The spectrum of disorders in musculotendinous trauma (MTt) includes acute traumatic and subacute/chronic lesions caused by repetitive microtrauma. The imaging findings differ in the immature versus the mature skeleton in both categories. Sport-related MTt also depends on age, sex, and type of activity. Magnetic resonance imaging (MRI) is the modality of choice for exploring most MTt injuries and is invaluable for assessing severity and for planning management and return to activity. In some circumstances such as minimally displaced avulsion injuries, MRI findings need to be matched with plain radiographs or computed tomography. Ultrasonography is helpful in exploring superficial structures such as tendons, particularly if dynamic studies are required. Rarely, inflammatory or neoplastic disorders may simulate MTt in the hip and pelvis.

Background: Vaginal adenosis is a rare clinicopathological entity which refers to the presence of glandular endometrial tissue in the vaginal wall. Case report: A gravida 46-year-old woman was presented to the gynecology department with symptoms of chronic pelvic pain. Maternal Diethylstilbestrol (DES) usage has been proven effective in the development of vaginal adenosis. It can also be idiopathic. Its sonographic or magnetic resonance imaging (MRI) findings have not been described in English literature previously. Conclusion: Here, we report the clinical, transperineal ultrasonographic (US) and MRI findings of a pathologically proven case of vaginal adenosis.

Fungal infections of the central nervous system (CNS) are usually identified in immunocompromised patients but rare in immunocompetent hosts. The clinical and imaging manifestations are mainly influenced by types of fungal pathogen and immune status of the patients. The CNS fungal infections can develop through hematogenous dissemination from primary site of infection, cerebrospinal fluid seeding, or direct extension from adjacent sources of infection. Fungal infections can result in meningitis, meningoencephalitis, cerebritis, granuloma, or abscess formation, which imaging findings are often non-specific and difficult to distinguish from bacterial or tuberculous infection, non-infectious inflammatory disease, or even intracranial neoplasm. Vascular complications including vasculitis, cerebral infarction, or mycotic aneurysm are commonly present due to angioinvasion of fungal hyphae. In addition, some characteristic imaging features of fungal infections can be identified by computed tomography (CT) or magnetic resonance imaging (MRI), such as intracavitary projections in fungal abscesses and gelatinous pseudocysts in cryptococcosis that could help suggest the diagnosis. Recognizing the imaging findings of common intracranial fungal infections combined with appropriate clinical setting is crucial for allowing early diagnosis and leading to early specific treatment. The present article reviewed common imaging findings of CNS fungal infections and distinct imaging features of specific pathogens.

Intrathoracic endometriosis is classified into pleurodiaphragmatic endometriosis and bronchopulmonary endometriosis. Bronchopulmonary endometriosis is rare. Computed tomography (CT) findings of bronchopulmonary endometriosis are lung nodules, with or without cavities, or surrounding ground-glass opacities. Features vary with menstrual status. Recently, the usefulness of magnetic resonance imaging (MRI) was reported for diagnosis of intrathoracic endometriosis, but most published reports were about pleurodiaphragmatic endometriosis. We present CT and MRI findings of bronchopulmonary endometriosis in the left lung that showed a gradually enlarging nodule with enhancing area.

Sternalis Muscle

The imaging findings of a normal variant seen on mammography are presented in this article. The sternalis muscle is an uncommon normal variant, seen only in 8% of cadaveric studies. It is increasingly demonstrated with mammography as imaging techniques improve. This normal variant needs to be differentiated from significant pathology and can pose a diagnostic dilemma. In this article the anatomy of this muscle and the imaging findings are discussed. In selected cases computed tomography (CT) or magnetic resonance imaging (MRI) will be required to investigate the mammographic findings further and these modalities are described regarding the assessment of the sternalis muscle.

Objective: The authors report a case of femoral nerve schwannoma by MR imaging findings. Case: A patient presenting with right inguinofemoral pain and swelling was submitted to a Gadolinium-enhanced Magnetic Resonance Imaging (MRI): a schwannoma arising from the femoral nerve in the right inguinofemoral area was disclosed. She  underwent microsurgical procedure, with total removal of the lesion. Postoperatively, the inguinofemoral pain and swelling disappeared, with complete relief of symptoms. Conclusion: The authors stress that femoral nerve schwannoma in the inguinofemoral place should be considered according to MRI findings.

Renal lymphangiectasia is a rare benign condition of the kidney without specific clinical presentations. Classic imaging findings are described in literature. Here, we present a case of renal lymphangiectasia with history of bilateral flank pain and abnormal renal function tests. The radiological appearance on ultrasound (US) and computed tomography (CT) showed features of bilateral renal lymphangiectasia but the patient refused invasive procedure for aspiration of the cysts. So, follow-up of the patient was done by magnetic resonance imaging (MRI). Imaging findings of our case on US, CT, and MRI are discussed along with details of the additional finding of dilated retroperitoneal lymphatic channels, cisterna chyli, as well as the thoracic duct.

Background: Cutis Verticis Gyrata (CVG) is a rare skin disease caused by overgrowth of the scalp, presenting as cerebriform folds and wrinkles. CVG can be classified into two forms: primary (essential and non-essential) and secondary. The primary non-essential form is often associated with neurological and ophthalmological abnormalities, while the primary essential form occurs without associated comorbidities. Discussion: We report on a rare case of primary essential CVG with a 4-year history of normal-colored scalp skin mass in the parietal-occipital region without symptom in a 34-year-old male patient, retrospectively summarizing his pathological and Computer Tomography (CT) and magnetic resonance imaging (MRI) findings. The major clinical observations on the CT and MR sectional images include a thickened dermis and excessive growth of the scalp, forming the characteristic scalp folds. With the help of CT and MRI Three-dimensional (3D) reconstruction techniques, the characteristic skin changes could be displayed intuitively, providing more evidence for a diagnosis of CVG. At the 5-year followup, there were no obvious changes in the lesion. Conclusion: Based on our observations, we propose that not all patients with primary essential CVG need surgical intervention, and continuous clinical observation should be an appropriate therapy for those in stable condition.
