Abstract:
The first case of cerebral paragonimiasis was reported by Otani in Japan in 1887. This was nine years after Kerbert's discovery of the fluke in the lungs of Bengal tigers and seven years after a human pulmonary infection by the fluke was demonstrated by Baelz and Manson. The first case was a 26-year-old man who had been suffering from cough and hemosputum for one year. The patient developed convulsive seizures with subsequent coma and died. The postmortem examination showed cystic lesions in the right frontal and occipital lobes. An adult fluke was found in the occipital lesion and another was seen in a gross specimen of normal brain tissue around the affected occipital lobe. Two years after Otani's discovery, at autopsy a 29-year-old man with a history of Jacksonian seizure was reported as having cerebral paragonimiasis. Some time later, however, it was confirmed that the case was actually cerebral schistosomiasis japonica. Subsequently, cases of cerebral paragonimiasis were reported. However, the majority of these cases were not confirmed histologically. It was pointed out that some of these early cases were probably not Paragonimus infection. After World War II, reviews as well as case reports were published. Recently, investigations have been reported from Korea, with a clinicla study on 62 cases of cerebral paragonimiasis seen at the Neurology Department of the National Medical Center, Seoul, between 1958 and 1964. In 1971 Higashi described a statistical study on 105 cases of cerebral paragonimiasis that had been treated surgically in Japan.
Insights
Cerebral paragonimiasis, a parasitic brain infection, was first documented in 1887. Early cases were often misdiagnosed, highlighting the need for accurate diagnosis of this rare neurological condition.
Area of Science:
- Neurology
- Infectious Diseases
- Parasitology
Background:
- Cerebral paragonimiasis is a rare parasitic infection of the brain caused by Paragonimus flukes.
- The first documented case of cerebral paragonimiasis was reported in Japan in 1887.
- Early reports faced diagnostic challenges, with some cases misattributed to other parasitic infections like schistosomiasis.
Purpose of the Study:
- To review the historical context and diagnostic evolution of cerebral paragonimiasis.
- To highlight the challenges in early diagnosis and confirmation of Paragonimus brain infections.
- To underscore the importance of histological confirmation in diagnosing parasitic brain diseases.
Main Methods:
- Historical case review and analysis of early reports on cerebral paragonimiasis.
- Examination of diagnostic criteria and misdiagnoses in historical medical literature.
- Inclusion of data from later clinical and statistical studies from Korea and Japan.
Main Results:
- The initial report by Otani in 1887 described a fatal case with cystic brain lesions containing Paragonimus flukes.
- Subsequent reports included misdiagnosed cases, such as one initially identified as cerebral paragonimiasis but later confirmed as cerebral schistosomiasis japonica.
- Significant clinical studies emerged post-World War II, including a Korean study of 62 cases and a Japanese surgical study of 105 cases.
Conclusions:
- Accurate diagnosis of cerebral paragonimiasis has historically been challenging.
- Histological confirmation is crucial for differentiating Paragonimus infections from other neurological conditions.
- Continued research and reporting are essential for understanding the epidemiology and clinical spectrum of this parasitic brain infection.
