“…The term is synonymous with heterotopia and ectopia, which are defined as the proliferation of normal cells in an abnormal location [ 1 ] and an ectopic, histologically normal mature tissue. [ 18 ] Hamartoma is defined as a lesion containing mature and well-differentiated ectoderm and mesoderm derivatives that appear in abnormal locations [ 2 , 19 ] ; usually, 1 component dominates. [ 2 ] Hamartoma is similar to choristoma in that, both are benign proliferations of mature tissue, but a hamartoma is a malformation resembling the tissue at its site of origin, while the choristoma contains components that do not usually appear at the anatomic location where it is located.…”

Rationale: Intraspinal choristoma is a relatively uncommon intervertebral canal tumor. Prior to our reports, only 2 cases of intraspinal choristoma had been reported. Because this disease is not common and looks like a mass of fatty tissue on the magnetic resonance imaging (MRI), intraspinal choristoma can be easily misdiagnosed as teratomas or lipomas (like the case of this article presenting) without a pathology report. So if a lumber intraspinal lesion is discovered in a clinical examination, intraspinal choristoma should be considered as a differential diagnosis. We present a case of intraspinal choristoma that is unlike any other reported case. Patient concerns: A 35-year-old woman with left lower extremity hypoesthesia and burning-like pain in the lumbar region for 1 month visited the local hospital for plain lumbar spine MRI. The patient was diagnosed with a lumbar space-occupying lesion. A second plain lumbar spine MRI scan and a MRI scan with enhancement were performed in our hospital to confirm the presence of a congenital lipoma in the spinal canal. A postoperative biopsy of the lumbar spinal mass indicated that the mass was an intraspinal choristoma located in the spinal canal. Diagnosis: Intraspinal choristoma. Intervention: The lesion was surgically removed, and follow-up plain and enhanced MRI images of the patient’s lumbar spine were obtained. Outcomes: After surgery, the patient no longer experienced the burning pain in her lumbar region or the left lower extremity hypoesthesia when the patient was discharged. And there was no evidence of recurrence 2 years after the surgery. Lessons: The MRI presentation of intraspinal choristoma is similar to intraspinal lipoma. Therefore, a pathological assessment is critical to provide an accurate diagnosis.

“…They may be associated with malformations of the ossicles of the ear and abnormal facial nerve aberrations. A pathological diagnosis is necessary [ 32 , 33 ]. Teratomas appear as homogeneous soft tissue in CT images, but may show internal calcification and ossification or a mixture of solid and cystic lesions [ 16 ].…”

Imaging of Temporal Bone Mass Lesions: A Pictorial Review

et al. 2023

View full text Add to dashboard Cite

Tumoral lesions of the temporal bone include benign or malignant tumors and congenital or inflammatory lesions. Temporal bone lesions are difficult to approach. Therefore, making a preoperative diagnosis and considering whether the lesions require treatment are necessary; if they require treatment, then the type of treatment requires consideration. These tumors cannot be observed directly and must be diagnosed based on symptoms and imaging findings. However, the differentiation of temporal bone lesions is difficult because they are rare and large in variety. In this pictorial review, we divided temporal bone lesions by location such as along the facial nerve, along the internal jugular vein, around the endolymphatic sac, in the internal auditory canal/cerebellopontine angle, petrous apex, middle ear, and mastoid, focusing on the imaging findings of temporal bone lesions. Then, we created a diagnostic flowchart that suggested that the systematic separation of imaging findings is useful for differentiation. Although it is necessary to make comprehensive judgments based on the clinical symptoms, patient background, and imaging findings to diagnose temporal bone mass lesions, capturing imaging features can be a useful differentiation method.
