Fetus in Fetu (FIF) is a rare condition where a monozygotic diamnionic parasitic twin is incorporated into the body of its fellow twin and grows inside it. FIF is differentiated from teratoma by the presence of vertebral column. An eight year old girl presented with an abdominal swelling which by X-ray, ultrasonography and CT scan revealed a fetiform mass containing long bones and vertebral bodies surrounded by soft tissue situated on right lumber region. On laparotomy, a retroperitoneal mass resembling a fetus of 585 gm was removed. It had a trunk and four limbs with fingers and toes, umbilical stump, intestinal loops and abundant scalp hairs but was devoid of brain and heart. Histology showed various well-differentiated tissues in respective sites. FIF is a mystery in reproduction and it is scarce in literature in such well-developed stage.

Fetus in fetu is a rare condition associated with abnormal embryogenesis in a diamniotic, monochorionic pregnancy, wherein one of the fetus is enclosed within the body of another normally developing fetus. It should be differentiated from a teratoma because of the later’s malignant potential. Here we report a case of 2 months old girl child who presented with complaints of abdominal distension. USG showed a solid cystic retroperitoneal mass resembling an anencephalic fetus. Contrast enhanced Computed tomography (CT) showed similar findings with visualization of bones resembling femur, sacrum and vertebrae. Findings were correlated with MRI and post-op pathology. The preoperative diagnosis of FIF is based on the observation of vertebral column or limbs in a mass on imaging modalities and our case meets the required criteria.

Fetus in fetu is a condition in wich a fetiform calcified mass often presents in the abdomen of its host, a newborn. It is extremely rare condition, estimated once in 500,000 deliveries and has a 2: 1 male predominantly; with most patient presenting with an abdominal  mass in the first year of life. 5,13 The term fetus in fetu is used to point out an unequal division of totipotential cells of blastocyst where the result is the inclusion of a small cellular mass in the more mature embryo. It was encapsulated, pedunculated and represents a malformed monozygotic, monochorionic, diamniotic parasitic twin. In 80% cases, fetus in fetu is located  retroperitonealy but can be found in unusual location such as in oropharynx, neck, skull mediastinum, pelvis, iliac mesentery, adrenal gland, sacrococcygeal region and scrotal sac.

Tumour calcinosis is a rare clinical and histopathological syndrome characterised by deposition of calcium deposits in different periarticular soft tissue regions of the body. It mainly manifest in childhood/ adolescence as a painless, firm to hard tumour like mass around the joints. Most common regions involved: Shoulder, elbow and hip. An 18 year old male patient presented to the opd with a history of pain and swelling over his left hip since 2 months. On examination, there was a diffuse tender swelling over the left greater trochanter, skin over the swelling was normal with no discharge, no dilated/ engorged veins. Range of motion of left hip was normal, no limb length discrepancies. X-ray: Showed a well define calcified mass over the greater trochanter with no osseous involvement. MRI revealed an encapsulated hypointense mass present posterior to the greater trochanter, mostly in the muscular plane. Lab findings revealed mild hyperphosphetemia. An aspirate from the swelling showed casseousmaterial. En mass removal was done and sent for biopsy. Biopsy showed features suggestive of tumoral calcinosis. Tumoral calcinosis is a distinct clinico-radiopathological entity characterised by soft tissue periarticular calcinosis which mimics a true neoplasm, associated with elevated levels of serum phosphate. It is an extremely rare condition which is seen in the adolescence and requires more studies regarding the surgical and medical management of the same.

Vertebral Kinematics

Tetrapods use their neck to move the head three-dimensionally, relative to the body and limbs. Fish lack this anatomical neck, yet during feeding many species elevate (dorsally rotate) the head relative to the body. Cranial elevation is hypothesized to result from the craniovertebral and cranial-most intervertebral joints acting as a neck, by dorsally rotating (extending). However, this has never been tested due to the difficulty of visualizing and measuring vertebral motion in vivo . I used X-ray reconstruction of moving morphology to measure three-dimensional vertebral kinematics in rainbow trout ( Oncorhynchus mykiss ) and Commerson's frogfish ( Antennarius commerson ) during feeding. Despite dramatically different morphologies, in both species dorsoventral rotations extended far beyond the craniovertebral and cranial intervertebral joints. Trout combine small (most less than 3°) dorsal rotations over up to a third of their intervertebral joints to elevate the neurocranium. Frogfish use extremely large (often 20–30°) rotations of the craniovertebral and first intervertebral joint, but smaller rotations occurred across two-thirds of the vertebral column during cranial elevation. Unlike tetrapods, fish rotate large regions of the vertebral column to rotate the head. This suggests both cranial and more caudal vertebrae should be considered to understand how non-tetrapods control motion at the head–body interface.

✓Fetus-in-fetu is a very rare condition in which one fetus is contained within another. About 100 cases have been reported, and in most of these the fetus was located in the retroperitoneum. The authors describe an extremely rare case of an intracranial fetus-in-fetu in an extraaxial location. This is the eighth intracranial fetus-in-fetu to be reported, the first intracranial extraaxial case, and involves the oldest documented patient with this condition. Histopathological analysis of the mass revealed a degenerated amnionic membranelike tissue, well-differentiated extremities (including fingerlike structures), skin, matured lungs, well-formed intestines, cerebellar and cerebral tissue, and a notochord with ganglion cells. DNA analysis using short tandem repeat polymorphisms confirmed that the fetus-in-fetu mass and the host infant had heterozygous alleles and were of identical sex and genotype.

<p>Multiple clustered dermatofibroma (MCDF) is an unusual variant of dermatofibroma (DF) presentation, localized on one segment of the body. Multiple dermatofibroma is a term for when there are more than 15 dermatofibromas,  which in itself is already a rare condition. The dermatofibromas usually appear in younger adults and are predominantly located on lower parts of the  body. No associations, except one case with pulmonary hypertension, were described in patients with MCDF. Herein we present another case of this rare complaint in a 58 year old female with clustered lesions on the thigh. Pericardial cyst was identified in our patient during routine chest X-ray and the patient is asymptomatic. MCDFs do not usually require treatment unless requested by the patient for cosmetic reason. This variant of MCDF, which is neither congenital nor eruptive, is extraordinarily rare, with only 13 cases reported. Further reports may identify possible associations of MCDF.</p>

Preliminary Study

Anthropological profile in forensic context includes the assessment of parameters as ancestry, sex, age and stature of an individual by the analysis of skeletal remains. Stature can be estimated from decomposed and fully or partially skeletonized remains by means of anatomical or mathematical methods applied on the whole skeleton or single bones. Many authors calculated regression formulae for the living stature estimation by these methods, in particular based on a population similar to the remains recovered. Long bones are commonly used for stature estimation, but, when they are missing, methods involving different parts of the skeleton are needed. In this preliminary study we measured heights of the vertebral bodies in a female Caucasian Italian population, evaluated by images of morphometric X-ray absorptiometry based on dual-energy X-ray absorptiometry in living subjects investigated for routine diagnostic purposes. Thoracic and lumbar segments of the spine were measured and statistical analysis was performed, thus obtaining regression formulae for estimated living stature from thoraco-lumbar spine segments (T<sub>6</sub>-T<sub>12</sub>, L<sub>1</sub>-L<sub>4</sub> and T<sub>6</sub>-L<sub>4</sub>). We propose this method for stature evaluation in physical or forensic anthropology when the spine is available and long bones are missing.

Purpose. Children with neurological disorders, such as cerebral palsy (CP), have a high risk of developing scoliosis during growth. The fast progression of scoliosis implies in several cases frequent clinical and X-ray examinations. We present an ionizing radiation-free, noncontacting method to estimate the trajectory of the vertebral column and to potentially facilitate medical diagnosis in cases where an X-ray examination is not indicated. Methods. A body scanner and corresponding analysis software tools have been developed to get 3D surface scans of patient torsos and to analyze their spinal curvatures. The trajectory of the vertebral column has been deduced from the body contours at different transverse sectional planes along the vertical torso axis. In order to verify the present methods, we have analyzed twenty-five torso contours, extracted from computer tomography (CT) images of patients who had a CT scan for other medical reasons, but incidentally also showed a scoliosis. The software tools therefore process data from the body scanner as well as X-ray or CT images. Results. The methods presented show good results in the estimations of the lateral deviation of the spine for mild and moderate scoliosis. The partial mismatch for severe cases is associated with a less accurate estimation of the rotation of the vertebrae around the vertical body axis in these cases. In addition, distinct torso contour shapes, in the transverse sections, have been characterized according to the severity of the scoliosis. Conclusion. The hardware and software tools are a first step towards an ionizing radiation-free analysis of progression of scoliosis. However, further improvements of the analysis methods and tests on a larger number of data sets with diverse types of scoliosis are necessary, before its introduction into clinical application as a supplementary tool to conventional examinations.

Prishtavamsha Sandhi (joints of vertebral column) is the Cheshtavantha Prathara (movable and floating) type of joint. Twenty four joints are present in Prishtavamsha (vertebral column). Intervertebral joints are the joints which connect vertebrae to each other consists of cartilaginous joints in between the vertebral bodies and synovial joint between vertebral arches. Sandhigatha Vata (osteo arthritis) is one among the Vatavyadhi, which can affect all joints in the body. Sandhigatha Vata (osteoarthritis) will be dominated with symptoms like pain, swelling and impairment of function. In Sandhigatha Vata (osteoarthritis), destruction occurs in the joints due to aggrevated Vata. But it is not clear about the type of destruction observed in the joints. To rule out the various structural changes observed in the joints of Prishtavamsha (vertebral column) this work is being undertaken. Among 100 patients suffering from Prishtavamsha Sandhigatha Vata (osteoarthritis of vertebral column), all patients showed structural changes, 38% having Intervertebral disc prolapse, 22% having spondylosis, 20% having osteophytes, 8% with Osteosclerosis, 6% having spondylolisthesis, 5% with fractures and 1 with stenosis justifies structural changes (Hanthi Sandhi) occurs in Sandhigatha Vata (osteoarthritis). All patients had pain and restricted movements, 80% patient had swelling which justifies the symptoms of Sandhigatha Vata (osteoarthritis).
