Abstract
Cerebral cavernous malformation is an angiographically occult, well-circumscribed, benign hamartoma consisting of thin-walled sinusoidal vascular channels. Intracranial mucormycosis represents one of the most severe manifestations of mucor infection. We, hereby, report a case of cavernous malformation made rarer with concomitant mucormycosis. A 22-year-old female presented with left-sided facial seizures since age of 7 years and headache for the past 3 years. Magnetic resonance imaging brain revealed a right posterior frontal lobe cavernous malformation. Right frontal craniotomy with excision of cavernoma was done. Gross examination showed a solid cystic mass with multiple mulberry protrusions. Histopathological examination revealed features of cavernous malformation with evidence of mucormycosis. A final diagnosis of cavernous malformation with mucormycosis was rendered and microbiological studies were advised. To the best of our knowledge, this is the first case report of a cerebral cavernous malformation with mucormycosis in an immunocompetent patient without any risk factor.

Abstract
Background Mucormycosis involves life-threatening rapidly progressive angioinvasion with infiltration across tissue planes, resulting in necrosis and thrombosis, most commonly seen in the setting of immunocompromised states. We describe 2 cases of isolated cerebral mucormycosis in immunocompetent adults and describe this syndrome in detail in the context of a systemic literature review. Methods Using the criteria (1) isolated cerebral disease, (2) mucormycosis (by polymerase chain reaction, culture, or pathology), and (3) affected an immunocompetent individual, we identified 53 additional cases from 1969 to 2020. Results Of these 55 cases, ~60% occurred in men, >70% were in patients under age 35, 92% were associated with intravenous drug use, and >85% had infection centered in the basal ganglia. Many presented with cranial nerve deficits, headache, focal weakness, or altered mental status. Conclusions No patient survived without amphotericin, and steroid administration was associated with worse outcomes. Given the current opioid crisis, this syndrome may be seen more frequently.

Abstract
Isolated cerebral mucormycosis is a clinical type of mucormycosis that is estimated to account for 8% of all mucormycosis cases. The clinical symptoms of isolated cerebral mucormycosis are elusive, and thus conventional techniques often lake sensitivity and specificity. Moreover, cultures are often negative, even when direct microscopy examination is positive. Although histopathology will probably remain the gold standard for the diagnosis of mucormycosis, obtaining a biopsy specimen is not always feasible in most vulnerable populations. Thus, molecular approaches are currently used as an advantageous assistant examination method to improve the early identification of the causative agent and subsequently guide therapy to improve the prognosis of patients. Here, we report a case of isolated cerebral mucormycosis caused by Rhizopus microspores in a healthy young adult that was identified using next-generation sequencing technology.

Abstract
Background: Mucormycosis is a rare, aggressive fungal disease with high mortality, typically presenting as rhinosinusitis in immunocompromised patients. Case Description: A 43-year-old man with a history of intravenous drug use, Hepatitis C, and no evidence of immunocompromise presented with worsening balance problems. He had received intravenous antibiotics 2.5 years earlier for local infection after injecting heroin into a neck vein. Imaging studies revealed a lesion, likely of neoplastic origin. At resection, purulent fluid sampled by neuropathology revealed right-angled, branching hyphae, suggesting mucormycosis. No further resection was performed, no other disease sites were found, and HIV findings were negative. Two weeks postoperatively, he developed renal failure; intravenous antifungal treatment and hemodialysis were discontinued. When kidney function recovered 2 weeks later, he declined additional treatment. Conclusion: In our immunocompetent patient, both the location of the infection in the posterior fossa and its slowly progressive characteristic were unique variations of this typically aggressive disease.

Abstract
Rhinocerebral mucormycosis is a rare disease, affecting almost exclusively patients with known predisposing conditions such as diabetes mellitus, immunocompromised status, haemochromatosis or major trauma. Subsequent to a case of rhinocerebral mucormycosis in a 78-year-old woman without any known risk factor, we reviewed the published English-language literature and found an additional 72 cases. Reviewing all the published case series of mucormycosis involving any site, the proportion of apparently normal hosts among cases of rhinocerebral mucormycosis was found to be 9.06% (95% confidence interval 6.7-11.8). These findings suggest that rhinocerebral mucormycosis in patients without known predisposing factors is more prevalent than was previously believed.

Abstract
Invasive zygomycosis is a devastating fungal infection seen mostly in immune-compromised patients. We present a case of a 48-year old diabetic man, with aplastic anemia, who developed severe pulmonary mucormycosis that led to his rapid demise despite early diagnosis and treatment with liposomal amphotericin B. We also conducted an extensive review of the pathogenesis of invasive zygomycosis, its history, predisposing factors, clinical aspects, diagnostic modalities, treatment options, morbidity and mortality.

Abstract
BACKGROUND Cerebral mucormycosis without rhino-orbital or systemic involvement is an extremely rare condition mostly associated with parenteral drug abuse. CASE DESCRIPTION We report the case of a 42-year-old woman who presented with hemiparesis of the left side and altered mental status. Neuroradiologic workup demonstrated an inflammatory lesion involving the right basal ganglia. Proton magnetic resonance spectroscopy demonstrated features consistent with a pyogenic abscess. Computed tomography-guided stereotactic biopsy led to the diagnosis of cerebral mucormycosis. Parenteral AMB-L treatment was conducted, but the patient worsened clinically, presenting with a complete hemiplegia, and cerebral magnetic resonance imaging (MRI) scans demonstrated a voluminous abscess formation. Then, under stereotactic guidance, a surgical endoscopic debridement of the abscess cavity associated with the placement of an Ommaya reservoir was performed. Systemic and intralesional treatment with AmB associated with an adjunctive immune therapy was conducted. At 3-year follow-up, the patient had recovered partially from her left hemiplegia, allowing her to walk without help, and cerebral MRI scans showed complete resorption of the abscess. CONCLUSION Our good results suggest that surgical endoscopic debridement associated with intravenous and intracavitary antifungal therapy might be valuable in treating voluminous deep-seated mucormycotic lesions.

Abstract
Isolated cerebral mucormycosis is a rare but life-threatening infection that generally occurs in patients with intravenous drug abuse or immune deficiency. We report a case of primary cerebral mucormycosis in a healthy adult. Whole body autopsy in this case revealed cerebral mucormycosis with prominent vascular pathology and hemorrhagic necrosis. No nasal sinus, orbital or other primary locus of fungus infection was discovered. Review of the previously reported 30 cases of isolated cerebral mucormycosis revealed associated systemic predisposition in 11 patients and history of intravenous drug abuse in 17 cases. In the remaining two cases, the diagnosis of fungal infection was made only after surgical exploration. Early tissue diagnosis and the consequent surgical excision of the necrotic tissue and aggressive antifungal therapy might salvage life in this fatal condition.

Abstract
Rhinocerebral mucormycosis is a rapidly progressing, often fatal fungal infection that occurs commonly in diabetics and immunocompromised individuals. We present 2 cases of rhinocerebral mucormycosis with a paranasal mass. One patient had an intracranial extension. Nasal scrapings and fine-needle aspiration cytology (FNAC) of the paranasal masses showed fungal hyphae morphologically resembling Mucor. Surgical material showed features of mucormycosis. FNAC and scrape smears can give a conclusive diagnosis of mucormycosis, and the patient can be treated with appropriate antifungal therapy and surgical debridement. Preoperative cytology is an effective technique to establish a diagnosis of mucormycosis and obviates the need for a preoperative biopsy.

Abstract
Cerebral mucormycosis (without associated involvement of and invasion from the nasal sinuses and turbinates) is an extremely rare opportunistic infection of the central nervous system. We report the case of an intravenous drug abuser (who was negative for the human immunodeficiency virus) who presented with hemiparesis on the right side, slurred speech, altered mental status, and an unsteady gait. Imaging studies revealed a large left-side basal ganglia lesion. A stereotactic biopsy obtained a tissue sample that revealed wide, nonseptated hyphal fragments with granulomatous inflammation. The patient was treated with 3 gm of amphotericin B during a 5-month period. The patient had no residual neurological dysfunction after treatment. Open surgical resection was not employed. This case suggests that stereotactic biopsy followed by long-term amphotericin B therapy, in lieu of open surgical resection, represents a viable treatment option for this rare disorder.

Abstract
Zygomycosis of the basal ganglia should be recognized as a syndrome in intravenous drug users associated with a culture-negative cellular CSF, fever, lethargy, and lesions apparent on contrast-enhanced CT scans of the head. The infection is most likely the result of intravenous inoculation of fungal spores. This entity is different from the rhinocerebral zygomycosis seen with diabetes mellitus and other diseases. In the rhinocerebral form, there are external signs of the disease with involvement of the orbit, paranasal sinuses, and palate. In these drug users, infection was directed to areas deep within the brain.

Abstract
In addition to the well-known infectious complications of intravenous narcotic abuse, a much rarer and more recently recognized association between intravenous narcotic addiction and mucormycotic abscesses of the central nervous system has been described. Only four cases have been cited in the literature, with a mortality rate of 100 percent in this group. This report describes a narcotic abuser who presented with obstructive hydrocephalus and a mucormycotic abscess of the brain stem, and recovered. Central nervous system mucormycosis should be included in the differential diagnosis of drug abusers who present with a rapid deterioration in neurologic status.
