BACKGROUND Osteomas of the paranasal sinuses are benign, slow-growing bone tumors that can cause a variety of clinical features depending on their size and location. Most osteomas are asymptomatic and located in the frontal sinus. In rare cases, they may grow to extend into the cranial or orbital cavities, resulting in atypical presentations. The authors presented an aggressive case of a frontoethmoidal sinus osteoma with intracranial extension of an inflammatory sinonasal polyp. OBSERVATIONS A 30-year-old man with a history of chronic sinusitis presented to the hospital after three episodes of loss of consciousness, chronic worsening of headache, and decreased sense of smell. Rhinoscopic examination showed mucosal polyps arising from the infundibulum and the superior meatus. Computed tomography showed a fibro-osseous mass in the left frontal sinus. Subsequent brain magnetic resonance imaging with and without contrast revealed a large, septated intracranial left frontal lesion approximately 6.5 cm in diameter that was compressing the underlying brain parenchyma. LESSONS Intracranial extension of frontal sinus osteomas can have dire neurological implications. Early detection of lesions obstructing the paranasal sinuses outlet could prevent intracranial extension of the disease. The surgical approach to such tumors may be endonasal, open cranial, or a combination of both.

This case is related to a 52-year-old lady with proptosis, diplopia and diminution of vision due to a mass lesion in upper medial quadrant of the orbit. CT scan revealed a well defined mass in basi-frontal area with intra-orbital and intracranial extension. On exploring it was found to be mucopyocele of the frontal sinus. Surgical excision was done by external approach. The symptoms and signs resolved completely within a week. Frontal sinus mucopyoceles are benign and curable. Early recognition and management of them is of paramount importance because they can expand and cause local, orbital or intracranial complications.

Although osteogenic sarcoma occurs in the head and neck, it is almost exclusively limited to the maxilla and the mandible. Single, rare cases of this tumor in other facial bones are mentioned in foreign reports, but a discussion in the English literature has not come to our attention. The case history of a 58-year-old woman with a nonspecific frontal sinus pain and right-sided proptosis is presented. Plain radiographs of the paranasal sinuses revealed a radiopaque, calcific mass in the right frontal sinus approximately 3 × 5 cm in diameter. It was noted that the mass had an “onionskin” lamination. Laminography aided in the exact localization of the mass; further, it was noted on arteriography that the frontal sinus mass did not invade the dura. A frozen section biopsy at the time of craniotomy suggested a benign histologic lesion. However, subsequent review of permanent sections showed findings typical of an osteogenic sarcoma. The patient was treated with irradiation and in the first postoperative year has done well.

Sinonasal Malignant Melanoma

AbstractSinonasal malignant melanoma is rare and usually occurs in the nasal cavity. Presentation is often varied and occurs late in the natural history of the disease, resulting in a poor prognosis. A case is reported of a patient with malignant melanoma arising from the frontal sinus who presented with a forehead swelling and progressive confusion. A review of the literature on malignant melanoma in the nasal cavity and paranasal sinuses regarding its presentation, site of origin and principles of management is discussed.

Invasive mycotic infections can be effectively treated if rapid identification of fungus is obtained. We reported a case of coinfection byAspergillusandRhizopussp. involving nose, paranasal sinuses, orbit, and brain in a 68-year-old known hypertensive male. He was presented to ENT OPD with history of fever and intermittent headache since fifteen days along with history of right-sided nasal obstruction and proptosis since seven days. CT scan of brain and paranasal sinuses showed findings of pansinusitis with cellulitic changes in right orbit. MRI confirmed the same along with features of intracranial extension with focal meningitis in right frontotemporal region. Laboratory parameters did not conclude much except for leucocytosis and hyponatremia. Patient was taken for endoscopic debridement from nose and paranasal sinuses, and tissue was sent for microbiological and histopathological examination. Minced tissue was processed, and after 48 hrs of incubation two types of growth were identified, one was yellowish, granular, and powdery consistent withAspergillussp., and another was cottony and woolly consistent withRhizopussp. LCB mount confirmed presence ofAspergillus flavusandRhizopus arrhizus. Patient responded to therapy with IV amphotericin B and surgical debridement. On discharge patient's condition was good.

AbstractA 57-year-old man presented with a history of nasal obstruction of five to six years duration. 'Nasal polyps' were removed on several occasions. He had previously had an episode of paraplegia which resolved after the removal of a spinal tumour. Histology from both sites was thought to represent a malignant fibrous histiocytoma. On presentation the patient had computed tomographical (CT) evidence of extensive ethmoidal disease, with threatened intracranial extension. He also had evidence of lung and retroperitoneal disease with pancreas and kidney involvement. The ethmoidal disease was considered potentially lethal and therefore a craniofacial resection was performed. Review of all the histology revealed that the diagnosis was extranodal Rosai–Dorfman disease (sinus histiocytosis). The patient's course is described, and the literature on this disease of unknown aetiology is reviewed.

Abstract Background Coronavirus disease 2019 (COVID-19) is known to be associated with a myriad of viral, fungal, and bacterial co-infections. Rhino-orbital mucormycosis is a rare angio-invasive fungal infection which has shown a rising trend in the setting of COVID-19. Case presentation We describe the imaging findings in 3 cases of rhino-orbital mucormycosis in patients with history of COVID-19. All cases had varying involvement of paranasal sinuses extending into the orbital compartment while case 3 had intracranial extension of infection. Conclusions Rhino-orbital mucormycosis can have aggressive necrosis of the involved paranasal sinuses and orbits with or without cerebral extension. Hence, the correct diagnosis is imperative as prompt antifungal drugs and surgical debridement can significantly reduce mortality and morbidity.

BACKGROUND Chronic subdural hematoma (CSDH) is a commonly encountered condition in neurological and neurosurgical practice, but the presence of concomitant parkinsonism is extremely rare. Basal ganglia disturbance is a well-known underlying mechanism; however, few cases present with cerebral cortex compression as the cause of symptoms. OBSERVATIONS A 52-year-old man was referred to the authors’ hospital with a 5-week history of gait disturbance and suspected Parkinson’s disease. Neurological examination revealed a mask-like face, stooped posture, left-predominant rigidity, and postural instability. The authors initiated dopamine agonist administration, and brain magnetic resonance imaging (MRI) was scheduled. One week later, MRI showed bilateral CSDHs. The hematomas markedly compressed the bilateral cerebral cortex, whereas the midbrain and basal ganglia structures were intact. The patient underwent burr hole drainage and was discharged after 9 days without sequelae. LESSONS CSDH can cause parkinsonism by compressing the cerebral cortex, which is a part of the cortico–basal ganglia–thalamocortical circuit. Surgery leads to positive outcomes, as illustrated by this case, in which cerebral cortex compression caused parkinsonism.

We report a case of renal cell carcinoma (RCC) metastasis to the calvarium and describe a strategy for percutaneous embolization of hypervascular calvarial tumors with intracranial extension. An elderly patient with history of RCC presented with left-sided weakness. Imaging studies showed a large right frontoparietal calvarial mass with intra- and extracranial extension. The tumor was devascularized by direct puncture tumor embolization using Onyx 18, allowing subsequent operative resection without significant blood loss or the need for flap reconstruction of the scalp. Compared to more common endovascular approaches, direct-needle puncture embolization of transcalvarial masses may offer lower risk of injury to scalp vessels and underlying brain parenchyma.
