Intramuscular hemangioma of the scalene musculature masquerading as a paraganglioma: a case series

Pediatric intramuscular hemangioma in the submandibular triangle and other musculoskeletal presentations: A pediatric case series

BACKGROUND

Intramuscular hemangiomas (IMH) account for 0.8 % or less of all benign soft tissue tumors in the general population. Due to their uncommon nature, especially in the head and neck, they are often misdiagnosed and not included in the differential diagnosis.

METHODS

This study describes a case series of eleven pediatric patients with a diagnosis of IMH through a retrospective review of the electronic health records and archival records in the Department of Pathology at Children's Hospital of Colorado (CHCO).

RESULTS

The index case had a unique presentation in the submandibular triangle, while the remaining ten cases are appendicular and thoracolumbar in nature.

CONCLUSIONS

This case series contributes to the sparse scientific literature available regarding IMH, particularly in its head and neck presentation as relevant to otolaryngologists.

A Rare Clinical Report of Intramuscular Hemangioma of the Middle Scalene Muscle

Intramuscular hemangioma (IMH) is an uncommon benign vascular lesion, which develops in skeletal muscles and it accounts for <1% of all hemangiomas. The accurate diagnosis is often difficult because the clinical and radiological findings are not specific. The gold standard treatment of IMH is surgical resection. We present a rare clinical report of IMH of the middle scalene muscle that was treated successfully with preoparative embolization and surgical excision.

Posttraumatic Intramuscular Hemangioma Arising from Scalene Muscles in Supraclavicular Region

Intramuscular hemangiomas (IMH) account for <%1 of all hemangiomas and are rarely located in the head and neck region. The most common site of origin in the head and neck is the masseter muscle, whereas IMH originating from the scalene muscles are rarely seen. Surgical excision of intramuscular hemangioma is considered the main treatment modality. Here we present the case of a male patient aged 17 with IMH that occured after blunt trauma in the supraclavicular region, fed by the thyrocervical and costocervical trunks, and with an arteriovenous shunt.

Long-term effects of intracochlear electrical stimulation with looped patterns on tinnitus: A case study

Electrical stimulation by cochlear implant (CI) has been proven to be a viable treatment option for tinnitus in many recent studies. In addition, intracochlear electrical stimulation independent of an acoustic input appears to suppress tinnitus, at least in the short term. We conducted a case study to investigate the long-term effects of both standard CI and intracochlear electrical stimulation independent of an acoustic input on tinnitus in a patient with single-sided deafness and tinnitus. We found no negative effects of intracochlear electrical stimulation independent of an acoustic input on speech perception in noise. Furthermore, the additional use of a standard CI was advantageous for speech discrimination in our patient. We conclude that long-term tinnitus suppression can be achieved via intracochlear electrical stimulation with looped patterns. Our findings in terms of speech discrimination in our patient were consistent with those reported in previous studies.

Intramuscular Hemangioma in the Anterior Scalene Muscle Diagnosed by Core Needle Biopsy

Intramuscular hemangioma (IMH) is a rare, benign vascular lesion that frequently develops within skeletal muscles. Preoperatively, accurate diagnosis of IMH is often extremely difficult because of nonspecific clinical findings and the inaccuracy of fine-needle aspiration cytology. IMH is suspected in only 8% of preoperative diagnoses before surgical exploration. Here, we report a case of a 44-year-old man with a huge IMH in the anterior scalene muscle that was preoperatively diagnosed using ultrasonography-guided core needle biopsy, and was successfully treated based on preoperative clinical information.
