Accessory soleus muscle is an uncommon anatomical variant that may present as a soft-tissue mass in the posteromedial region of the ankle. It is congenital in origin but usually presents in the second or third decade of life. Although it is a rare entity, accessory soleus muscle should be included in the differential diagnosis of soft-tissue swelling of the ankle. Awareness of the clinical presentation and specific findings of computed tomography, magnetic resonance imaging, and electromyography help with diagnosis without surgical exploration. We describe a 30-year-old patient with accessory soleus muscle. Magnetic resonance imaging features of the case are described, and the literature is briefly reviewed.

Pictorial Review

Most imaging findings relating to toxic and acquired metabolic disorders follow a certain pattern with affinity to a specific topographic area, which can help narrow the differential diagnosis. This is especially useful when the clinical presentation can be variable and there is diagnostic uncertainty. Usually, there is bilateral symmetrical abnormality within the deep grey matter structures and the cerebral cortex because of the high metabolic activity and raised oxygen requirements in these areas. Magnetic resonance imaging, particularly diffusion weighted imaging and fluid-attenuated inversion recovery sequences, is very important in differentiating between various aetiologies in this group. Magnetic resonance imaging can be useful in demonstrating both acute and chronic damage, in evaluating treatment response and in disease prognostication. This pictorial review discusses the computed tomography and magnetic resonance imaging appearances of a spectrum of toxic and metabolic disorders observed in a district general hospital with reference to clinical presentation and imaging features that may allow diagnosis. This includes carbon monoxide poisoning, hypoglycaemia, non-ketotic hyperglycaemia, osmotic demyelination syndrome, posterior reversible encephalopathy syndrome, hypoxic ischaemic encephalopathy, the syndrome of delayed post-hypoxic leukoencephalopathy, hepatic encephalopathy and cocaine toxicity.

Primary muscle hydatidosis is very rare. Rupture and spreading of the cyst contents by improper handling may later cause secondary cyst or allergic reactions. Pre-operative recognition of a hydatid cyst is therefore critical. It often presents as a soft-tissue mass, however, and pre-operative recognition of this rare entity is clearly difficult. Here, a case of primary hydatidosis affecting the gracilis muscle is presented, and the magnetic resonance imaging, clinical and pathological findings are described.

Femoris Muscle

Quadriceps muscle strains are common sporting injuries, but occasionally a tear of the rectus femoris muscle can appear as a soft tissue mass of the anterior thigh with or without a significant history of trauma. Between 1992 and 1996, seven patients were referred to the Orthopaedic Oncology Unit at Walter Reed Army Medical Center with an unexplained soft tissue mass of the thigh. Three were active duty soldiers, three were military dependents, and one was a retired serviceman. All patients were men, and the mean age was 32 years (range, 15 to 73). A palpable, mildly tender mass was confirmed on clinical examination. Laboratory studies and plain radiographs were normal. Magnetic resonance imaging showed an obvious, but often ill-defined, lesion at the musculotendinous junction of the rectus femoris muscle. Four patients subsequently underwent a tissue biopsy to rule out a soft tissue sarcoma. Histologic studies showed fibrosis, degeneration of muscle fibers, and chronic inflammatory cells with no evidence of malignancy. A chronic rectus femoris muscle tear can mimic a soft tissue tumor or sarcoma and needs to be excluded in the differential diagnosis. These tears may occur acutely or may represent an overuse injury caused by repeated micro-trauma. Careful history taking, physical examination, and selective radiographic studies, specifically magnetic resonance imaging, can confirm the diagnosis of muscle tear and full functional recovery can be anticipated.

External Snapping Hip

Background: With the increasing sport population, the number of patients with external snapping hip (ESH) has also increased. To detect and visualise pathological soft tissue changes, magnetic resonance imaging (MRI) has been 1 of the most useful modalities. However, only limited studies have investigated MRI and its clinical value in the treatment of ESH in the past. Materials and methods: Between May 2017 and November 2018, 104 patients were diagnosed with ESH at our institution. We excluded patients who did not undergo an MRI ( n = 11), had complaint of bilateral symptom ( n = 17), were not diagnosed hip problems previously (n = 2), and were lost–follow-up within 6 months ( n = 19). After applying the exclusion criteria, 55 patients remained. We classified the patients into 2 groups according–MRI findings: tensed iliotibial band (ITB) and hypertrophied gluteus maximus (GM). We investigated the clinical findings, such as mean age, symptom duration, pain score, grading based on symptom severity, and other radiological findings such as soft tissue signal change and ITB thickness. The variables were compared between the groups. Results: Between the 2 groups defined by MRI findings, the group characterised by tense ITB showed a relatively short symptom duration than the hypertrophied GM group ( p < 0.001). No significant differences in the other variables were found between the groups. Conclusions: ESH has 2 types of MRI features. Compared with the hypertrophied GM group, the tense ITB group showed a shorter symptom duration and a more reversible status.

Abstract Background Kaposiform haemangioendothelioma (KHE) is a rare, locally aggressive disorder. The presenting and imaging features of KHE can overlap with other vascular anomalies and tumours. We aimed to analyse the imaging findings of KHE disorder and highlight features most suggestive of this diagnosis. Methods The clinical features and imaging findings were retrospectively reviewed in 64 patients with pathological diagnosis of KHE. Results Of the 64 patients diagnosed with KHE, 36 patients were < 6 months and 28 patients were ≥ 6 months. The most common presenting features were Kasabach-Merritt phenomenon (KMP, 42.2 %), visible cutaneous lesions (90.6 %), oedema or swelling (43.8 %) and destructive changes or remodelling of adjacent bone (42.2 %). Compared with patients in the group ≥ 6 months, patients in the group < 6 months have higher odds of KMP (P = 0.000), infiltrative lesion with ill-defined borders (P = 0.044). The group ≥ 6 months have higher odds of destructive changes or remodelling of adjacent bone (P = 0.002). In all patients, the lesions in all of the 64 patients were hypointense or isointense compared with muscle on T1-weighted sequences, and hyperintense on T2-weighted or inversion-recovery sequences, nine patients (14.1 %) showed vascularity. There were 28 patients (43.8 %) with characteristic enhancing and infiltrative soft-tissue thickening. Conclusions Presence of visible cutaneous lesions with ill-defined borders, destructive changes or remodelling of adjacent bone, severe thrombocytopenia and consumptive coagulopathy should favour the diagnosis of KHE.

Pol III-related leukodystrophy is a recently recognized category of leukodystrophy with characteristic clinical presentation and imaging findings. These cases are diagnosed by the combination of typical clinical presentation, brain magnetic resonance imaging findings, and the presence of biallelic pathogenic mutations in three specific genes. We present the case of a 6-year-old girl who demonstrated the classic clinical and imaging features of this disorder. This case report aims to raise awareness of this disorder so that it is easily recognized in the appropriate setting.
