Breast and scrotal sparganosis: sonographic findings and pathologic correlation

Cerebral sparganosis masquerading brain neoplasm: A rare incidental case

Sparganosis is a parasitic infection caused by plerocercoid larvae of the genera Spirometra. Cerebral sparganosis is one of its most serious complications wherein clinical and imaging findings may pose diagnostic challenge. Here we present a case of cerebral sparganosis which mimicked as brain tumour on clinicoradiological examination. The case is reported in view of its rarity in India and the need for awareness of the entity.

Axillary sparganosis, changes in ultrasound images over six months: A case report

Sparganosis is an infestation caused by a tapeworm belonging to the genus Spirometra. The typical radiologic findings of sparganosis describe elongated, folded, band or tubular, hypoechoic structures with surrounding increased echogenicity in ultrasonography. These imaging features have been highly consistent with pathology results. Here, we report an interesting case of axillary sparganosis that manifested changes on ultrasound images over a period of 6 months.

Very High- and High-Frequency Ultrasound Features of Cutaneous Larva Migrans

Cutaneous larva migrans is a common infestation among travelers. Although the diagnosis may be suspected clinically, cases can show atypical presentations. We present the ultrasound features of 4 cases at 18 and 70 MHz. Small linear hyperechoic and hyper-refringent subepidermal and intrafollicular structures suggestive of fragments of larvae, hypoechoic dermal and hypodermal tunnels that match with dilatation of lymphatic ducts, and inflammatory dermal and hypodermal ultrasound signs can support the diagnosis. This work suggests that larvae can penetrate the cutaneous basement membrane through the ostia of the hair follicles and potentially disseminate through the dermal and hypodermal lymphatic network.

Sparganosis of the Unilateral Breast: A Case Report

Sparganosis is a parasitic infection caused by the sparganum, the plercercoid of the genus Spirometra. The preoperative diagnosis of breast sparganosis is difficult in most cases because it is a rare parasitic infection less than 2% of all cases. We report a 62-year-old woman case of breast sparganosis that were confirmed by surgical removal of worms from the right breast. The radiologic images of the patient also revealed characteristic features of breast sparganosis. The patient described the migrating palpable breast mass, which strongly suggested the possibility of breast sparganosis. The treatment of choice and confirmative diagnosis for sparganosis are complete surgical extraction of the sparganum irrespective of infected site. Inspection of the mass site with detailed medical history and radiological examinations are important for preoperative diagnosis of sparganosis patients.

Breast sparganosis and incidentally detected subcutaneous and intramuscular sparganosis at several sites: case report and literature review

Sparganosis is an infestation caused by a tapeworm belonging to the genus Spirometra. We describe a surgically confirmed case of sparganosis in several organs including the breast, both lower extremities, anterior chest wall, inguinal area, and the psoas and gluteus muscles. Mammography, ultrasonography, and MRI imaging findings for our patient were characteristic of sparganosis. Ultrasonography revealed multiple elongated tubular hypoechoic structures with surrounding increased echogenicity. Mammographic findings included tortuous, lobular, and tubular densities. Short tau inversion recovery (STIR) MR images contained several elongated tubular tracts of high signal intensity. These imaging features were highly consistent with pathology results.

Case report: Molecular diagnosis of subcutaneous Spirometra erinaceieuropaei sparganosis in a Japanese immigrant

We report a case of subcutaneous sparganosis in a 68-year-old female Japanese immigrant in Germany. The patient complained of a painless erythema caudal of the umbilicus with a palpable subcutaneous cherry-sized lump. Polymerase chain reaction on formalin-fixed parasite tissue identified Spirometra erinaceieuropaei as the causative agent; the proliferative form of sparganosis, which is caused by the branching and disseminating Sparganum proliferum, could, thus, be excluded. From the excised sparganum, an immunofluorescence test was established and revealed an antibody response directed against the parasite's tegument. Histological key features of the plerocercoid that facilitate diagnosis with different stains are presented.
