Case 312: Dercum Disease.

HISTORY: A 29-year-old woman was referred for US of bilateral breasts during evaluation for noncyclical mastalgia predominantly in the left breast of 8 months duration. She had been taking selective serotonin receptor inhibitors for the past 6 months for a clinical diagnosis of generalized anxiety disorder. A detailed medical history revealed breast cancer in the patient's mother and grandmother. There was no history of weight loss or appetite loss, nor was there a history of any altered bowel or bladder habits. The patient was overweight, with a body mass index of 26.8 kg/m2, and appeared anxious during the general physical examination, with an increased pulse (102 beats per minute) and normal blood pressure (118/82 mm Hg). Local examination revealed multiple small mobile painful lesions that were palpable in all quadrants of the bilateral breasts, anterior abdominal wall, and forearm. On further questioning, the patient reported similar painful lesions were present in her mother and one brother. Laboratory investigations showed a normal hemoglobin level (12.4 g/dL; normal range, 12-15 g/dL), a total leukocyte count of 9000 cells per microliter (9 cells × 109/L) (normal range, 4500-11 000 cells per microliter [4.5-11 cells × 109/L]), a normal differential leukocyte count (74% neutrophils [normal range, 40%-80%], 24% lymphocytes [normal range, 20%-40%], and 2% eosinophils [normal range, 1%-4%]), and an erythrocyte sedimentation rate of 5 mm per hour (normal range, 0-29 mm per hour). High-frequency US of bilateral breasts was performed in conjunction with Color Doppler US and shear-wave elastography of representative lesions in the breasts. Similar lesions were also found in the subcutaneous plane of the right forearm and the anterior abdominal wall.

High-frequency US of bilateral breasts (Figs 1, 2) was performed in conjunction with Color Doppler US (Fig 3) and shear-wave elastography of representative lesions in the breasts (Fig 4). Similar lesions were also found in the subcutaneous plane of the right forearm (Fig 5) and the anterior abdominal wall (Fig 6).

Osteoblastoma of the Distal Radius.

Osteoblastomas are rare, benign, bone-forming neoplasms that represent less than 1% of all bone tumors and occur mostly in people aged 10 to 30 years. In long bones, the metadiaphyseal region tends to be most commonly affected. However, to the best of our knowledge, only 11 cases have been reported to occur in the distal radius. We present the clinical, radiological, and histopathological findings of an osteoblastoma of the right distal radius in a 42-year-old woman for whom an open excisional biopsy with nidus removal comprised the treatment and produced a good outcome.

Giant Cell Tumor of the Ring Finger Distal Phalanx.

Giant cell tumor (GCT) is a benign but locally aggressive neoplasm generally located in the epiphysis and metaphysis of the long bones. Its occurrence in the bones of the hand is rare. Giant cell tumors occurring in the hand account for only 2% of all the GCTs reported. The epimetaphyseal region of short long bones is a common site of GCTs in the hand; however, a phalangeal GCT originating in the distal phalanx is extremely rare. We present the clinical, radiological and histopathological findings of a case of GCT of the distal phalanx of the left ring finger presenting with a fungating mass and treated with en bloc resection by disarticulation of the distal interphalangeal joint.

Painful clicking jaw: a pictorial review of internal derangement of the temporomandibular joint.

Temporomandibular joint disorders are a common cause of chronic musculoskeletal pain worldwide. Among these, internal disc derangement is the most frequent type of disorder. Internal derangement is defined as an abnormal positional and functional relationship between the disc and articulating surfaces. Common clinical symptoms include pain and clicking. Imaging plays a key role in diagnosing temporomandibular joint disorders. It is important for the radiologist to detect early imaging signs of internal derangement, thereby avoiding the evolution of this condition to degenerative joint disease. The aim of this article is to familiarise the reader with the spectrum of imaging findings that are encountered at different stages of the disease.

Portal Vein Reconstruction-trans Jugular Intrahepatic Portosystemic Shunt and Portal Vein Stenting in Patients With Extrahepatic Portal Vein Obstruction.

Extrahepatic portal vein thrombosis (EHPVO) is an uncommon cause of portal hypertension. In the long term, patients may develop portal cavernoma cholangiopathy (PCC). Up to 30%-40% of patients with EHPVO may not have shuntable veins and are often difficult to manage surgically. Interventional treatment including portal vein recanalisation-trans jugular intrahepatic portosystemic shunt (PVRecan-TIPS) has been used for patients with EHPVO. However, PV reconstruction-trans jugular intrahepatic portosystemic shunt (PVRecon-TIPS) and portal vein stenting are novel techniques for managing such patients with EHPVO with non-shuntable venous anatomy. In contrast to PVRecan-TIPS, PV reconstruction-TIPS (PVRecon-TIPS) is performed through intrahepatic collaterals. Here we present six cases of PCC who presented with recurrent acute variceal bleeding (AVB) and or refractory biliary stricture. They did not have any shuntable veins. PVRecon-TIPS was performed for five patients whilst PV stenting was done in one. Amongst the six patients, one died of sepsis whilst one who developed hyponatremia and hepatic encephalopathy was salvaged with conservative management. Following the procedure, they were started on anti-coagulation. Decompression of cavernoma was documented in all other patients. Biliary changes improved completely in 40% of patients.

Pulmonary mucormycosis in systemic lupus erythematosus: successful management of a case along with review of literature.

Pulmonary mucormycosis is rare in systemic lupus erythematosus. A 20-year-old lady with lupus nephritis and neuropsychiatric lupus was treated with injection methylprednisolone and cyclophosphamide. After few days, she developed fever, breathlessness, and hoarseness of voice. After neck and chest imaging, possibility of mucormycosis was considered which was later confirmed on microbiological test. Patient was treated with conventional amphotericin B. Literature review was done, and 8 patients with disseminated or pulmonary mucormycosis were identified with SLE. In patients with high index of suspicion, early imaging can help in diagnosis and early and aggressive management even with conventional amphotericin B can result in favorable outcome. Key Points • Pulmonary mucormycosis in systemic lupus erythematosus is rare. • Radiological investigation can guide towards diagnosis. • Early and aggressive treatment can lead to good outcome.

Unusual Pattern of Traumatic Anterolisthesis at Multiple Levels (L3,4,5 Over S1) Because of Pedicle Avulsion: A Case Report.

CASE: Multilevel lumbar spondylolistheses have been reported, but only secondary to degenerative processes. We describe a case where grade 4 anterolisthesis occurred (L3,4,5 over S1) because of multiple level traumatic pedicle avulsion rather than facetal/pars interarticularis/posterior ligamentous complex disruption in a 42-year-old man who presented with paraparesis after a fall from height. Decompression was performed at the L5 level, and pedicle screw fixation was performed at L3, L5, and S1 levels. CONCLUSION: Although such an injury pattern seems catastrophic, it is deemed relatively stable because of the intact posterior ligamentous complex. Restoration of anatomy with stabilization allowed early mobility and satisfactory neurological recovery.

Neglected Two-Week-Old Unstable Fracture-Dislocation of the Hip in a 60 Years Old, Managed with Hip Preservation Surgery.

INTRODUCTION: Hip joint fracture-dislocations are rare injuries and usually result from high energy trauma. Femoral head fractures account for only 7-16% of all hip fracture-dislocations. There is always a controversy regarding optimal surgical treatment modality and approach for the treatment of Pipkin type IV fractures. In a 60 years old individual, various reports favor primary hip arthroplasty as compared to open reduction and internal fixation (ORIF). The posterior approach is preferred because it provides adequate exposure of the acetabular fracture and an opportunity for simultaneous repair of the femoral head and acetabular fractures. Another benefit is that anterior vascular supply to the femoral head and abductor function can be preserved. CASE REPORT: In this case report, we present a neglected 15 days old rare injury (Pipkin type IV femoral head fracture) in a 60 years old male patient that was given a trial of hip preservation surgery by ORIF through posterior (Kocher-Langenbeck) approach. CONCLUSION: A neglected case of Pipkin type IV injury with chances of avascular necrosis and arthritis can be given a trial of hip preservation surgery because in an Indian scenario sitting cross legged and squatting are indispensable activities of daily lifestyle and appropriate surgical technique, adequate exposure, anatomic reduction, and stable internal fixation of the fractures are critical to achieve satisfactory clinical results.

Phakomatoses: A pictorial review.

Phakomatoses or Neurocutaneous syndromes are a heterogeneous group of disorders and have variable inheritance pattern. Currently, more than 30 entities are included in this group. These disorders primarily affect the central nervous system; however, skin, viscera, and other connective tissues can also be involved with variable clinical presentation. We will describe and illustrate the various radiological findings of the common entities through the iconography of the cases presented to our department.
