“…Some lesions in the middle ear are detected early because of hearing loss and other symptoms. In such cases, the lesion is small and difficult to detect using MRI [ 32 ]. Paragangliomas (glomus tympanicum) are found in the cochlear promontory and are usually small at presentation because they cause otologic concerns such as conductive hearing loss, pulsatile tinnitus, or a retrotympanic mass.…”

Imaging of Temporal Bone Mass Lesions: A Pictorial Review

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.

“…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 ].…”

“…Choristoma is considered an abnormal but non‐neoplastic growth of histologically normal tissue in an ectopic body location 1,2 . Choristoma can originate from many different tissues, including bone, cartilage, salivary glands, or muscle, and they are named after the tissue of origin 3–8 . Osseous choristomas are typically composed of thin bones with harvester‐like structures 2 .…”

Key Clinical MessageOsseous choristoma is a rare entity, mainly found on the posterior tongue. It is described as a nodular or exophytic lesion with firm to hard consistency. Clinicians should consider osseous choristoma when confronting lesions with the same features.AbstractOsseous choristoma is an unusual growth of ectopic bone in the soft tissue. This lesion is extremely rare, with a few cases reported in the literature, and they typically appear in the head and neck region, particularly the posterior tongue. The current report presents a case of osseous choristoma in the palate of a 51‐year‐old female. The patient had slight discomfort, which was resolved after surgical excision of the lesion, and no recurrence was observed. This research presents an instance of osseous choristoma in a less common location and concurrently acts as a review of this rare condition.

“…Ectopic salivary gland (SG) tissue may occur in different sites of the body: extra-cranially (larynx, gastrointestinal tract, middle ear, chest wall) [1][2][3][4][5][6] and intra-cranially, with sellar and extra-sellar localizations (e.g. : optic nerve sheath, cerebellopontine angle) [7][8][9].…”

Purpose Salivary gland (SG) tissue and derived neoplasms may occur in the sellar region. As the current literature is mostly limited to case reports, the puzzling case of an inflammatory SG removed by transsphenoidal surgery (TS) and mimicking a prolactinoma prompted us to perform the first systematic review of these unusual conditions. Methods A systematic literature search was conducted according to the PRISMA guidelines. Forty-four individual cases—non-neoplastic enlarged salivary glands (NNESG, n = 15), primary benign (n = 7) and malignant (n = 8) ectopic salivary tumours (ST) and sellar metastasis from eutopic primary ST (n = 14)—were suitable for the analysis of clinical, radiological and pathological characteristics. Therapeutic outcome was reviewed as a secondary endpoint. Results All cases were diagnosed after surgery. NNESG commonly affected young and/or female patients, typically leading to headaches and hyperprolactinemia and originating close to the neurohypophysis. Submucosal SG should be excluded before concluding to an intrasellar NNESG after TS. No gender or age predominance was found for primary ectopic ST, which present as large tumors, with histological phenotypes similar to common ST. Hypopituitarism and diabetes insipidus were more frequent in ST than in NNESG. NNESG and benign ectopic ST rarely recur. Malignant ectopic ST should be distinguished from secondary localizations of eutopic ST reaching the sella by contiguity or metastatic spread; both share a frequent unfavorable outcome. Conclusion Sellar neoplasms derived from SG are rare but misleading conditions and pituitary dysfunction is likely to be more common than currently reported. Appropriate pathological evaluation and multidisciplinary approach are required.
