We describe a case of benign inverted papilloma with intracranial extension treated with endoscopic resection combined with craniotomy. Intracranial involvement of inverted papilloma, in the absence of malignancy, is uncommon. We present an analysis of the literature identifying the characteristics and outcomes of benign intracranial inverted papilloma. PubMed database was searched using keywords intracranial, inverted or inverting, and papilloma. There are 17 reports of benign inverted papilloma with intracranial extension reported with a mean age of 49...

This study was conducted to describe a retropharyngeal myxoma and discuss clinical concerns regarding this pathology and a retropharyngeal site of occurrence. We present a case report and review of literature. A 71-year-old woman presented with mild right neck pressure for 3 weeks. Imaging studies and head neck examination confirmed a 5.3 × 3.1 × 1.0 cm retropharyngeal mass with no communication to the vertebral column but was intimately involved with the pharyngeal mucosa. A transoral fine needle aspiration biopsy suggested a possible spindle cell neoplasm...

Carotid pseudoaneurysms of petrous localization are rare. They are mostly due to trauma, tumoral or infectious diseases, or a result of iatrogenic complications after skull base surgery. Symptoms such as facial paralysis are exceptional and have rarely been described in the literature until now. We report the case of a 64-year-old woman, who developed left peripheral facial paralysis induced by two carotid pseudoaneurysms in their intrapetrous section. The treatment is endovascular, despite the high morbidity rate...

Esthesioneuroblastoma (ENB) is an uncommon malignant tumor derived from the specialized neuroepithelium of the upper nasal cavity. The largest case series and meta-analyses suggest the combination of surgery and radiotherapy as the gold standard treatment for ENB. However, an increasing number of case series have reported excellent survival and few complications with minimally invasive endoscopic resection (MIER) in conjunction with radiotherapy of EBN in early stages of the disease. In this case report, the authors describe the first case of ENB in a young adult man who was human immunodeficiency virus (HIV)-1 and Hepatitis C virus (HCV) coinfected...

Endolymphatic sac tumors (ELSTs) are rare neuroectodermal neoplasms arising within the posterior petrous bone. We present a case of a 21-year-old man who presented with a 6-month history of intermittent morning headaches, fatigue, diplopia, and gait ataxia. Imaging and surgical pathology identified an adenocarcinoma of the endolymphatic sac compressing the cerebellum and brain stem. The tumor and multiple metastases were treated with surgery, radiation, and radiosurgery. Following insertion of a ventriculoperitoneal shunt for hydrocephalus, he developed symptomatic tension pneumocephalus secondary to radionecrosis of his petrous bone, requiring flap reconstruction and use of a programmable shunt valve complemented by hyperbaric oxygen (HBO) therapy...

Neurenteric cysts are considered congenital lesions that may slowly expand over time. Although more commonly found in the spinal canal, they may be found intracranially, particularly in the posterior fossa. Here, we present an unusual case of a large, rapidly expanding histologically confirmed posterior fossa neurenteric cyst in a 53-year-old woman, who presented with quadriparesis. Computed tomography imaging done ~1.5 years before admission failed to demonstrate any obvious abnormality; however, the lesion had grown to 4 cm in maximal dimension at presentation with significant mass effect...

Inverted papillomas (IP) are considered benign lesions with a prevalence up to 4% among all sinunasal tumors; however, invasive growth and varying tendency for malignization are reported in literature. We report the case of a 69-year-old woman suffering from a large, aggressively growing IP invading the orbit, skull base, and frontal lobe of the brain. Within only 3 months' time the papilloma showed transformation into an invasive carcinoma, leaving surgical therapy in vain due to explosive recurrence. Intracranial and intraorbital expansion by IP is possible despite histology not showing signs of malignancy initially...

Inflammatory pseudotumor (IPT) is a benign entity that may present as a solid mass mimicking a malignant neoplasm. Histologically, they are composed of varying proportions of myofibroblastic spindle cells, lymphocytes, and plasma cells. Skull base IPT is rare and usually occurs in adults with no sex predilection. The skull base IPT typically presents with headache, and/or cranial nerve palsy. There is no consensus regarding treatment of skull base IPT due to its rarity. Surgical resection and corticosteroid therapy have generally been used...

The authors report two cases of coexisting Rathke cleft cyst (RCC) and pituitary macroadenoma. Both patients presented at the university hospital with pituitary apoplexy symptoms of sudden-onset headache while undergoing treatment with Coumadin (warfarin). Magnetic resonance imaging was consistent with a pituitary adenoma in one case and RCC in the other. Intraoperative findings and pathological work-up identified RCC along with adenomatous tissue displaying hemorrhagic pituitary adenoma in one and hemorrhagic RCC in the other...

We report the first case of hepatoid adenocarcinoma of the skull base, as well as the first reported case in the head and neck region. Hepatoid adenocarcinoma is a rare, aggressive, extrahepatic malignancy with a distinct morphological similarity to hepatocellular carcinoma, in the absence of primary hepatic disease. A 45-year-old man presented with sinus headaches and retro-orbital pain and was found to have a nasopharyngeal mass on endoscopy and a large, destructive sinonasal mass extending intracranially on imaging...

In most series, 90% of cerebellopontine angle tumors are vestibular schwannomas. Meningiomas and epidermoid tumors follow with decreased frequency. Ganglioneuroma is a benign tumor usually found in the retroperitoneum and posterior mediastinum. We report a case of a 21-year-old man with gradual sensorineural hearing loss and a minimally enhancing lesion of the internal auditory canal, which was excised through a middle fossa approach and found histologically to be a ganglioneuroma. Like vestibular schwannomas, these lesions are benign in nature and may be managed in a similar fashion, although the possibility of malignant transformation may support surgical resection over conservative management or radiosurgery...

Nasal gliomas are congenital, nonmalignant rests of neuroglial tissue that typically present as a craniofacial mass. The differential diagnosis of such masses includes lesions that often require the involvement of various surgical subspecialties, including otolaryngology, neurosurgery, plastic surgery, and ophthalmology. Early surgical excision of these masses is advised to minimize nasal and craniofacial distortion. Accordingly, early diagnosis and management planning are paramount, and advances in prenatal imaging are creating a new role for obstetricians and radiologists in the initiation of diagnostic and therapeutic interventions...

Chondroblastoma of the temporal bone is a rare condition. Chondroblastomas account for less than 1% of primary bone tumors, and those involving the temporal bone represent a tiny fraction of these tumors with most arising from the knee, rib, and pelvis. We present a case series of two patients who presented with chondroblastomas of the temporal bone over a period of 8 years to the St. Vincent's Hospital in Melbourne, Victoria, Australia. In particular, we outline the presenting complaint, diagnostic imaging undertaken, and the importance of preoperative histopathology in coming to the diagnosis and subsequent resection undertaken...

The case of a 51-year-old man with a large temporal mass is presented. The mass eroded the floor of the middle fossa medially to the sphenoid sinus. A combined approach with neurosurgery and otolaryngology was performed to achieve maximal resection of the mass. Pathology was typical for chondroblastoma: a rare, benign but locally invasive chondroid tumor. Genetic testing revealed a translocation of (2;5) (q33;q13). This is a unique genetic mutation in all chondroid tumors to our knowledge. The diagnostic utility or role of this mutation in the pathobiology of this tumor remains to be determined...

Computed tomography (CT), performed in a healthy 28-year-old man after minor head injury, detected a frontal base tumor. Neurological examination revealed left hyposmia. On magnetic resonance imaging scans, there was a heterogeneously enhanced tumor located in the left paramedian frontal base with extension into the left ethmoid sinus. Angiography showed a hypervascular mass in the left anterior cranial fossa; it was mainly fed by the left ethmoidal artery. Positron emission tomography scanning showed moderate accumulation of 11-methylmethionine and low accumulation of 18-fluorodeoxyglucose (FDG) at the tumor site...

We describe two cases of dural arteriovenous fistula (DAVF) developing in a delayed fashion after translabyrinthine resection of cerebellopontine angle tumors. Two patients in an academic tertiary referral center, a 46-year-old woman and a 67-year-old man, underwent translabyrinthine resection of a 2-cm left vestibular schwannoma and a 4-cm left petrous meningioma, respectively. Both patients subsequently developed DAVF, and in each case the diagnosis was delayed despite serial imaging follow-up. In one patient, cerebrospinal fluid diversion before DAVF was identified as the cause of her intracranial hypertension; the other patient was essentially asymptomatic but with a high risk of hemorrhage due to progression of cortical venous drainage...

Reports of intracranial retained foreign bodies are relatively rare in the literature. Such objects can cause numerous complications requiring removal, such as infection, persistent cerebrospinal fluid (CSF) leak, or new-onset seizures. The transnasal endoscopic approach provides an excellent alternative to craniotomy for repairing middle cranial fossa (MCF) defects. We describe a case of a 57-year-old woman with a self-inflicted bullet piercing the MCF, creating a persistent CSF leak. The details regarding the removal of this penetrating foreign body from the MCF, including the unique management in the setting of a contralateral spontaneous CSF leak, are discussed...

Nonmissile penetrating intracranial injuries are uncommon events in modern times. Most reported cases describe trajectories through the orbit, skull base foramina, or areas of thin bone such as the temporal squama. Patients who survive such injuries and come to medical attention often require foreign body removal. Critical neurovascular structures are often damaged or at risk of additional injury resulting in further neurological deterioration, life-threatening hemorrhage, or death. Delayed complications can also be significant and include traumatic pseudoaneurysms, arteriovenous fistulas, vasospasm, cerebrospinal fluid leak, and infection...

There is a surge in fungal infections of the central nervous system due to an increase in the incidence of immunocompromised state and widespread use of antimicrobials. Despite myriad clinical presentations and skull base syndromes associated with Aspergillus infections, aspergilloma in the sella is relatively rare. We report a rare case of aspergilloma of the sella and parasellar region in a patient operated for acromegaly. A 30-year-old diabetic patient underwent two surgeries for a growth hormone-secreting pituitary adenoma, which included a transsphenoidal approach...

Petrous apex cholesterol granulomas (PACG) are uncommon lesions. Recurrence following transcranial or endonasal approaches to aerate the cyst occurs in up to 60% of cases. We describe the technical nuances pertinent to the endonasal endoscopic management of a recurrent symptomatic PACG and review the literature. A 19-year-old woman presented with a recurrent right abducens nerve paresis. Four months prior, she underwent an endonasal transsphenoidal surgery (TSS) for drainage of a symptomatic PACG. Current imaging documented recurrence of the right PACG...
