Insights

Cryptococcal ventriculitis, a rare central nervous system infection, can cause gait disturbance and cognitive impairment. Prompt diagnosis and extensive treatment are crucial for managing this serious fungal infection.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Medical Imaging

Background:

  • Cryptococcal infections primarily affect immunocompromised individuals but can occur in the general population.
  • Central nervous system (CNS) involvement, particularly ventriculitis, is a rare but severe complication of cryptococcosis.
  • Progressive gait disturbance and cognitive impairment are potential neurological manifestations.

Observation:

  • A 54-year-old man presented with gait disturbance and cognitive impairment.
  • Brain MRI revealed periventricular white matter hyperintensities and leptomeningeal enhancement.
  • Cerebrospinal fluid analysis demonstrated lymphocytic pleocytosis, elevated protein, low glucose, and positive cryptococcal antigen.

Findings:

  • The patient was diagnosed with cryptococcal ventriculitis, a rare manifestation of CNS cryptococcosis.
  • Treatment involved a prolonged course of combination antifungal therapy, including liposomal amphotericin B, fluconazole, voriconazole, and flucytosine.
  • Follow-up MRI showed septum formation, indicating residual ventriculitis despite treatment.

Implications:

  • This case highlights the importance of considering cryptococcal infection in patients with unexplained neurological symptoms and CSF abnormalities.
  • Ventriculitis, though uncommon, is a serious complication of cryptococcosis requiring aggressive and prolonged antifungal management.
  • Early recognition and comprehensive treatment are essential for improving outcomes in CNS cryptococcosis.

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Fungal Group Zygomycota01:29

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
