Toxocariasis

Toxocariasis has a broad clinical spectrum, from asymptomatic to systemic illness. However, cerebral toxocariasis has rarely been reported. We experienced a patient who presented with seizure and memory disturbance after treatment for visceral larva migrans of toxocariasis. Laboratory findings included eosinophilia, cerebrospinal fluid (CSF) pleocytosis, and positive results for toxocariasis in the serum and CSF. The patient showed marked improvement after combined albendazole and steroid treatment. This case indicates that cerebral toxocariasis is an unusual cause of cognitive dysfunction and seizure.

Hepatic toxocariasis is a type of visceral larva migrans caused by the migration of second-stage larvae of certain nematodes such as Toxocara canis to the liver. Histologically, the condition is characterized by granulomatous lesions containing eosinophils and inflammatory cells. We report a case of hepatic toxocariasis with atypical clinical and radiologic findings presenting as distinct, solitary hepatic nodule detected in a middle-aged woman.

The laparoscopy-assisted hepatic resection has been introduced for solitary benign or malignant hepatic tumors. We successfully had undergone left lateral sectionectomy with assistance of laparoscopy. Forty-three year old male patient was admitted for diagnosis of liver mass. Abdominal computed tomography showed a 2 cm sized single nodular tumor in segment 3 which was consistent with hepatoma. He underwent laparoscopy-assisted left lateral sectionectomy using Cavitron Ultrasonic Surgical Aspirator and Ultrasonic Shears. The patient discharged without any complications in the 8th postoperative day. The pathologic findings of nodule were consistent with the eosinophilic abscess of liver. Left lateral sectionectomy of liver can be conducted safely with assistance of laparoscopy.

Toxocariasis is known as visceral larva migrans in humans and it is caused by T. canis and T. catis, especially in children, but it is less commonly reported in adults. Although several cases of toxocariasis in adults have been reported, there have been no descriptions of toxocariasis involving the liver or, the lungs and the pleura. We report here on a case of T. canis infection in an immunocompetent adult with peripheral eosinophilia, elevated serum levels of Ig E and CT findings displaying multiple focal air space consolidations in the lungs, bilateral pleural effusion and low attenuated hepatic nodules.

Toxocariasis is an infection in a human host caused by Toxocara canis or Toxocara cati larvae. Clinical manifestations are classified according to the organs affected, such as visceral larva migrans (VLM) and ocular larva migrans (OLM). Epidemiological evidence suggests that OLM tends to occur in the absence of systemic involvement and vice versa, which has led to two manifestations of this infection being reclassified as VLM and OLM. No case of a patient with VLM combined with OLM has been reported in Korea. Here, we report a case of VLM combined with OLM in a 51-year-old female caused by massive ingestion of raw cow meat, manyplies, and liver.

Visceral larva migrans is a syndrome presented chronic peripheral eosinophilia, hepatomegaly with eosinophilic granuloma. Originally it results from migration of second stage larva of Toxocara species, animal ascarides, but there are many other causative parasites. It's difficult to detect causative parasite, although immunohistochemical methods like ELISA or Ouchterlony method have been introduced. If the larva were dectected, it's not easy to discriminate causative one from others because of similarities of morphology. Most cases have self-limited course. Only in severe infection, antiparasitic treatment, augmented by corticosteroid when allergic symptopms are also present, is required. Clinical presentations have varieties of spectrum, hepatomegaly with eosinophilic granuloma is most common. Some cases of pulmonary, ocular and CNS symptoms were reported. We now report a case of visceral larva migrans, presented submucosal tumor or diverticulitis in the ascending colon and went through laparoscopic right hemicolectomy. The diagnosis was made with microscopic examination of operation tissue.

The macula may be displaced by retinal scarring or fibrous strands, often as a result of retrolental fibroplasia. The displacement is usually temporal and may occur bilaterally but may also be superior or inferior and unilateral after severe retinitis(Toxocara canis). Ectopic macula causes a displacement of the visual line and thus occasionally produces a large positive angle kappa that simulates exotropia. Displacement of the macula also may be congenital. Ocular toxocariasis is recognized to be an important cause of childhood blindness. It usually results as a sequela of systemic infestation with the second or third stage larva of T. canis(visceral larval migrans). The roundworm Toxocara canis is an intestinal parasite of dogs. Humans are infected accidentally by ingesting infective ova from contaminated soil. Only on rare occasions has ocular involvement been reported in visceral larva migrans. Ocular toxocariasis can assume a variety of clinical forms. The authors experienced a case of ectopic macula in presumed ocular toxocariasis which was diagnosed on the basis of the clinical appearance and a history of exposure to puppy. A review of this subject is provided, with emphasis upon pathogenesis, clinical features, diagnostic approaches and therapeutic techniques.

Toxocariasis is a parasitic infection caused by the roundworms Toxocara canis or Toxocara cati, mostly due to accidental ingestion of embryonated eggs. Clinical manifestations vary and are classified as visceral larva migrans or ocular larva migrans according to the organs affected. Central nervous system involvement is an unusual complication. Here, we report a case of multiple cerebral infarction and concurrent multi-organ involvement due to T. canis infestation of a previous healthy 39-year-old male who was admitted for right leg weakness. After treatment with albendazole, the patient's clinical and laboratory results improved markedly.

Human toxocariasis is a common helminthozoonosis due to the infestation of toxocara canis or toxocara cati larvae, and is a common cause of blood eosinophilia in Korea. Toxocariasis has various clinical manifestations depending on the involved organ, and cardiac involvement can range from asymptomatic to fulminant myocarditis with cardiogenic shock. Treatment of toxocariasis is based on corticosteroid and anthelmintic therapies. Here, we report a case of a 57-year-old male with eosinophilic myocarditis caused by toxocariasis as diagnosed via serial echocardiography follow up.
