“…Unusual localizations of human hydatid disease can affect all tissues and organs: the gastrointestinal tract, pancreas, spleen, urogenital system, retroperitoneum, peripheral nervous system, bones, endocrine glands, eyeball, heart, soft tissues ... etc. [7][8][9][10][11][12][13][14] Central nervous systems involvement in hydatidosis is rare compared to somatic locations: 1-5%.

Central nervous system involvement in hydatidosis is rare compared to other somatic localizations: 1-5%. It is schematically divided into two major types: cerebral involvement and spinal involvement. The brain is a rare localization of hydatid cyst accounting for only 2% of all hydatid disease. The psychiatric manifestations revealing cerebral hydatidosis remain exceptional and often unrecognized and neglected by practitioners despite their potential severity. We report two original observations of fatal cerebral hydatidosis revealed by behavior change (psychomotor agitation, aggressiveness, persecutory delusion, and auditory and visual hallucinations) insufficiently explored in two women aged 45 and 17. The possibility of cerebral hydatidosis must always be evoked in front of any psychiatric symptomatology that remains unexplained in endemic areas for echinococcosis.

“…Echinococcosis is a zoonosis that continues to be a major public health problem in many parts of the world where it is still endemic [1][2][3][4][5]. All organs and/or tissues may be the site of single or multiple hydatid cyst (Kc) [6,7]. The most frequent locations of human hydatid disease are the liver (65-70% of cases) and the lungs (25% of cases) [2,4].…”

“…The extra-pulmonary and extrahepatic sites are exceptional and little known. They are therefore described as atypical or unusual by most authors [6][7][8], or even "ectopic" and "aberrant" by some [9].…”

Primary Hydatid Cyst of the Thyroid Gland Revealed by Primary Hypothyroidism

Introduction:The thyroid localization of the hydatid cyst (HC) remains exceptional and unusual even in countries where this Parasitosis is still endemic: its frequency varies from 0.1 to 0.6 ‰ depending on the series. It is most often asymptomatic or resulting in anterior cervical swelling or more rarely a hoarseness of the voice. We report an original observation of thyroid HC revealed by primary hypothyroidism.Observation: An eight-year-old patient with no notable pathological history was explored for normochromic normocytic anemia at 8 g/dl. The clinical examination found neither jaundice nor splenomegaly. There was anterior cervical swelling that was painless and lateralized to the right. No lymphadenopathy or other palpable mass was noted. Biology revealed peripheral hypothyroidism with TSH at 7.83 μIU/ml. The balance of hereditary hemolytic anemias was negative. Cervical ultrasonography and CT showed an anechoic anterior cervical mass 2.51 cm in diameter, occupying the right thyroid lobe, without micro calcifications, intracystic vegetation, or adenopathies. Hydatid serodiagnostic was positive. The diagnosis of thyroid HC was confirmed by histological examination post loboishmectomy. The total blood count and TSH were spontaneously corrected after one month of the surgery. Conclusion:The diagnosis of HC is worthy of mention in the presence of peripheral hypothyroidism with increased thyroid gland volume, especially in endemic areas. This location can sometimes hide associated thyroid neoplasia.

“…At the same hospital in Erzurum, patients with AE were also operated for liver transplantation due to hepatic alveolar echinococcosis (341,345). The recent epidemiological data on CE cases in humans were expressed as follows: the regional incidence of CE varied depending on epidemiological differences and ranged 0-79 per 100,000 population; the prevalence of CE was also reported as 50-400 cases per 100,000; the average incidence of CE in Turkey was given as 3.4 per 100,000 inhabitants (346).…”

Zoonotic infections are globally important diseases and lead to huge economic losses in both low-and middle-income and high-income countries. Global warming, environmental and ecological changes, illegal movement of animals and humans, regional civil wars, and poverty are predisposing factors for the emergence of zoonotic infections and their distribution worldwide; they are also a big threat for the future. In addition, environmental pollution and antimicrobial resistance are immense serious threats and dangers to prevent and control zoonotic infections. The natural location of Turkey allows many emerged or re-emerged infections with zoonotic characteristics by animal movements, such as bird immigrations, and by human movements due to civil wars as seen with regional refugees. Numerous zoonotic diseases, including 37 bacterial, 13 fungal, 29 viral, 28 parasitic (3 trematodes, 7 cestodes, 10 nematodes, and 8 protozoan), and totally 107 infections, have been reported from Turkey to date. Additionally, many ectoparasitic zoonoses within 15 different arthropod groups and one leech infestation have been reported from Turkey to date. The "One Health" initiative is particularly relevant for developing strategies to combat zoonotic diseases. In this article, we review the occurrence of zoonotic diseases in man and animals in Turkey in the light of the "One Health" perspective.

Abstract: Since hydatid cyst can be found in all the body sites, it should be taken into account in the differential diagnosis of all cystic lesions.
