Papillary Endothelial Hyperplasia

Abstract BACKGROUND AND IMPORTANCE: Papillary endothelial hyperplasia (PEH) is a rare form of exuberant reactive endothelial proliferation that can mimic neoplasm. We report the largest series of patients with histologically confirmed intracranial extravascular PEH developing in the field of previous treatment with stereotactic radiosurgery. CLINICAL PRESENTATION: We collected the clinical, radiological, surgical, and pathological findings from 4 patients in whom intracranial extravascular PEH developed after treatment with stereotactic radiosurgery. In all patients, the development of an enlarging hemorrhagic mass lesion at the site of previous radiotherapy on magnetic resonance imaging was radiographically suspicious for neoplasm and prompted biopsy or resection. All 4 patients elected to undergo biopsy or surgical resection. Histological examination of the biopsy and resection specimens in all patients demonstrated the classic features of PEH. CONCLUSION: The interval to the development of PEH ranged from 5 months to 6 years, 10 months. Clinical follow-up was available for 3 of the 4 patients. None of these 3 patients have demonstrated evidence of recurrence during a mean follow-up period of 22 months (range, 15–30 months). These patients share common radiological features, potentially allowing preoperative diagnosis and improved guidance of clinical management. These cases suggest a link between radiosurgery and the development of PEH. These findings also suggest that PEH should be considered in the differential diagnosis for patients treated with radiosurgery in whom a hemorrhagic mass lesion subsequently develops at or near the site of previous treatment. We think that complete surgical excision is the best treatment for intracranial PEH.

Galactocele is a rare breast condition in infants. Here, we report a 16-month-old boy who developed progressive left breast enlargement. Ultrasonography and magnetic resonance imaging revealed a 4 cm cystic lesion at left breast. Hormonal assay showed transient hyperprolactinaemia with no known cause identified. Subsequently, galactocele was confirmed on histopathological examination after complete surgical excision. No recurrence was observed on regular follow-up.

Solitary fibrous tumors (SFTs) are rare tumors that are mostly found arising from the pleura. SFT of the parotid gland is a rare tumor; only a few cases have been described in the literature. SFTs are benign in most cases. Clinically, SFTs usually manifest as well circumscribed, slow-growing, smooth, and painless masses. CT-Scan and MRI are the most sensitive imaging procedures used. The treatment of choice is complete surgical excision of the lesion. Since recurrence and metastasis can take place after several years, a lifelong clinical and imaging regular follow-up is compulsory. In this paper, we describe the diagnostic and therapeutic challenges of the up-to-now biggest parotid SFT. The clinical presentation, surgical management, and pathological and immunohistochemistry findings are described.

Abstract OBJECTIVE AND IMPORTANCE: Intramedullary melanotic schwannomas are very rare lesions; only four cases have been reported previously. We describe a patient with an intramedullary melanotic schwannoma that had a more aggressive course than those reported in the literature, and we review the theories regarding the cause of these lesions. CLINICAL PRESENTATION: A 35-year-old man presented with neck stiffness and paraesthesia extending down his right arm upon neck extension. A magnetic resonance imaging scan revealed an intramedullary lesion extending from C4 to C5. INTERVENTION: Gross total resection of the mass was performed, and pathological characteristics were consistent with a melanotic schwannoma. Two years after resection the tumor recurred, and the patient was treated with radiation therapy. The tumor progressed 2 years after radiotherapy, and at repeat resection, multiple pigmented foci were present on the surface of the spinal cord and dura consistent with metastatic seeding. CONCLUSION: In a patient with intramedullary melanotic schwannoma with an unusually aggressive course, careful follow-up may be essential.

Glial Heterotopia

Nasopharyngeal glial heterotopias is an extremely rare, nonhereditary, developmental malformation manifesting as a mass composed of mature neural tissue with no intracranial continuity. Glial heterotopia is a rare, non-neoplastic, extracranial midline malformation. Nasal glioma is the most frequently encountered entity among congenital nasal masses. Cases which are associated with intracranial extension are termed as encephalocele. It must be considered in the differential diagnosis of airway obstruction in neonates. Magnetic resonance imaging is mandatory to rule out intracranial extension. We report a rare case of heterotopic brain tissue in nasopharynx with no intracranial extension to attract attention to the diagnostic workup of nasopharyngeal obstruction in a neonate with respiratory distress. Clinical examination and radiological studies are diagnostic while early surgical excision and histopathological confirmation is the gold standard. This baby underwent complete intranasal endoscopic excision of mass on day 20 of life. The postoperative course was uneventful and the baby is growing well on follow-up. This case would be one of the few cases reported from India.

In each of seven ferrets ( Mustela putorius furo) with leiomyosarcoma, a single dermal mass was identified and biopsied. Each mass consisted of a well-demarcated but nonencapsulated proliferation of large spindle- to strap-shaped cells arranged in interwoven bundles. The cells resembled the smooth muscle cells of the adjacent arrector pili muscles, but with marked nuclear pleomorphism. Immunohistochemical staining for smooth muscle actin, desmin, and vimentin was positive and staining for myoglobin and cytokeratin was negative. Follow-up on three of the ferrets indicates that the prognosis is good following complete surgical excision.

Abstract OBJECTIVE Purely intradural clival chordomas are rare neoplasms, and only a few cases have been reported. The reported cases present features similar to ecchordosis physaliphora, which is a notochordal remnant. We describe these 2 entities and their differential diagnoses, clinical courses, and management. This is the first reported case to be treated using a neuroendoscopic technique. CLINICAL PRESENTATION A 60-year-old man presenting with memory loss underwent magnetic resonance imaging, which revealed an intradural retroclival mass without bone involvement. INTERVENTION The patient underwent an endoscopic transsphenoidal-transclival procedure with subtotal removal of the tumor. Histological findings confirmed the diagnosis of a chordoma. CONCLUSION Even if some parameters exist for a differential diagnosis, ecchordosis physaliphora and intradural chordoma may represent different aspects of the spectrum of the same pathology. Intradural clival chordomas have a better prognosis with respect to classic chordomas. Therefore, in subtotal removal such as that performed in our case, postoperative radiation therapy should be performed only if a regrowth of the remnant is seen during neuroradiological follow-up.

Attention To Detail

Ductography or galactography is a technique used in the diagnostic workup of unilateral, single duct, spontaneous, and bloody or clear nipple discharge. Mammographic imaging with magnification may reveal the source of the discharge. The technique is challenging, yet it can be mastered with attention to detail, a well thought-out protocol, and practice. Imaging findings can be non-specific, yet may guide biopsy or surgical excision. Now with the wide use of breast magnetic resonance imaging (MRI), which has been shown to be more sensitive for lesion detection, ductography is used less frequently. This chapter, appearing in the section on interventions and surgical changes, reviews the indications, procedure protocols, and pitfalls, as well as the management and imaging follow-up for ductography or galactography.

AbstractOrbital schwannomas are rare neoplasms of the orbit. The presenting symptoms are often nonspecific. Classic imaging characteristics seen on magnetic resonance imaging (MRI) and orbital ultrasound can be useful to help aid in the diagnosis of orbital schwannoma. When diagnosed, the goal of treatment is complete surgical excision. The location of the tumor within the orbit dictates which surgical approach would provide the best exposure. When complete excision is achieved, recurrence rates are very low.This article addresses the etiology, patient population, presentation, natural history, and differential diagnosis of orbital schwannomas. Imaging characteristics and histopathologic subtypes are reviewed. Treatment goals, approaches, and specialties involved in the management of these patients is discussed. Finally, a representative case is presented.

Abstract OBJECTIVE We report the youngest known case of a prepontine intradural chordoma. These tumors are exceedingly rare. Unlike their more common extradural counterparts, no recurrence of an intradural chordoma has been reported. CLINICAL PRESENTATION A 9-year-old boy underwent diagnostic imaging for evaluation of headaches. Although neurologically intact, a magnetic resonance imaging scan revealed a large prepontine mass with focal enhancement. INTERVENTION Endoscopic-assisted gross total resection was attained with staged bilateral retrosigmoid approaches. There were no additional adjuvant therapies. At the time of the 1-year follow-up evaluation, the patient had no recurrence. CONCLUSION By using an endoscopic-assisted procedure, we achieved complete resection of an intradural chordoma offering a potential for surgical cure. Resection is particularly advantageous because it spares the young child the need for radiation treatment. Close follow-up is warranted because we postulate that this tumor exists in a biological continuum between benign notochordal hamartomatous remnants and typical invasive chordomas.
