Spindle cell lipoma (SCL) is a rare neoplasm occurring predominantly in male patients between the ages of 45 and 70 years. We present a case of SCL arising in the sternomastoid muscle of a 46 year old male patient, which was completely excised at surgery. (Only 4 cases of SCL have been described within skeletal muscle and SCL has not previously been reported within sternomastoid.) The histological and magnetic resonance (MR) imaging features of this lesion are described and the differential diagnosis is discussed, with particular reference to its potential confusion with liposarcoma.

Object Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system, and its prevalence is continuing to increase in the United States. The diagnosis of intraventricular NCC (IVNCC) may be difficult, and surgery frequently fails to resolve symptoms. A retrospective review of magnetic resonance (MR) imaging characteristics and surgery-related outcomes may improve management strategies of this disease. Methods The authors report the presentations, neuroimaging characteristics, surgical management, and outcomes of 30 patients with IVNCC treated over a 10-year period (mean follow-up period 4 years). Cysts were located in the lateral ventricles (five cases), the third ventricle (five cases), and the fourth ventricle (21 cases). One patient had lesions in both the lateral and fourth ventricles. Presenting symptoms were related to hydrocephalus or mass effect from the lesions. All patients underwent computerized tomography (CT) and MR imaging of the brain. Treatment consisted of shunt implantation or primary excision of an IVNCC lesion. Outcomes after operations and reoperations were evaluated in light of enhancement characteristics on MR imaging. Computerized tomography scanning demonstrated IVNCC lesions in 10% of cases, and MR revealed lesions in 100% of cases. In patients in whom gadolinium (Gd) enhancement of IVNCC lesions was demonstrated on MR imaging, the surgery-related failure rate was higher and patients required reoperation, and in those in whom gadolinium enhancement was absent the surgery-related failure rate was lower (64 and 19%, respectively; p < 0.0002). Conclusions Magnetic resonance imaging is superior to CT scanning for detecting IVNCC lesions. The absence of pericystic Gd enhancement on MR imaging is an indication for excision of the lesions. If pericystic enhancement is present, shunt surgery should be performed, and craniotomy reserved for treatment of those patients with symptomatic lesions secondary to mass effect. A treatment algorithm based on patient symptoms, cyst location, and MR imaging Gd enhancement characteristics is proposed.

We report hereby the case of a 61-year-old man who presented with a soft-tissue swelling on the palmar aspect of the thumb. A detailed clinical examination followed by ultrasonography and excisional biopsy confirmed a spindle cell lipoma. Lipomas are rare in the hand and exceptional in the fingers, and we report, to our knowledge, the first spindle cell lipoma in the thumb to help in the differential diagnosis of a similar swelling.

Lipomas are among the most commonly encountered soft tissue tumors in clinical practice, though they are rare in the foot. Although a presumptive diagnosis is typically made clinically, those tumors with atypical clinical features may require radiological consultation. Difficulty arises when radiographic features are not typical of lipoma. We present a fatty soft tissue tumor of the foot with nonadipose elements on magnetic resonance imaging evaluation. Differentiation of lipoma variants (e.g., spindle cell lipoma, atypical lipoma, pleomorphic lipoma, lipoblastoma, angiolipoma) from liposarcoma based on imaging features is not possible, necessitating surgical resection for definitive histological diagnosis.

Inflammatory myopathies comprise heterogeneous disorders. Their etiopathogenesis is poorly understood, because of the paucity of informative experimental models and of approaches for the noninvasive study of inflamed tissues. Magnetic resonance imaging (MRI) provides information about the state of the skeletal muscle that reflects various facets of inflammation and remodeling. This technique has been scarcely used in experimental models of inflammatory myopathies. We characterized the performance of MRI in a well-established mouse model of myositis and the antisynthetase syndrome, based on the immunization of wild-type mice with the amino-terminal fragment of histidyl-tRNA synthetase (HisRS). Over an eight-week period following myositis induction, MRI enabled precise identification of pathological events taking place in muscle tissue. Areas of edema and of active inflammation identified by histopathology paralleled muscle modifications detected noninvasively by MRI. Muscles changes were chronologically associated with the establishment of autoimmunity, as reflected by the development of anti-HisRS antibodies in the blood of immunized mice. MR imaging easily appreciated muscle damage and remodeling even if actual disruption of myofiber integrity (as assessed by serum concentrations of creatinine phosphokinase) was limited. Thus, MR imaging represents an informative and noninvasive analytical tool for studyingin vivoimmune-mediated muscle involvement.

Spindle cell lipoma (SCL) in the scrotum is a very rare presentation with only a few cases reported in the literature. The most common sites for this benign lesion are the neck, shoulder, and back. We present a 72-year-old male patient with painless swelling on the left half of the scrotum with a histopathological diagnosis of SCL.

: The pulmonary type of primary small cell carcinoma of the ovary (SCCOPT) is a rare aggressive malignancy with a poor prognosis, usually occurring in postmenopausal women. Few literatures have emphasized on the magnetic resonance (MR) imaging features. In this paper, we analyze its MR imaging findings in combination with pathological manifestations. We report a case of a 51-year-old woman who presented with abdominal pain and distension. Several tumor markers were elevated. MR scan of the pelvis was performed. It revealed a heterogeneous lobulated mass with solid and cystic components originating from the right adnexa. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy. Histology showed a tumor comprising areas of classical small-cell carcinoma, and SCCOPT was diagnosed based on histopathology and immunohistochemistry. SCCOPT is a rare aggressive malignancy with certain characteristic imaging features. The solid component exhibits slightly higher signal on T2-weighted imaging with fat suppression, restricted diffusion on diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps, and honeycomb-like persistent enhancement. More data are needed to better understand its specific imaging manifestations.
