to the best of our knowledge, this is the first case arising from the cerebellum. CLINICAL PRESENTATION A 44-year-old woman presented with headaches, vomiting, and dizziness. A neurological examination revealed right cerebellar syndrome. Brain computed tomographic scans revealed an isodense tumor in the right cerebellar hemisphere. The breast ultrasonographic, bone scintigraphic, and thoracoabdominal computed tomographic findings were normal. INTERVENTION The patient was surgically treated. The tumor recurred 1.5 months later, demonstrating hemorrhagic characteristics on brain computed tomographic scans. The patient underwent a second operation, followed by radiotherapy. CONCLUSION Malignant fibrous histiocytoma is still a controversial entity, and the lack of specific criteria means that it must be diagnosed via the process of elimination. With currently available therapy, our review can provide only a very poor prognosis. The median survival time was 27 months. In attempts to develop better therapeutic strategies, total excision and radiotherapy seem to represent the best treatment approach.

OBJECTIVEFew studies describe long-term functional outcomes of pediatric patients who have undergone lumbar microdiscectomy (LMD) because of the rarity of pediatric disc herniation and the short follow-up periods. The authors analyzed risk factors, clinical presentation, complications, and functional outcomes of a single-institution series of LMD patients over a 19-year period.METHODSA retrospective case series was conducted of pediatric LMD patients at a large pediatric academic hospital from 1998 to 2017. The authors examined premorbid risk factors, clinical presentation, physical examination findings, type and duration of conservative management, indications for surgical intervention, complications, and postoperative outcomes.RESULTSOver the 19-year study period, 199 patients underwent LMD at the authors’ institution. The mean age at presentation was 16.0 years (range 12–18 years), and 55.8% were female. Of these patients, 70.9% participated in competitive sports, and among those who did not play sports, 65.0% had a body mass index greater than 25 kg/m2. Prior to surgery, conservative management had failed in 98.0% of the patients. Only 3 patients (1.5%) presented with cauda equina syndrome requiring emergent microdiscectomy. Complications included 4 cases of postoperative CSF leak (2.0%), 1 case of a noted intraoperative CSF leak, and 3 cases of wound infection (1.5%). At the first postoperative follow-up appointment, minimal or no pain was reported by 93.3% of patients. The mean time to return to sports was 9.8 weeks. During a mean follow-up duration of 8.2 years, 72.9% of patients did not present again after routine postoperative appointments. The total risk of reoperation was a rate of 7.5% (3.5% of patients underwent reoperation for the same level; 4.5% underwent adjacent-level decompression, and one patient [0.5%] ultimately underwent a fusion).CONCLUSIONSMicrodiscectomy is a safe and effective treatment for long-term relief of pain and return to daily activities among pediatric patients with symptomatic lumbar disc disease in whom conservative management has failed.
