Objectives: To evaluate the imaging characteristics of the tumor, emphasizing its location, and to determine the frequency of typical and atypical locations of olfactory neuroblastoma (ONB).

Materials and methods: We retrospectively reviewed the computed tomography and magnetic resonance imaging findings of patients with pathologically proven ONB between April 2000 and April 2023. Demographic information, chief complaints, tumor location, and tumor extension were extracted.

Results: Of the 58 patients, 50 (86.2%) had the epicenter of the mass at the superior part of the nasal cavity, while eight patients (13.8%) had the epicenter at other atypical locations: seven patients (12.1%) at the middle part of the nasal cavity and one patient (1.7%) within both sphenoid sinuses.

Conclusion: ONB is not always present in the upper part or the roof of the nasal cavity, and a significant number of ONBs are occasionally found in the rest of the nasal cavity and other atypical locations.

Teaching point: While demanding urgent management, limited intimal tear (LIT), a rare subtype of acute aortic syndrome (AAS), poses challenges in terms of accurate and timely diagnosis.

Teaching point: Chondrosarcoma of the lower rib may present with only minimal calcified chondroid matrix and may be misinterpreted as a liver lesion.

Teaching point: Popliteal sulcus erosion with soft tissue mass: when in doubt, think of gout.

Macrodactyly, a often congenital anomaly, entails abnormal enlargement of digits, predominantly affecting hands or feet, either in isolation or as part of a syndromic condition. The authors present a case of Macrodystrophia Lipomatosa (ML), a form of macrodactyly, in a 62-year-old patient, emphasizing macrodactyly manifestations through clinical and radiological assessments. Additionally, the authors explore anatomical aspects related to nerve distribution in affected digits, providing a comprehensive understanding of ML. Teaching Point: Explore macrodactyly, emphasizing digits nerve plexus anatomy, which can reveal crucial clues for diagnosing a specific form of this anomaly.

Teaching point: Atraumatic splenic rupture is a rare but life-threatening complication of infectious mononucleosis.

A 57-year-old woman presented with right hip pain. The initial diagnosis was an inflammatory tendinopathy of the gluteus medius without signs of rupture, and the patient underwent an ultrasound-guided corticosteroid injection. However, 1 month later, she presented with a painful swelling on the anterior-external aspect of the right hip/thigh, with a clinical suspicion of malignancy. Magnetic resonance imaging (MRI) scan and ultrasound confirmed the diagnosis of hypertrophy of the tensor fascia lata (TFL) muscle . It is included in the differential diagnosis of soft tissue masses of the anterolateral proximal part of the thigh. The etiology is likely to be associated with gluteal muscle dysfunction. Teaching point: Unilateral hypertrophy of the fascia lata consists of an association with hypertrophy of the tensor fascia lata muscle and pathology of the minimus and medius gluteus muscles.

Teaching point: Wirsung duct duplication is a very rare condition that can lead to chronic pancreatitis.

Teaching Point: Retinal detachment is a rare initial clinical manifestation of lung cancer with intraorbital metastases, early diagnosis on magnetic resonance imaging is important for therapeutic implications.

Teaching point: Benign hyperostosis of the rib is a benign entity consisting of a stress phenomenon that should not be confused with Paget, fibrous dysplasia, or osteoblastic metastasis.
